IRMACS High Performance Computation

ClusterOne of the IRMACS Centre's main focus is the support of computational tools in the support of intersdisciplinary research. As part of this support IRMACS provides its user community with access to two key computational resources:

  • A dedicated computational cluster
  • A dedicated resource allocation on Compute Canada infrastructure

IRMACS Computational Cluster

A dedicated computational cluster. The IRMACS computational cluster is a ten blade server with each blade consisting of 2 Quad Core Intel Xeon CPUs. Each blade has 16 GB of memory (2 GB/core) for a total of 80 CPUs and 160 GB of memory. Data storage on the cluster is provide by a 2 TB Raid disk array. The cluster is running 64-bit Linux. A number of commonly used software packages are installed on the IRMACS cluster, and open source software or software purchased by researchers can be installed on request. For more information on utilizing the IRMACS computational cluster, including information on the software installed and how to submit jobs, please refer to the IRMACS computational cluster support documentation.

Note: As of June 16, 2014 the IRMACS compute nodes have been integrated with the RCG Colony Cluster. As with the IRMACS Resource Allocation on Compute Canada, IRMACS users will have priority access to 80 cores on the Colony Cluster. This migration is necessary for two main reasons: it helps us (IRMACS and RCG) minimize support time by not maintaining two completely separate clusters as well as allowing IRMACS to retire some of its aging hardware that was required to keep the IRMACS cluster running. The colony cluster is run in much the same way as the IRMACS cluster was, so not much should need to change in how you use the system.

With that said, some changes will be necessary when we make the switch over. For documentation on what you will need to change, please see the IRMACS Cluster to Colony Cluster migration documentation.

If you have questions or concerns, please email

General purpose documentation in using the colony cluster is available here.

IRMACS Compute Canada Resource Allocation

In order to support its users in the use of large scale computational science, IRMACS maintains a Resource Allocation on WestGrid/Compute Canada infrastructure. The IRMACS Compute Canada resource allocation provides IRMACS users with priority access to 200 core years of computation and 20 TB of backed up storage. For more information on using the IRMACS Resource Allocation on WestGrid/Compute Canada infrastructure please refer to the IRMACS Compute Canada support page.
