High Performance Computing Clusters

UCD Research IT provide a wide range of services to the UCD Research community in relation to the provisioning and use of High Performance Compute Clusters. The HPC environment is ideal for researchers who need access to substantial computing resources, allowing them to greatly reduce the time required to perform large scale calculations. We currently have 3 options for the use of HPC clusters:

Tier 1

Tier 1 is a national service and is allocated to user projects that range in size from small "Discovery" (Class C) projects to large multi-year "High Impact" (Class A) projects. Customers for this service may require PI level status. Further information on this service is available here.

Tier 2

In collaboration with ICHEC (Irish Centre for High End Computing) ResearchIT offers a HPC condominium service which allows users to run large parallel processing jobs via Further details on this service are available here. The software available on the fionn cluster is available to view here.

Tier 3

Tier 3 offers the use of either the Sonic or Matlab clusters which are both suitable for serial or loosely coupled jobs. These clusters are offered under both the Community and Shared Compute models. The Community model allows those customers who can offer funding to these clusters a higher priority level over other customers who are operating with more restricted budgets. Both clusters are administered and managed by ResearchIT at no cost to the customers using them. Further information is available here.
