About this document
How do I run a job on a HPC machine?
Sharing Resources
- Many other users using the cluster — resources must be shared:
- CPU cycles:
-
- computational jobs must be "submitted" to the cluster
batch system, e.g., LFS, PBS or SGE;
- sit in a queue until one or more compute nodes are allocated;
- must never be run on the head node.
- File space:
-
- home directory, plus
- scratch space
. . . disk quotas. . .
