Bede (Tier 2 GPU cluster)

Bede is a EPSRC-funded ‘Tier 2’ (regional) GPU-equipped HPC cluster. The system is available for use by researchers from N8 Research Partnership institutions (Durham, Lancaster, Leeds, Liverpool, Manchester, Newcastle, Sheffield and York).

NB the system was previously known as NICE-19.

Suitable workflows

This system is particularly well suited to supporting:

  • Jobs that benefit from distributing work between multiple GPUs and possibly multiple nodes.

  • Jobs that require much movement of data between CPU and GPU memory.

  • In particular deep learning and machine learning workflows that meet either of the above criteria.

Status

Academics/researchers can apply for access to the system (see Further Information) but note that some aspects of the system plus the registration and support mechanisms are still being refined.

Noteworthy features of the system

  • 32x GPU nodes (IBM AC922 nodes) each with

    • 2x IBM POWER9 CPUs

    • 2x NVIDIA V100 GPUs per CPU

    • Each CPU is connected to its two GPUs via high-bandwidth (150GB/s), low-latency interconnects (NVLink), which helps if you need to move lots of data to/from GPU memory

    • 512 GB RAM

  • 4x ‘inference’ nodes (IBM IC922 nodes) each with

  • 6x NVIDIA Grace Hopper Superchip (GH200 480GB) nodes each with

    • 1x NVIDIA Grace CPU (72 Arm Neoverse V2 cores)

    • 1x NVIDIA H100 96GB GPU

    • The CPU and GPU are connected via 900 GB/s NVLink-C2C interconnect, which helps if you need to move lots of data to/from GPU memory or over-subscribe the GPU

    • 480 GB LPDDR5X RAM

  • High-bandwidth, low-latency networking between nodes (100 Gb/s EDR Infiniband)

  • High-performance parallel file system (Lustre)

  • Slurm job scheduler
