NFS
NFS (Network File System) is a network file-sharing protocol that allows the nodes of an HPC cluster to access remote directories as if they were local.
It is served over a fast interconnection InfiniBand (IB).
NFS at the moment is available on cluster XCRESCO with only a scratch space per user.
SCRATCH space, with high performances, large quota and a delete policy for older files and no backup. The file systems are local to ENEAGRID sites and they are not accessible directly over wide area. The environment variable name is
$PFS_SCRATCH1in the cluster and the link in the HOME is~/PFS/tmp. The file systems characteristics are:
