Table 4. Multicast debug flags freeOnSuspend [ 0 1 ] [nodes]
Switch the freeOnSuspend flag on or off 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.
This flag can be set persistently via the freeOnSuspend option within the ParaStation configuration file parastation.conf(5).
handleOldBins [ 0 1 ] [nodes]
Switch the compatibility flag for applications linked against version 4.0.x of ParaStation on or off on the selected nodes.
