The Hedin computing cluster
Hedin is the computing cluster of the PMC group of the CPHT laboratory funded as part of the ERC Consolidator CORRELMAT. All the nodes of the cluster are interconnected by a high speed QDR InfiniBand network.
Important
In 2022, all Hedin nodes have been integrated into the Cholesky cluster on a dedicated QDR infiniband network.
User resources
- 2 login front-end nodes (DNS Round Robin for load sharing or fault tolerance) of Cholesky cluster
- A parallel file system BeeGFS to access only to HOME directories and Software Modules by Cholesky ethernet network
- A network file system NFS to access to WORK directories : 88 TB of usable space
- A Intel Q-Logic InfiniBand QDR (Quad Data Rate) interconnection network 40Gb/s
