2021 ALCF Computational Performance Workshop

2021 ALCF Computational Performance Workshop

Attend our virtual workshop to boost application performance and achieve computational readiness for INCITE and other ALCF allocation programs.

The 2021 ALCF Computational Performance Workshop will be hosted as an online-only event.

Join us May 4-6, 2021, for an experience designed to help you boost application performance and achieve computational readiness on ALCF systems. Participants will have an opportunity to:

  • Work with ALCF and industry professionals through collaborative online sessions
  • Participate in guided hands-on exercises
  • Benchmark and debug your application with exclusive reservations on ALCF computing systems
  • Learn how to improve utilization on Theta/ThetaGPU/Cooley and prepare for future ALCF computing resources
  • Explore advanced techniques and tools to enhance application performance and expand your data science skills
  • Prepare for a major allocation award (e.g., INCITE, ALCC, ALCF Data Science Program)

For questions or concerns, please email us at comp-perf-support@alcf.anl.gov
