Leading Sustainable Open Source for HPC: Kitware at the HPSF Conference 2026
March 16 – 20, 2026 | Chicago, IL
As high-performance computing, AI, and accelerated computing expand into new industries and research domains, the demand for scalable and sustainable software infrastructure continues to grow. Kitware is pleased to participate in the second annual High Performance Software Foundation (HPSF) Conference, bringing together leaders from across the HPC community to strengthen open source collaboration and advance modern software infrastructure for next-generation computing.
As both a long-time contributor to open source infrastructure and a provider of production-grade support and consulting services, Kitware brings deep technical expertise grounded in real-world deployments across research, government, and industry. At HPSF 2026, our team will share practical insights from this experience to address key challenges and emerging opportunities for both the HPC and developer communities.

Kitware’s participation in HPSF 2026 reflects our active technical involvement in the foundation’s working groups and infrastructure initiatives. Our team contributes directly to discussions and implementation efforts around CI orchestration beyond commodity cloud hardware, binary provenance and ABI compatibility, artifact signing workflows, and scalable Spack-based environments. These efforts are focused on improving reproducibility, portability, and long-term maintainability across heterogeneous HPC systems.
Our HPC expertise is rooted in hands-on development of core infrastructure. From early MPI support in VTK to the creation and ongoing evolution of CMake, and contributions across CDash, Spack, ParaView, and trame, we have worked on the practical mechanics of building, testing, packaging, and deploying scientific software at scale. This includes addressing real constraints such as multi-platform toolchains, compiler and MPI variability, dependency graph complexity, performance instrumentation, and CI stability across specialized hardware.
Since 1998, Kitware has sustained large, community-driven open source HPC projects through a services-based model designed for long-term technical stewardship. That experience — maintaining portability guarantees, evolving APIs without fragmenting ecosystems, and supporting production deployments in national labs and industry — informs how we approach HPSF today: as engineers contributing to shared infrastructure that must remain reliable, reproducible, and maintainable over decades.
Powering HPC with Open Source
Organizations rely on CMake, Spack, and related HPC technologies to power complex scientific and AI software systems. But successfully scaling these tools across platforms, teams, and specialized hardware requires more than adoption—it demands architectural clarity, performance expertise, and long-term sustainability planning. As systems grow, so do the risks: fragile build pipelines, inconsistent environments, integration bottlenecks, and mounting technical debt.
Partnering with experts helps organizations avoid these pitfalls from the start. It accelerates modernization efforts, reduces costly rework, strengthens reproducibility, and ensures infrastructure is built on proven best practices. Instead of spending cycles troubleshooting or untangling dependencies, teams can focus on advancing research, delivering products, and driving innovation with confidence.
As core contributors to CMake, Spack, ParaView, and related HPC infrastructure, Kitware provides direct access to the experts who design and sustain these technologies. We help organizations deploy scalable, maintainable, and production-ready open source solutions, enabling them to move faster, reduce risk, and build for long-term success.
Talk with our ExpertsConnect with Kitware at HPSF 2026
At HPSF 2026, Kitware’s sessions will highlight practical strategies for improving build performance, strengthening CI infrastructure, advancing secure binary workflows, and scaling Spack-based environments across platforms. These discussions reflect our ongoing commitment to building sustainable open source foundations for modern HPC and AI systems.
We look forward to engaging with the community, sharing insights, and connecting with organizations navigating complex software infrastructure challenges.
