Open Source in the Federal Government - Jordan Kasper, Independent

Monday June 23, 2025 11:20am - 12:00pm MDT

Bluebird Ballroom 3F

The federal government builds and maintains hundreds of thousands of software systems - and it would be difficult to find a system that doesn't rely on open source software. In fact, the government is likely the single largest consumer of OSS in the world and considering the criticality of the mission, the security of those systems is paramount. There has been limited guidance on how government programs should select, consume, contribute to, and publish open source software, but things are getting better! This session will discuss the current landscape of open source in the federal government and present methods for how we can secure our own systems with tools and processes to vet open source projects, ingest that software securely, and support those projects with substantive contributions.
Attendees from government entities, contractors, and members of the community should attend to learn how the government can tackle the supply chain risks inherent in open source while still capturing the benefits that it has to offer. They'll come away with an understanding of how this might impact their work, and how by working together we can build a better open source ecosystem for everyone.

Gopher Meets Crab: A Rust Journey in Cloud Native - Phil Estes, AWS

Monday June 23, 2025 1:30pm - 2:10pm MDT

Bluebird Ballroom 2G

If you've been around the container and cloud native ecosystem for any length of time, you know most major components are written in Go: from Docker to runc and from Kubernetes to etcd! This means that many of the common constructs, for example the OCI specs, or Kubernetes API resources, are easy to use from other Go programs, but not quite as easy when you step outside of the Go ecosystem.

In this talk we'll dive into the experience of trying to use containers from a Rust-written client and delve into existing work from early adopters of Rust. There are quite a few crates that help us along the way, providing some level of parity for Rust developers in the cloud native ecosystem. There are still complexities and hurdles as well, and we'll share our experience navigating this as a long-time Go programmer and Rust newbie.

Attendees will take away some quick tips as well as gotchas for working in the container and cloud native ecosystem as a Rust developer and, who knows, maybe soon the Gopher and the Crab will be the best of friends.

Heterogeneous Linux and RTOS Software Architecture for Low-Price RISC-V Cores - Jim Huang & 繼寬邱, National Cheng Kung University

Monday June 23, 2025 1:30pm - 2:10pm MDT

Bluebird Ballroom 2A

SoCs are increasingly heterogeneous, featuring multiple processor clusters and special-purpose accelerators. As a result, Asymmetric Multiprocessing (AMP) systems must support different operating environments running concurrently on the same chip. This talk outlines the software architecture needed to develop applications for AMP setups, enabling operating systems to interact across diverse homogeneous and heterogeneous configurations. In this way, AMP applications can leverage the parallelism provided by these varied architectures.

Our prototyping efforts focus on low-cost RISC-V processor cores configured as AMP systems, running both the Linux kernel and RTOSes such as ThreadX. This setup includes an IPC layer that implements RPMSG communication between cores. Additionally, our proxy infrastructure highlights how a proxy on the master core can handle POSIX library calls from RTOS-based remote contexts.

Accelerating Computation With GPU Parallel Processing: Enhancing Performance and Efficiency - Akhilesh Shenoy & Aakarsh Jain, Samsung Semiconductor

Monday June 23, 2025 1:30pm - 2:10pm MDT

Bluebird Ballroom 2E

Graphics Processing Units (GPUs) have become key to modern computing, enabling high-performance parallel processing beyond their original role in gaming. Today, they are critical for solving complex computational challenges effectively. To achieve high levels of parallelism, OpenCL is commonly used to break tasks into kernels, which are executed by multiple threads. Optimizing OpenCL performance on GPUs remains a persistent challenge, as it involves fine-tuning both software (OpenCL code, kernels) and hardware. One of the critical factors influencing GPU performance is the effective use of workgroups. The size of workgroups significantly impacts parallelism and efficiency.
This session focuses on key software optimizations in OpenCL, such as efficient memory management, kernel fusion and optimal workgroup sizing in improving GPU performance. We will demonstrate, how optimized OpenCL code can significantly enhance parallel execution and efficiency. This talk also addresses challenges faced by automotive GPUs, including power and thermal constraints with strategies to overcome these. Best practices for writing efficient OpenCL code tailored for automotive GPUs will also be outlined.

Disconnected Environments in a Connected World - Daniel Moch, Lockheed Martin & Eddie Zaneski, Defense Unicorns

Monday June 23, 2025 1:30pm - 2:10pm MDT

Bluebird Ballroom 3F

Most modern software assumes the internet is always available—but what happens when it’s not? Air-gapped environments are more prevalent than you might think. While they are essential in government, they’re also common in finance, healthcare, and manufacturing. Yet, a surprising amount of today’s tooling—from CI/CD pipelines to package managers—relies on network access and fails when that assumption is broken.

Working in these environments means finding new ways to handle familiar problems. In this talk, we’ll look at the challenges teams face when managing dependencies, applying updates, and automating deliveries without internet access. We’ll share practical solutions, real-world examples, and ways to make modern development practices work in restricted environments.

Make Valkey Multi-threaded With Userspace RCU - Jim Huang, National Cheng Kung University

Monday June 23, 2025 2:25pm - 3:05pm MDT

Bluebird Ballroom 2E

This presentation explores how to create a multi-threaded version of Valkey by employing userspace Read-Copy-Update (RCU) to achieve high performance. With fewer than 2,000 lines of code modifications, we introduce a coordinator-worker pattern, enabling key-value stores like Valkey and Redis to handle tasks concurrently across multiple threads while using a per-thread event loop for I/O operations. Userspace RCU facilitates lock-free data sharing between a writer thread and multiple reader threads, dramatically improving read performance.

Our experiments show that the multi-threaded Valkey can achieve over one million operations per second on a standard server.

Navigating the Sea of CVEs: Securing Your Linux Distributions - Jess Lowe & Holly Gong, Google

Monday June 23, 2025 2:25pm - 3:05pm MDT

Bluebird Ballroom 2D

Are you drowning in a sea of vulnerability advisories, wondering why patching one thing doesn't fix everything? Despite a shared origin, a CVE's impact diverges significantly across Linux distributions. Consequently, a fix at the source does not automatically translate to comprehensive protection downstream. Each distribution requires independent patching, leading to a complex web of security advisories stemming from a single flaw.

In this talk, you'll learn how OSV tools can help you navigate this sea of advisories. We'll explore the root causes of advisory proliferation in Linux and demonstrate how OSV.dev aggregates and cross-references vulnerability data at scale to provide a more complete picture. You'll also see how OSV-Scanner accurately identifies vulnerabilities in your Linux systems, considering distribution-specific nuances and offering actionable guidance. By the end of this session, you'll be equipped with the knowledge and tools to patch smarter and secure your Linux infrastructure more effectively.

Improve Load Balancing With Machine Learning Techniques Based on the Sched_ext Framework - Jim Huang, National Cheng Kung University

Monday June 23, 2025 4:30pm - 5:10pm MDT

Bluebird Ballroom 2D

This talk presents a method to enhance CPU scheduling by leveraging machine learning (ML) to extract the key features necessary for task migration, allowing for dynamic and stable optimization of workloads in scenarios prone to CPU imbalance. The approach is built on the sched_ext framework, which integrates eBPF to support user-defined scheduling policies within the Linux kernel.

While conventional approaches maximize CPU utilization, they often overlook contention for lower-level hardware resources, leading to performance bottlenecks -- particularly in compute-intensive servers. By using an ML-based, resource-aware load balancer, this method effectively addresses such imbalances. With sched_ext, we can collect training data and run inference on the model without modifying the kernel.

Our experiments demonstrate that, for certain workloads, this ML-driven approach can outperform EEVDF, offering notable performance gains for the CPU scheduler.

Lightning Talk: LF Energy SEAPATH : Building an Open Source Ecosystem for the Energy Industry - Christophe Villemer, Savoir-faire Linux

Monday June 23, 2025 5:45pm - 5:55pm MDT

Bluebird Ballroom 3C

The LF Energy SEAPATH project has reached a major milestone with its V1 release in January 2025, establishing itself as the open-source reference for virtualized digital substations. Over the past five years, the project has grown into a structured, collaborative effort that bridges utilities, vendors, hardware manufacturers, and tech companies—unifying a traditionally conservative industry around open innovation. This talk will explore the SEAPATH journey: from its inception as a technical initiative to its current role as a strategic enabler of IT/OT convergence in energy systems. Attendees will gain insights into the challenges of engaging industry stakeholders, the best practices that have sustained growth, and the lessons learned in building an ecosystem where open-source principles drive real-world adoption. SEAPATH’s success is also a testament to the power of community-driven collaboration enabled by LF Energy, which has provided a neutral, trusted framework to bring together key players in the energy sector and accelerate open innovation.
