The GPU cluster is provisioned with two filesystems mounted on all the GPU compute nodes as follows :

Filesystem            Size  Used Avail Use% Mounted on 
/dev/sda1              48G  8.0G   38G  18% / 
/dev/sda2              48G  180M   45G   1% /spare  
tmpfs                  12G     0   12G   0% /dev/shm  

**/dev/gpfs              12T   45G   12T   1% /GPU**  
**sn8-ib@o2ib:/lustre   7.9T  5.7G  7.5T   1% /LUSTRE ** 

The “/GPU” filesystem of 12TB is served by a set of four (4) GPFS NSD Servers in the storage cluster. This mount is shared between all the nodes (hn, cn1, cn2,cn3,cn4,cn5). System administrators should refer to the Wiki namespace on GPFS for configuration and operations procedures.

The “/LUSTRE” filesystem mount is a 7.9TB shared filesystem served by a Lustre cluster running on a single shared Lustre MDS/MGS, plus a set of 3 ODS servers, serving a total of 9 Lustre OST's (3 per ODS). System administrators can refer to the Wiki namespace on Lustre for configuration and operations prcoedures.
