Can I have my IT Services home directory and/or shared file-stores mounted on Viking?
No. Due to the large number of nodes and high speed interconnect between them, the University filestores would not be able to handle the large read/write throughput that running jobs on Viking can reach.
We advise that you use tools like rsync to maintain file parity between Viking, external fileservers and your device's local disks. Group directories are available on Viking to reduce file and database duplication amongst research groups - to request such a directory (or if you would like further information) please contact firstname.lastname@example.org.
