[ONLINE] Efficient multi-GPU and multi-node execution of AI applications and frameworks on the GPU nodes of Karolina supercomputer (EuroCC)

This half-day course is dedicated to learning how to efficiently use the GPU accelerated part of Karolina for Deep and Machine Learning.

Technical details of the GPU partition of Karolina supercomputer

The accelerated part consists of 72 servers and each of them is equipped with 8 GPU accelerators providing a performance of 11 PFlop/s for standard HPC simulations and up to 180 PFlop/s for artificial intelligence computations.

72 compute nodes with 2x AMD Zen 2 EPYC™ 7763 processors with 64 cores and 2.45 GHz and 8x NVIDIA A100 GPU accelerators, 40 GB HBM2.
