Tuning & Scaling Workshops for JUWELS Booster Module

Two hands-on workshops early in 2022 will be dedicated to analysing, tuning, and scaling the HPC application codes of JSC users on the quad NVIDIA A100 GPU compute nodes of the JUWELS Booster module.

The first workshop to be held will be the 41st VI-HPS Tuning Workshop organized by JSC and RWTH Aachen University from 7 to 11 February 2022. It will provide an introduction to performance measurement and analysis of application codes executed on the JUWELS Booster module, particularly multi-node/multi-GPU application executions. Based on examples provided, participants will be given support to help them progress to working with their own application codes. Applicants are therefore encouraged to prepare suitable application test cases. Detailed information can be found at https://www.vi-hps.org/training/tws/tw41.html.

From 7 to 11 March 2022, a Tuning and Scaling Workshop will then take place dedicated to improving performance and the scaling of applications using multiple GPUs, with opportunities to scale to the full complement of over 3600 GPUs connected by the high-speed InfiniBand network in the JUWELS Booster module. Applicants for this workshop should be able to build and run their codes correctly on multiple quad-GPU nodes of the JUWELS Booster module and demonstrate the potential for improved performance and scalability – expertise that can be obtained from the preceding VI-HPS Tuning Workshop. Detailed information can be found at https://go.fzj.de/2022-jwb.

Both workshops will present state-of-the-art tools and techniques for efficient multi-GPU computing, combined with interactive hands-on sessions, with instructors and mentors from JSC, NVIDIA, and VI-HPS partners. They will be held as online training events requiring separate registration for those interested in taking part in both.
