Programming Methods for Summit’s Multi-GPU Nodes

Programming Methods for Summit’s Multi-GPU Nodes (Presented by Jeff Larkin & Steve Abbott – NVIDIA)
Oak Ridge National Laboratory
Building 5200, TN Rooms A,B
November 5, 2018
9:00 AM – 12:00 PM (ET)

The Oak Ridge Leadership Computing Facility (OLCF) will host a workshop on programming methods for targeting Summit’s multi-GPU nodes. During the event, local NVIDIA representatives – Jeff Larkin and Steve Abbott – will demonstrate

  • how using jsrun (job launcher on Summit) can make the transition from a single-GPU-per-node system (e.g., Titan) to a multi-GPU-per-node system (e.g., Summit) simpler,
  • how this simple approach can lead to portability issues with other multi-GPU-per-node systems (and how to resolve such issues),
  • and how it’s possible to fully take advantage of Summit’s nodes with CUDA-aware MPI and GPU Direct.
