Hardware Facilities
The HPC clusters are hosted in a Tier-2 compliant data centre. The live statistics of the clusters can be seen here. If you need to get an account on the cluster you would need to fill and submit HPC Resources Request Form. The instructions and complete details of the clusters can be found in Manual for using HPC Resources.
The following clusters are currently providing HPC services:
