UL HPC Clusters
The UL HPC platform is composed of 4 clusters:
Each cluster is organized according to the following generic scheme:
As can be seen, our clusters consist of:
- a front-end server access-*.uni.lu that serves as an interface and access point to the cluster
- an adminfront server, which is only relevant for the management team. It hosts as many VMs (under the Xen hypervisor) as there are services to operate the cluster
- a shared storage area, based on NFS and, in somes cases, Lustre, which permit the sharing of data across the cluster
- a set of computing nodes which can be reserved and used for a given period of time by the users of the cluster via the OAR batch scheduler.
- a fast interconnect topology that establishes high performance communication between the cluster elements
All clusters feature Intel processors, under two micro architectures:
Each computing node runs the Debian Linux operating system, version 7 (Wheezy) and you’ll have to interface with them by using the command line.
Thus, you are more than encouraged to become familiar - if not yet - with Linux commands. We can recommand the following sites and resources:
