Welcome to the High-Performance Computing (HPC) wiki

The High-performance Computing (HPC) cluster is part of workpackage 5 (infrastructure) of the Research ICT program of the UMC Utrecht and aims to provide high-performance computing power to researchers within the UMC Utrecht.

The first part of the wiki introduces the HPC cluster to those of you who may be interested to join. Take your time and have a look around.

The second part of the wiki contains useful practical information for users of the HPC cluster.

Inspired by a slight mishap yesterday, we'll be limiting the maximum number of jobs any user can queue simultaneously to 100.000.

Thursday, 6th Feb 2014

The number of slots per queue has been adjusted, like discussed on the HPC Usercouncil meeting. The new settings are:

veryshort: 12 slots per node
short: 9
medium: 7
long: 4
verylong: 1

/home and /hpc/local are now served from a different server. This should improve the interactive responsiveness when the cluster is heavily used.

If you notice anything different or unusual, please notify us.

General information

The HPC cluster currently consists of 56 compute nodes (672 cores, 7TB working memory) and 160TB of HPC storage. A dedicated Linux administrator is funded by the research ICT program. In addition, the program subsidizes the HPC storage capacity.

Participating groups. Currently, fifteen research groups are actively using the HPC cluster.

HPC user council. To steer future directions of the HPC infrastructure together with the participating research groups, a HPC user council has been setup. We aim to meet four times a year to discuss the usage of the HPC cluster as well as new developments.

How to get involved. Research groups can participate by funding the hardware required for their own computational needs. HPC storage capacity can be rented on a per Terabyte, per year basis. For testing purposes and/or trying out the HPC infrastructure, free trial accounts can also be arranged that have (limited) access to the HPC resources, contact us if you are interested.

Contact details

The working team HPC is responsible for setting up and maintaining the HPC infrastructure, as well as for helping out with HPC related user questions. For details and contact information, go here.
