Events & Workforce Expertise

Organization

STEP consists of an accomplished team of HPC tools professionals and representatives from vendors, facilities, and application teams. The team members include a number of representatives of widely used tools at HPC sites, including application profiling, sub-system, and system monitoring tools; foundational data interfaces; performance analysis tools, and more. They have substantial expertise and multiple years of experience in all aspects of HPC tool development, including developing for high-fidelity data concurrent and evolving types of processors, accelerators, filesystems, high speed networks; developing interactivity with a variety of software stacks and resource managers; developing interoperability among tools; and developing performance and tool output visualizations.
