Hardware and Software Platforms

MARCONI100: IBM Power9 Linux modular cluster system: 
  • 2x16 cores IBM POWER9 AC922 at 3.1 GHz with 256 GB/node of RAM memory
  • 4 x NVIDIA Volta V100 GPUs per node, Nvlink 2.0, 16GB
The local HPC system MARCONI100 is the primary platform for the workshop and will be used for the hands-on exercises. Course accounts will be provided during the workshop to participants without existing accounts. Other systems where up-to-date versions of the tools are installed can also be used when preferred, though support may be limited and participants are expected to already possess user accounts on non-local systems. Regardless of whichever external systems they intend to use, participants should be familiar with the relevant procedures for compiling and running their parallel applications (via batch queues where appropriate).
