cluster
the command uses the result of the pbsnodes -a command and graphically displays the information, showing the occupied cores, e.g.:
core

The above result shows that:
- node n1 is occupied by job 88182 using 48 cores,
- nodes n2, n3 and n4 are occupied for a total of nine jobs (three jobs per each node, each of 16 cores),
- node n5 is occupied by two jobs (each of 16 cores),
- node n7 is turned off (tzw.
down); this occurs when you can not communicate with the node due to shutdown or suspension, - node n10 is occupied by one job (1 core),
- node n11 is excluded from the queuing system co-called
offline) - nodes n12 and n13 are occupied by one job that uses 64 cores on each node,
- nodes n6, n8, n9 and n14 are not used.
cluster command are an alias to the klaster command.
