Gearshift is the High Performance Computing Cluster for human subject data of the UMCG. This cluster allows you to analyze datasets containing large and/or complex data and allows you to make calculations that cannot be done on a regular computer, while complying with the rules and regulations regarding human subject data. The Gearshift cluster works with a scheduler system, which means that calculation-jobs are scheduled and performed automatically when it is your turn and capacity is available.
The key features of the Gearshift cluster
- Linux OS: CentOS 7.x with Spacewalk for package distribution/management.
- Completely virtualised on an OpenStack cloud
- Deployment of HPC cluster with Ansible playbooks under version control in a Git repo: league-of-robots
- Job scheduling: Slurm Workload Manager
- Account management: Local admin users+groups provisioned using Ansible.
- Regular users+groups in a dedicated LDAP for this cluster and provisioned either with Ansible playbook too or using info from federated AAIM.
- Module system: Lmod
- Deployment of (Bioinformatics) software using EasyBuild
Gearshift consists of various types of servers and storage systems. Some of these can be accessed directly by users, whereas others cannot be accessed directly.
The costs you have to pay for using the data storage and the Gearshift HPC cluster are determined by the amount of data you store. If you want to use the data storage you have to pay for the permanent storage (prm), automatic backup to tape is included in the price. If you want to perform HPC calculations you have to pay for the temporary storage (tmp) as well, this includes use of the compute facilities. For both the permanent and for the temporary storage the fee is 250 euros per terabyte (TB) of data storage per year. So if you want to use both storage and compute facilities you pay 500 euro per TB per year. Minimal amount is 1 TB for 1 year.
