Chapter 3. The Cray T3E system 29
The T3E file systems at CSC are located on striped FiberChannel disks re-
siding in one GigaRing, which is attached to a Multi Purpose Node (MPN).
The total disk capacity is over 300 GB. Most of the space is allocated for
paging (swapping), $TMPDIR and $WRKDIR.
3.10 Resource monitoring
The most useful commands for viewing the global configuration and
status of the Cray T3E system are grmview and top.
The grmview command displays information on the Global Resource
Manager (GRM) regarding the current PE configuration (PE map), appli-
cations currently running on the PEs and applications waiting to run on
the PEs.
Here is an extract of the output of the command grmview -l:
