Conditions and Support


In order to be able to use the HPC infrastructure, you need to be officially affiliated with the UMC Utrecht or Utrecht University. This means that you either need to be employed by one of these institutes or you need to have a "gastvrijheidsverklaring". The responsibility to ensure that this is the case is up to the principal investigator of the individual research groups part of either the UMC Utrecht or Utrecht University.

By using the HPC infrastructure you also comply with the following policies:

  • You are familiar with the guidelines of scientific conduct set forth by the UMC Utrecht and/or Utrecht University.
  • If applicable, you are familiar with and comply with the latest legislation concerning patient-related research.
  • Patient-related research data can only be used on the HPC infrastructure after (pseudeo)anonymization so that samples cannot be easily traced back to individual subjects.
  • Compute capacity is available based on fair shares. Fairs shares are coupled to the number of CPU cores financed by a particular research group and provides a mechanism that prioritizes jobs from groups with many shares over those from groups with few shares. There is however no guarantee that the hardware financed by a research group is always available for that particular group.
  • Abuse of HPC infrastructure resources may result in termination of the user account.


Support for the HPC infrastructure is provided on a "best effort" basis. This means that we will do our utmost best to keep the infrastructure running at all times, but that we cannot and will not guarantee 100% up time and do not have 24/7 support. Support requests are taken care of during normal working hours (weekdays, 9.00-17.00) and you can expect us to reply within a day. During weekends and evenings, we do typically monitor support requests and respond if possible, but this depends heavily on the availability and willingness of our support team to do this during their free time. No guarantees about response times will be given and/or can be claimed about support requests made during the weekend or evening. If not handled during this period, they will be taken care of the next working day.

Support requests should be directed to

To avoid confusion, we also want to be clear on what we support:

  • Hardware support for Dell compute nodes if a valid hardware support contract with the hardware supplier is in place.
  • General Operating System maintenance (security updates, software fixes, monitoring and management).
  • Configuration, optimization, maintenance and monitoring of the queueing engine and available resources.
  • Configuration, optimization, maintenance and monitoring of the HPC storage system.
  • Configuration, optimization, maintenance and monitoring of the HPC submit hosts and master host.

In addition, we try to assist/advise on the following topics, but cannot guarantee that are able to provide a solution:

  • Compilation, installation and configuration of group-specific software packages.
  • Provide a solution for peakperformance clashes between groups.
  • Implementation, configuration and optimization of bioinformatics workflows/pipelines.
