Building Event-Driven WebAssembly on Kubernetes: Runtime, Observability, and Security - Brandon Kang, Akamai Technologies & Nam Hai, Hylatek JSC

Tuesday August 11, 2026 11:00 - 11:30 KST

Orchid 2

As cloud native systems evolve, WebAssembly(WASM) is emerging as a runtime that complements and sometimes challenges container based approaches. With fast startup, strong isolation, and portability, WASM enables efficient and secure event driven workloads.

In this session, we explore how to build and run the systems using WebAssembly on Kubernetes, focusing on SpinKube, an open source project that brings WASM workloads into Kubernetes.

Through a live demonstration, we will deploy and run WASM workloads using SpinKube, highlighting real workflows. We will also compare cold start and execution performance, showing millisecond startup and lower latency than traditional containers. Plus to demonstrate observability using eBPF based telemetry, we enable visibility into runtime behavior without overhead. Attendees will learn how to trace execution, monitor performance, and troubleshoot distributed WASM systems.

Finally, we will talk how WebAssembly improves security and operational efficiency by reducing the attack surface and enabling consistent execution across environments, providing a practical guide for production adoption.

Upstream Kernel Hardening: Recent Progress and Challenges - Gustavo A. R. Silva, Linux Kernel Self-Protection Project

Tuesday August 11, 2026 11:00 - 11:30 KST

Orchid 1

With the release of Linux 7.0, Rust is no longer considered experimental. New and safer components are expected to be written in Rust in the near future. However, the Linux kernel still contains more than 35 million lines of code written in C. This code will remain critical for years to come and, for the benefit of everyone, must continue to be maintained, improved, and hardened where possible.

In the Linux Kernel Self-Protection Project, we care deeply about this, and we've been advancing kernel hardening upstream for several years. In this presentation, we'll review recent hardening efforts and discuss the challenges we continue to face as we work toward our ultimate goal of eliminating classes of bugs and methods of exploitation in the upstream Linux kernel.

Squeezing Every Millisecond: A Practical Guide To Optimizing Time To First Token With OSS Muscle - Hrittik Roy, Platform Advocate

Tuesday August 11, 2026 11:00 - 11:30 KST

Grand Ballroom 2-3

Large language models are getting faster GPUs every year, yet users still notice the pause before the first word appears. That pause has a name: Time To First Token (TTFT). And in production LLM systems, shaving even a few hundred milliseconds from it can dramatically change how responsive an application feels.

This talk tells the story of where those milliseconds go.

We will walk through the lifecycle of a request in modern LLM serving systems and explore the practical techniques engineers use to reduce TTFT in real deployments. Using examples from open source stacks like vLLM, TensorRT-LLM, and Hugging Face TGI, we will examine four powerful optimization levers: KV cache strategies, speculative decoding, model quantization, and batching policies.

Instead of focusing only on theory, the session highlights the tradeoffs practitioners face. When does speculative decoding actually help? When does batching hurt latency? When does quantization reduce memory pressure enough to speed up the first token?

Attendees will leave with a practical playbook for diagnosing TTFT bottlenecks and choosing the right optimization strategy for their model, infrastructure, and workload.

SBOMs Aren't Enough. Secure Your Software Supply Chain End-To-End - Yongjae Chung, New York University Secure Systems Lab & Justin Cappos, New York University

Tuesday August 11, 2026 11:00 - 11:30 KST

Chrysanthemum

You probably heard that SBOMs are helpful, but did you know that an SBOM only addresses a fraction of what can go wrong in your software supply chain? The SLSA (Supply Chain Levels for Software Artifacts) specification identifies 9 distinct threat areas, spanning from source code, all the way to package distribution. Most development teams address one or two of these and call it a day, leaving gaps that real-world attacks like SolarWinds and Log4J have already exploited. We understand that it is difficult to cover all aspects when it comes to the software supply chain.

How about we make this much easier? In this talk, we will present an overview of the modern software supply chain threat model, and show how you can provide integrity throughout the whole process of your software development life cycle. We will introduce an easy-to-setup, end-to-end open source stack, built from frameworks and tools within the CNCF/OpenSSF ecosystem.

Self-Healing Rollouts: Automating Production Fixes With Agentic AI - Kevin Dubois, IBM & Carlos Sanchez, Adobe

Tuesday August 11, 2026 11:40 - 12:10 KST

Orchid 2

Your software rollouts to production are probably always flawless, right? For the rest of us, once in a while we do run into issues when releasing code to production. Even with robust CI/CD, production rollouts can hit unexpected snags. While in Kubernetes, ArgoCD and Argo Rollouts excels at Progressive Delivery and automated rollbacks to mitigate deployment issues, what if we could go a step further?

This session explores how to elevate your release process by integrating Agentic AI and asynchronous coding agents, with Argo Rollouts canary deployments. We'll demonstrate how an intelligent agent can automatically analyze a rollout failure, pinpointing the root cause. Beyond diagnosis, these agents can take proactive steps on your behalf, suggesting and even implementing code fixes as new pull requests, which can be redeployed automatically after PR review. This approach moves us closer to truly self-healing deployments.

Join us to learn how to combine the power of cloud native projects like Kubernetes, ArgoCD and Argo Rollouts with the autonomous capabilities of Agentic AI, achieving a release experience that is not only seamless but also resilient.

Getting Started With Kernel Programming: The Linux Kernel Mentorship Program - Jori Koolstra, Independent

Tuesday August 11, 2026 11:40 - 12:10 KST

Orchid 1

The Linux Kernel is one of the most influential and widely-used open source software projects today. However, getting started -- understanding the code and contributing to it -- can be quite daunting. Kernel code often carries history and conventions that are not always documented, but are rather shared by the community as tribal knowledge. Moreover, understanding operating-system-level source code comes with its own unique challenges: there is no libc, you need to know about low-level primitives like memory barriers and various types of locking mechanisms, and memory handling errors can bring the whole system down (no garbage collection either, of course!).

The Linux Kernel Mentorship Program (LKMP) addresses some of these difficulties and aims to mentor prospective contributors to overcome the initial hurdle -- because everything becomes easier after your first contribution. The program is led by experienced kernel maintainers with the assistance of regular contributors and is open to anyone.

In this talk I will detail my experience as an LKMP mentee and explain how I have progressed since. I will also explain how you can get started with a small patch!

Stop Trusting a Black Box: The Economic Case for Open, Sovereign AI - Vincent Caldeira, Red Hat

Tuesday August 11, 2026 11:40 - 12:10 KST

Grand Ballroom 2-3

As AI matures from a novelty into a strategic asset, 79% of organisations now prioritise sovereignty to mitigate vendor lock-in and secure critical data. Despite this, the market remains paralysed by a paradox: while open models have achieved performance parity with proprietary systems at a fraction of the cost, they remain massively under-utilised due to perceived friction and trust gaps.

This session dissects this market inefficiency, with insights from LF Research revealing how closed-source dominance is often driven by inertia rather than superior capability. We will explore how to operationalise true independence by rejecting "open-washing" in favour of rigorous frameworks that demand full model completeness: verifying everything from training data to weights. Join us to learn how to transition from renting black-box APIs to architecting a transparent, reproducible, and economically superior AI stack.

One Binary, Every Package Manager: Shipping a Rust CLI To PyPI, Npm, Homebrew, Winget, and Beyond - Ajit Kumar, Independent

Tuesday August 11, 2026 11:40 - 12:10 KST

Chrysanthemum

Most dev tools die in obscurity because installation friction kills adoption before the first command is run. This talk provides a battle-tested playbook for solving that problem using evnx—a Rust CLI for validating and secret-scanning `.env "files"—as a real-world case study.

Launched in early 2026, evnx achieved thousands of cross-ecosystem downloads within weeks by treating distribution as a first-class engineering concern. The session breaks down a complete distribution matrix:

Registry Packaging: Using crates.io as a source of truth, Maturin for native Python wheels, and npm wrappers for platform-specific binaries.
OS Package Managers: Automating Homebrew formulas via cargo-dist, plus Scoop and Winget submissions.
Developer Integration: GitHub Actions with SARIF output, pre-commit hooks, and lightweight Docker CI images.
Supply-Chain Security: Leveraging PyPI Trusted Publishing (OIDC), provenance attestations, and cosign for signed containers.

Attendees will receive reusable GitHub Actions workflows and manifest templates from the public evnx repo to ship any Rust CLI across ecosystems without sacrificing security or maintainer sanity.

Beyond Round-Robin: GPU-Aware Load Balancing for LLM Inference in Kubernetes - Seokhwan Kong, NETLOX

Tuesday August 11, 2026 13:35 - 14:05 KST

Orchid 2

Standard load balancers route LLM requests without awareness of KV-cache state or GPU queue depth — causing inflated Time-To-First-Token and wasted accelerator capacity.

loxilb closes this gap with an eBPF-native AI gateway. The L4 layer uses XDP/TC and kernel sockmap for zero-copy forwarding. The L7 layer adds API-key validation, token-quota enforcement, and accelerator-aware routing via Consistent Hashing with Bounded Loads (CHWBL).

This talk focuses on KV-exact routing for P/D disaggregated deployments. When requests share a prompt prefix, prefill GPUs recompute identical KV tensors repeatedly — wasting up to 80% of GPU cycles. Tier 1.5 eliminates this: loxilb tokenizes the prompt in-process (HuggingFace Rust tokenizer via CGO), computes block hashes matching vLLM's internal format, and routes to the exact GPU already holding those KV blocks — via a live inventory fed by vLLM's native ZMQ event stream.

Unlike serving-layer schedulers (llm-d, Dynamo), this runs in the eBPF data-plane hot path with no Kubernetes dependency — works on bare metal, VMs, and BlueField DPUs.

We'll trace a live request through the P/D testbed and share lessons from building GPU-state-aware routing

KNOD: In-Kernel Network Offload Device for GPU-Accelerated Packet Processing - Taehee Yoo, Rebellions & Hoyeon Lee, SUSE

Tuesday August 11, 2026 13:35 - 14:05 KST

Orchid 1

GPU compute resources remain inaccessible to the Linux kernel without userspace runtimes (ROCm, CUDA), forcing network packet processing to stay CPU-bound regardless of available GPU capacity.
We present KNOD (in-Kernel Network Offload Device), a Linux kernel framework that enables GPU-accelerated network packet processing entirely within the kernel. KNOD compiles and launches GPU kernels natively, dispatching packet processing workloads directly to the GPU — no ROCm, no userspace involvement, using only publicly documented hardware interfaces.
XDP offload is KNOD's first use case. Building on our LPC 2025 talk, this talk covers: in-kernel GPU kernel compilation targeting AMD GFX9/Vega ISA with post-processing optimizations (latency: ~118µs → ~46µs); a lock-free GPU-side queue between NIC RX path and GPU compute; and branch divergence mitigation to maximize SIMT utilization across heterogeneous packet flows.
At equivalent throughput (~32 Mpps), KNOD reduces system-wide CPU utilization from 40% (CPU-based XDP) to 17-20%. We discuss lessons from MACsec/WireGuard offload attempts and the path toward KNOD as a general kernel framework for GPU-accelerated network functions.

Optimizing ML Inference Across Heterogeneous Accelerators - Sanjiban Sengupta, CERN, University of Manchester

Tuesday August 11, 2026 13:35 - 14:05 KST

Grand Ballroom 2-3

Machine learning is central to high-energy physics,.These environments impose strict latency, throughput, and memory constraints, requiring data processing at unprecedented rates. Addressing these demands requires efficient, hardware-aware inference across heterogeneous architectures.

The ML4EP team at CERN is developing an integrated ecosystem for this purpose. We present recent advances in efficient ML deployment. First, aie4ml ports trained models to next-generation AMD FPGAs for ultra-low-latency inference. PQuantML complements this with hardware-aware pruning and quantization, reducing model size and compute cost while preserving performance.

For CPU and GPU inference, SOFIE translates trained models into optimized C++ for heterogeneous systems. Using alpaka, it enables backend-agnostic execution while minimizing data movement. It integrates with PQuantML to support quantized models and is deployable in both online systems and offline workflows.

When global AI development being centralized around proprietary "black-box" models, the demand for Sovereign AI has become a national priority for many countries, including South Korea. True sovereignty requires more than just local data or local LLMs; it demands independence across the entire stack—from silicon up to the software services, as well as AI model itself.

How I Tricked ArgoCD Into Sharding on a Single Cluster - Faeka Ansari, Slice Financial Bank

Tuesday August 11, 2026 14:15 - 14:45 KST

Orchid 2

One controller at 846m CPU. The other at 6m. Both running. Both supposedly doing the same job.

We had two ArgoCD application controllers. Scaling looked solved on paper. Except -- one was doing all the work and the other was just... sitting there.

The thing nobody tells you when you first set up ArgoCD HA is that sharding works at the cluster level, not the application level (sadly). So when you only have one cluster -- it doesn't matter how many controller replicas you spin up. The work doesn't split. It all piles onto one pod.

We were running 300+ apps across 11 EKS clusters in a banking environment. Dropping availability was not an option. So we went digging.

What we found was not in the official docs. It was a trick - something so counterintuitive that the first time I thought of it, I laughed. Then I tried it. Then it worked.

This talk is the story of that fix -- how we found it, why it works, and how we shipped it safely to production using Terraform without touching a single app config.

Grand Ballroom 2-3

"Let’s be real: My AI has dementia."
"Vibe-coding in real: Me and My AI is stupid"
Welcome to the "Vibe Coding" era, where anyone can prompt their way to complex code. But as a 17-year-old developer who "bullied" LLMs to build a custom Linux Based OS (MaruxOS) from scratch, I’ve seen the ugly truth: AI is a brilliant assistant, but a chronic liar with a 5-minute memory.
In this session, I expose the messy reality of AI-native development. I’ll share how I battled "Contextual Dementia"—where AI forgets my ARM64 architecture mid-patch—and survived "Mindless Yes-Clicking Syndrome," where a single trusted prompt almost nuked my entire glibc.
Key Takeaways:
The Hallucination Hunter: Sniffing out AI’s "confident bullshit."
The Dementia Doctor: Managing AI’s memory loss to maintain architectural integrity.
The Final Decider: Moving beyond the "Yes-Clicking" trap to take true technical ownership.
AI might be writing the code, but only a real engineer can stop it from burning the house down.

From Contribution To Culture: 14 Years of Building an OSPO That Outgrew Itself - Darae Ahn, Samsung Electronics

Tuesday August 11, 2026 14:15 - 14:45 KST

Chrysanthemum

Over the past decade, many organizations have established OSPOs to manage open source usage and compliance. However, building a sustainable open source culture requires more than policies and processes.

This session shares a 14-year journey of an OSPO that evolved from a contribution-focused group into a broader organization encompassing usage, compliance, and internal enablement.

It explores how open source practices were embedded into engineering culture through project incubation, developer engagement, and internal leadership programs. Over time, these efforts led to a shift where open source activities became self-sustaining, with teams proactively initiating projects and contributions.

The session also reflects on an unexpected outcome: talent mobility. As internal open source leaders grew, many moved on to new opportunities, revealing both retention challenges and the broader impact of cultivating open talent.

Key lessons include the balance between control and autonomy, the role of leadership in cultural change, and how open source can be viewed not only as a compliance requirement, but as a long-term investment in culture and organizational brand.

The Butterfly Effect of a Broken Disk: Top-Down Ceph Troubleshooting To Upstream Contribution - Sangyun Lee, CJ Olivenetworks

Tuesday August 11, 2026 14:55 - 15:25 KST

Orchid 2

Tech blogs usually talk about huge Ceph clusters with thousands of disks. But in reality, many of us run smaller on-prem setups. I will share my real experience of debugging a small Ceph cluster (10 nodes, 10 NVMe, 15 normal SSDs) and how tracking a slow app led me to write an upstream C++ patch.

It started when our Valkey (Redis) pods suffered from severe write latency. We checked CephFS metadata and Istio network metrics, but they were fine. So we dug into the storage layer using ceph osd perf. We saw huge latency on one specific node. Looking at the kernel logs (dmesg -k), we found a failing NVMe disk. I will explain the "Slow OSD" issue—how one broken disk can freeze a 3-replication cluster.

During this outage, reading ceph osd perf was very frustrating because the OSD IDs were completely unordered. Since it made debugging harder, I decided to fix it. I looked into Ceph's C++ code, changed the unordered hash map to a sorted vector (std::sort), and opened PR #67915 (https://github.com/ceph/ceph/pull/67915). I will share my experience discussing the fix with Ceph maintainers and why I believe engineers should fix the open-source tools they use.

Bridge X86-64 Applications To ARM64 and RISC-V With Dynamic Binary Translation - Jim Huang & Chi-Kuan Chiu, National Cheng Kung University

Tuesday August 11, 2026 14:55 - 15:25 KST

Orchid 1

Running unmodified x86-64 binaries on ARM64 and RISC-V Linux systems remains important, but existing solutions often involve high overhead or depend on platform-specific hardware. Box64 addresses this gap with a wrapping-first architecture that prioritizes native execution by routing calls into host libraries through ABI translation, while reserving JIT compilation for guest code that cannot be directly mapped.

This session presents the core design of Box64 in three parts. First, a native wrapping layer that spans hundreds of libraries, handling entry-point interception and callback bridging. Second, a multi-pass JIT compiler that applies optimizations such as flag liveness analysis and deferred flag computation. Third, system-level integration techniques that enable practical deployment, including container bypass, mixed-bitness coordination with Wine, and memory ordering support on weakly ordered architectures.

We will also share performance results on ARM64 and RISC-V platforms, showing how Box64 achieves near-native performance in favorable cases and significant speedups over traditional emulation approaches.

Open Source AI Agents on User-Owned Infra: K3s, MCP, and GPU Sharing in Practice - Miley Fu, OlaresOS

Tuesday August 11, 2026 14:55 - 15:25 KST

Grand Ballroom 2-3

Most open-source AI demos stop at a chatbot, but real users want agents that can work with private files, call tools, and run close to their important data without sending everything to the public cloud.

This talk shows a practical reference architecture for private agent workflows on a single-node K3s-based personal cloud, including local model serving, private knowledge bases, app sandboxing, secure remote access, and multiple GPU allocation modes for competing AI workloads.

Using an open-source personal cloud OS as a case study, I will share what works, what breaks, and which design choices matter when you try to make local AI usable by developers, creators, and small teams rather than just homelab experts.

How AI Is Changing Open Source Communities: Lessons From OpenEuler - Jianmin Wang, openEuler Community

Tuesday August 11, 2026 14:55 - 15:25 KST

Chrysanthemum

Artificial Intelligence is reshaping how software is developed and maintained. From code generation to automated reviews, AI tools are increasingly influencing how open source communities collaborate. This also introduces new challenges, including how to handle AI-generated contributions, maintain trust and code quality, and define governance for AI-assisted workflows.

In this session, we share experiences from the openEuler community in integrating AI into development processes, including AI-assisted code review, package maintenance, and community guidelines for AI usage, as well as work on frameworks such as Intelligence BooM.

We will discuss how these changes affect contributor workflows, what challenges maintainers face in practice, and what approaches have worked so far. The goal is to provide practical reference points for other open source communities exploring similar directions.

From Region To Multi-AZ: Building Resilient Cloud Infrastructure With OpenStack, Kubernetes, and OVN - 승진 한, kt cloud

Tuesday August 11, 2026 15:55 - 16:25 KST

Orchid 2

As cloud service providers evolve their infrastructure, Multi-AZ architecture becomes essential for service continuity, failure isolation, and operational resilience. However, building a Multi-AZ cloud with open source technologies is not simply about spreading components across data centers. It requires design decisions across compute, networking, storage, observability, automation, and failure validation.

This session shares a CSP’s journey from a region-centric architecture toward a Multi-AZ cloud model using open source technologies such as OpenStack, Kubernetes, OVN, Kube-OVN, OpenStack-Helm, Cluster API, Ceph, and cloud native observability tools.

The talk will cover regional versus AZ-local service design, OpenStack control plane deployment on Kubernetes, zone-aware networking, storage replication, image availability, observability, and DR validation. It will also discuss trade-offs in traffic locality, failover behavior, data consistency, and complexity.

Rather than presenting a vendor-specific platform, this session focuses on reusable architecture patterns and lessons for cloud operators who want to build resilient open cloud infrastructure with open source software.

Maximizing Heterogeneous Memory Bandwidth in Multi-Socket Systems - Rakie Kim, SK Hynix; Yunjeong Mun & Honggyu Kim, SK hynix

Tuesday August 11, 2026 15:55 - 16:25 KST

Orchid 1

The advent of heterogeneous memory like CXL allows systems to secure additional bandwidth, but effectively utilizing it remains challenging. While widely adopted memory tiering optimizes latency by migrating hot pages to fast memory, bandwidth-intensive workloads require utilizing multiple memory tiers simultaneously.

To address this, Weighted Interleaving was introduced to distribute pages proportionally based on each node's bandwidth. However, it has a critical limitation: it ignores the physical topology of multi-socket systems, often leading to inefficient cross-socket memory accesses.

To resolve this, we introduce Socket-aware Weighted Interleave, an advanced memory policy currently being upstreamed to the mainline Linux kernel. It recognizes multi-socket boundaries, preventing performance degradation from unintended remote accesses and maximizing total throughput via localized allocation.

This advanced policy is a newly integrated feature of HMSDK, an open-source toolkit introduced last year. This session will focus primarily on this new capability, exploring how HMSDK efficiently manages large-scale CXL and heterogeneous memory systems.

MCP Adoption and Why OSPO Skills Matter - Ana Jiménez Santamaría, Linux Foundation (TODO Group and PyTorch Foundation)

Tuesday August 11, 2026 15:55 - 16:25 KST

Grand Ballroom 2-3

As organizations explore the Model Context Protocol (MCP), many of the early conversations naturally happen around AI tooling, integrations, and experimentation. At the same time, MCP may also raise questions that are familiar to Open Source Program Offices (OSPOs) and related teams or professionals with open source management experience, including governance, contribution strategy, standards engagement, and cross-functional coordination

This talk reflects on what organizations might gain by bringing those perspectives into MCP discussions earlier, as well as into their broader Agentic AI strategy. Rather than treating MCP only as a technical AI topic, the session will explore it as an area where open source process knowledge may also add value. Attendees will leave with ideas for how OSPOs can contribute to MCP adoption in practical, collaborative, and organization-aware ways

Skills-as-Packages: A Package Manager for AI Agent Skills - Brahada Srinivas, Amazon

Tuesday August 11, 2026 15:55 - 16:25 KST

Chrysanthemum

AI agents like Claude Code, Cursor, and Codex learn libraries via SKILL.md files, but these skills are currently unversioned, ungoverned, and unshared. We solved code dependency management with pip and npm — now it's time to solve it for AI knowledge.
This talk presents an open-source, package-manager-style system for agent skills. Skills are linked to their packages, versioned with semver, declared in skills.toml, and locked via skills-lock.toml — just like regular dependencies.
The CLI (skills add, install, lock, publish) feels native to any developer using pip or uv.
We'll cover:

The SKILL.md open standard (YAML frontmatter + Markdown) — model-agnostic and runtime-agnostic
Manifest format supporting version constraints, inheritance, and monorepo scoping
Resolver that enforces constraint narrowing across org hierarchies
Registry with publishing, discovery, approval workflows, and security scanning
Real cases where this prevented production incidents by keeping agents on correct, up-to-date patterns

Live demo: Add a skill, resolve dependencies, publish it, and watch a new engineer's agent instantly get the right knowledge - no onboarding docs required.

What Happens When Your AI Agent Meets OPA - Jyoti Bisht, Harness

Tuesday August 11, 2026 16:35 - 17:05 KST

Orchid 2

Tom and Jerry has run for over 80 years. Every episode follows the same plot: Tom builds an elaborate trap, Jerry walks straight through it, the house is destroyed, and the owner blames Tom. Sound familiar?

This talk is structured exactly like a Tom and Jerry cartoon except Tom is OPA and Jerry is your AI agent. Jerry is not malicious. He just wants the cheese. He will find every gap in every policy, squeeze through every webhook, and retreat to his mouse hole (MCP) the moment Tom gets close. The audience will root for Jerry. Jerry is still the problem.

We walk through three episodes. Episode one: Jerry discovers he can call kubectl delete and Tom's first policy stops him — but not before he's renamed two deployments. Episode two: Jerry finds a namespace Tom forgot to cover and provisions a GPU node at $8/hour. Episode three: Jerry and Tom finally cooperate — the agent runs a legitimate right-sizing workflow, OPA approves every step, and the cluster is actually better for it.

You'll leave with an OPA policy library for agentic tool-call governance, Argo Workflows, and a threat model built from real agent misbehaviour.

Flexible Paging in Linux: Per-process Page Size - Dev Jain, Arm Ltd

Tuesday August 11, 2026 16:35 - 17:05 KST

Orchid 1

Applications often run faster on a 64K page size kernel than on 4K. This is because larger pages reduce TLB pressure and pagetable walk overhead, greatly improving memory access speed. But, sysadmins are hesitant to use a 16K/64K kernel as most applications have been historically tuned for 4K pages, and larger pages can increase memory waste due to internal fragmentation. This creates a tradeoff between performance and memory waste.

We propose a design that changes the game by separating the page size of the user and the kernel. Instead of enforcing a single system-wide page size, processes can operate under different page-size ABIs. A performance-critical app can use a 64K page-size ABI while still running on a 4K kernel. We achieve this by enabling Linux to provide memory in 64K chunks via 16 contiguous 4K pages, and by translating operations on the 4K page table into a 64K “native” page table that serves as the actual hardware page table.

At the same time, lightweight or memory-sensitive applications can continue using 4K pages to minimize memory waste. All of this happens on the same Linux kernel, without requiring separate builds of the kernel.

Benchmarking Beyond OpenSearch: Multi-Engine Vector Search Performance With OSB - Mike Oviedo, AWS

Tuesday August 11, 2026 16:35 - 17:05 KST

Grand Ballroom 2-3

As vector search becomes foundational to AI workloads, teams need reliable ways to evaluate engine performance before committing to one. We extended OpenSearch Benchmark (OSB) to support Milvus and Vespa alongside OpenSearch, making it possible to compare throughput, latency, and recall across engines using the same datasets and query patterns.

In this talk, we'll walk through how OSB's new engine-as-module architecture lets you benchmark any search engine with a single CLI command. We'll show how customizable workload parameters control everything from HNSW graph construction to bulk ingestion strategies, and demonstrate how to visualize comparative results in OpenSearch Dashboards, turning raw benchmark data into actionable performance insights.

Whether you're evaluating engines for a new project or optimizing an existing deployment, you'll leave with practical knowledge of how to run your own benchmarks and how to extend OSB to support additional engines by implementing five functions.

Computer Programming Is Dead; Long Live AI-First Programming - Stephen Chin, Neo4j & Cassandra Chin, Independent

Tuesday August 11, 2026 16:35 - 17:05 KST

Chrysanthemum

Computer science graduates are facing an increasingly difficult job market. Recent data shows a sharp decline in employment outcomes for computer science majors, highlighting the mismatch between what universities teach and what employers now demand. The traditional model of teaching syntax first and hoping students eventually build something useful is no longer working. In this keynote we argue that programming as we knew it is effectively dead. The future lies in AI-First programming, built on the simple loop of try, learn, and grow. Learners try building code with AI assistance, learn by unpacking the generated code and asking AI for detailed explanations, and grow by testing and extending real applications. This loop not only builds confidence but also ensures we grow the generation of AI engineers that companies are desperate to hire.

From Frankenstein To Kamaji: Lessons in Building a Single CAPI Cluster Across Multiple Providers - Antonia von den Driesch, Giant Swarm

Tuesday August 11, 2026 17:15 - 17:45 KST

Orchid 2

At Giant Swarm we use Cluster API to provision and bootstrap our k8s clusters. With this setup, control plane (CP) and worker nodes must run on the same infrastructure which was never an issue so far...

However, in bare-metal environments, using 128-core servers for CP nodes is luxury. It's far more efficient to host them as virtual machines on a hypervisor while keeping workers on physical hardware. But can we get around CAPI's limitations?

We will walk through how we built Frankenstein's cluster by mixing vSphere for the CP and Proxmox for workers as a testing ground. While technically functional, this required "hacky engineering". We will share the hurdles we hit and the operational risks of this hybrid cluster setup.

Finally, we will demonstrate how we solved this challenge with a cleaner, upstream-friendly alternative. Kamaji lets us run the CP as pods in a management cluster. We achieved even better resource optimisation with full native community support and no custom hacks.

Implementing a Stateless V4L2 Decoder Driver: Architecture and Lessons Learned - SungHo Lee, Chips&Media

Tuesday August 11, 2026 17:15 - 17:45 KST

Stateless video decoding has become the standard approach in V4L2 using the Request API, but implementing a stateless decoder driver remains complex. It requires careful handling of codec parameters, buffer management, and coordination between userspace and the kernel.

This session presents a practical overview of implementing a stateless V4L2 decoder driver based on real development experience. It covers how SPS/PPS and per-frame parameters are passed from userspace, how reference frames are managed, and how hardware constraints are handled within a generic V4L2 framework.

We also discuss common pitfalls such as synchronization issues and buffer lifecycle management, and highlight key differences from traditional stateful decoders.

GitAIOps: A 4-Layer Architecture for Predictable AI-Assisted Operations - Hoon Jo, Megazone

Tuesday August 11, 2026 17:15 - 17:45 KST

Chrysanthemum

AI agents have no memory between sessions. Every conversation starts from zero. Git becomes the only persistent memory an AI agent can rely on. GitAIOps is the pattern built on this principle: Git is the memory, and a 4-layer architecture defines what goes into that memory.

I applied this to a production migration: 15 Helm releases, Kafka ZooKeeper-to-KRaft, Redis-to-Valkey, full observability stack rebuild. The question: what does Git need to contain so any AI session picks up where the last one left off?

The answer is a 4-layer Git structure, each layer born from a production failure.
Layer 1: Human plans in Git (36 files, 23,854 lines). Too verbose for AI.
Layer 2: Distilled AI context in Git (6 files, 1,254 lines). 19:1 compression as a project state dashboard.
Layer 3: Command Guardrails in Git (117 files). Enforced ordering, no AI-generated commands.
Layer 4: Locked values in Git (30 files). Zero interpretation, reviewed like code.

Every AI action reads from Git, executes, and commits back. The loop is closed.

DEV: 2 weeks → 2 days. PROD: 1 week → 1 day. The session covers the architecture, each layer's failure, and real production artifacts.

Personalisation and Specialisation of Search With OpenSearch Agentic Search - Cedric Pelvet & Aswath Srinivasan, AWS

Tuesday August 11, 2026 17:15 - 17:45 KST

Grand Ballroom 2-3

Agentic search lets you ask in Natural Language and have OpenSearch plan and execute retrieval. The Query Planner re-writes Natural Language to OpenSearch DSL using SOTA LLMs. This works amazingly well but not without important limitations:

1/ The biggest factor is added latency for remote inference. eCommerce Search demands sub-100ms response times. Even the best results when slow lead to search abandonment.
2/ We'll demo overcoming latency by hosting SLMs locally within OpenSearch nodes using vLLM/Ollama. This is faster & cheaper, but SLMs suffer quality decline in query re-writes. We'll explore fine-tuning with domain-specific data—proving fine-tuned SLMs beat SOTA LLMs.
3/ Relevance remains generic even with Agentic Search. We'll show how to improve it using user and business contexts with hybrid search and reranking.

This hands-on talk covers:
1/ Search Latency with Remote Inference
2/ Locally hosting SLMs using vLLM/Ollama
