BlueBEAR GPU Service

There are some applications that benefit from GPU computing. These applications will usually use the CUDA libraries to take advantage of GPU computing.

Access to the BlueBEAR GPU Service

To request access to the GPU nodes please contact us through the IT Service Portal. We may ask for more information about the types of applications you are looking to use on these nodes prior to granting access to this service.

Using the BlueBEAR GPU Service

To use one of the gpu nodes, add

#SBATCH --qos bbgpu
#SBATCH --account [projectname]
#SBATCH --gres [gpu]

to your job submission script, where [projectname] is a project that has access to the GPU service; and [gpu] is the type of GPU you wish to use in your job - specified in the form gpu:p100:1 to request one NVidia P100 per node in your job (see the list of available GPU nodes below). If, when you submit a GPU job, you receive an error message of

sbatch: error: Batch job submission failed: Invalid qos specification

then either you are not a member of a project that has access to the GPU service or the project you specified does not have access to the GPU service.

Available GPU nodes

In the bbgpu QOS we have:

  • Two P100 nodes each with: 
    • 2 x 10 core broadwell (X86_64) CPUs
    • 1 x NVIDIA Tesla P100, 16GB GPU
    • 120 GB system memory
    • Request 1x P100 using gpu:p100:1
  • One A100 nodes each with:
    • 2 x 28 core icelake (X86_64) CPUs
    • 2 x NVIDIA Ampere A100-40, 40GB GPUs
    • 500 GB system memory
    • Request 1x A100 using gpu:a100:1
  • One A30 nodes each with:
    • 2 x 28 core icelake (X86_64) CPUs
    • 2 x NVIDIA Ampere A30, 25GB GPUs
    • 500 GB system memory
    • Request 1x A30 using gpu:a30:1

Software

We have installed a range of applications on the BEAR GPU nodes, but the software available on the different GPU types does vary and you may have to direct your job to the correct GPU type for the version of an application you wish to use. On the BEAR Applications site the available architectures for a specific version of an application will include details on which GPUs the software has been installed for.

If the software you are looking to use is not available, or not available on the nodes you wish to use it on, then please open a Request New BEAR Software to discuss this with us. However, we usually will only make available the newer versions of an application on the newer (A100-40 or A30) GPUs.

Baskerville and Sulis

Where the GPU resources available on BlueBEAR are insufficient you may be eligible for access to Baskerville or Sulis. Please see the Tier2 HPC information for more details on applying for access to Baskerville or Sulis.
