Build and migration update

22 June 2022: Over the past month, we have had to reprioritise the project due to staffing and contractor shortages.

The Nimbus development and system testing is now scheduled to be completed by the end of July, which is later than our original timelines.

Once Nimbus is fully built, we will start the phased migration of users onto the new cloud environment. This is scheduled to start in August. Find out more.

Working specifications


Nimbus is hosted on the powerful and highly scalable Microsoft Azure platform, which offers virtually unlimited on-demand HPC computing and storage to meet your specific research needs.

The cloud environment includes the Azure CycleCloud tool, which give you a simple way to configure workloads. It also lets you optimise and scale the HPC infrastructure to meet your evolving research needs. CycleCloud includes the open source Slurm workload manager.


  • 2 TB Home storage area allowing users to log in
  • 16 TB Campaign area used for storing data. 512 MiB/s bandwidth
  • 9 TB Scratch space for temporary compute storage. 576.00 MiB/s.
  • BUCS Home, i.e., the H Drive


Network fabrics

  • Mellanox EDR InfiniBand (100 Gb/sec or 200 Gb/s depending on the series)
  • VPN from Bath to Azure (Bandwidth: 1 Gb/s)

Software environment

  • Azure CycleCloud for automated configuration and management of the HPC environment
  • Slurm for cluster job scheduling
  • Modules environment for managing software and applications
