master [nodes]
Show the current master on the selected node(s).
The master node's task is the management and allocation of resources within the cluster. It is
elected among the running nodes during runtime. Thus usually all nodes should give the same
answer to this question. In rare cases - usually during startup or immediately after a node failure
- the nodes might disagree on the elected master node. This command helps on identifying these
rare cases.
freeOnSuspend [nodes]
Show the freeOnSuspend flag on the selected nodes.
The freeOnSuspend flag steers the behavior of the resource management concerning suspended
jobs. Basically there are two possible approaches: Either the resources used by the suspended
job are freed for other jobs (this is done, if the flag is set to 1) or they are kept occupied in order
to preserve them exclusively for the time the job continues to run (this is the behavior as long as
the flag has the value 0).
Since the master node does all the resource management within the cluster, only the value on this
node actually steers the behavior.
handleOldBins [nodes]
Show the compatibility flag for applications linked against version 4.0.x of ParaStation on the
selected nodes.
nodesSort [nodes]
Show the default sorting strategy used when attaching nodes to partitions.
Since the master node does all the resource management within the cluster, only the value on this
node actually steers the behavior.

runjobs [nodes]
Show if the selected node(s) are allowed to run tasks.

rdpmaxretrans [nodes]
