About Sunbird

Sunbird is located in Swansea University. It is available for Swansea and Aberystwyth users of Super Computing Wales. Bangor and Cardiff users should use the Cardiff Hawk system.

Guest users from other institutions will be allowed access on the basis of the project & institutions they are working with.

System Specification:

  • 126 nodes, totalling 5,040 cores, 48.384 TBytes total memory
    • CPU: 2x Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz with 20 cores each
    • RAM: 384 GB per nodes
    • GPU: 8x Nvidia V100 GPUs
    • Storage:
      • 808TB (usable) scratch space on a Lustre filesystem
      • 231TB of home directory space on a Lustre filesystem


The available compute hardware is managed by the Slurm job scheduler and organised into ‘partitions’ of similar type/purpose. Jobs – both batch and interactive – should be targeted at the appropriate one. Limits on the partition are just defaults, we can provide access to different limits, for example to enable array jobs a higher number of submitted jobs maybe required. Please contact support if required.
