The aim of this project was to ensure that:

  • ARM servers work harmoniously with accelerators such as GPUs
  • Any shortcomings are understood, documented and reported to vendors
  • ExCALIBUR and the wider UK research community has access to an ARM-GPU testbed

The project put into place an ARM+GPU testbed system based on the NVIDIA ARM HPC Developer Kit. This included four nodes with specifications as detailed below, incorporated into the University’s existing ARM Catalyst system:

  1. GIGABYTE G242-P32, 2U server
  2. 1x Ampere Altra Q80-30 (Arm processor)
  3. 512G DDR4 memory
  4. 6TB SAS/ SATA 3.5″ storage
  5. 2x NVIDIA A100 GPU
  6. 2x NVIDIA® BlueField®-2 E-Series DPU

The project included Research Software Engineering (RSE) effort for the porting, benchmarking and development of existing codes and creation of digital assets including progress reports, white papers and how-to documents, as well as software enhancements and modification.
