Overview

What is the CSF?

The CSF (aka Danzek) is a High Performance Computing (HPC) cluster (19,632 cores + 152 GPUs) at the University of Manchester, managed by IT Services for the use of University academics, post-doctoral assistants and post-graduates to conduct academic research.

• It is built on a shared model: the majority compute nodes are funded by contributions of funds to the system by University research groups; the cost of infrastructure such as login nodes, fileservers and network equipment is, for the most part, paid for by the University.
• Academics are encouraged to contribute financially to the CSF rather than purchase their own smaller HPC clusters. The funds are used to buy compute hardware which is pooled in to the system. You are then given a proportional share of the available throughput in the system. Please see the benefits of the CSF for details on why this model is better than buying your own hardware.
• The CSF is suitable for a variety of workloads. Small–moderate parallel jobs (2-168 cores), serial jobs (1-core), high throughput jobs (running many copies of the same application at the same time to process many datasets) and GPU jobs (using Nvidia v100 Volta, A100 Ampere and L40s Ada Lovelace GPUs) are all supported. The number of jobs you can submit to the system is not restricted. The time it takes to run all of your jobs depends on your available throughput – i.e the size of your group’s contribution to the system.
• There is also some limited “free at the point of use” resource available in the CSF funded by the University. Please contact us if you are interested in using this.

For groups wishing to run larger parallel HPC jobs (128-1024 cores) the HPC Pool provides another resource (4096 cores in total). A separate, per-project application process is required to use it. For convenience, the CSF software and file-systems are available on the HPC Pool and so we document that system within these CSF online docs.
