The value part of each line either is a single word or an expression enclosed by single or double quotes. The expression might contain whitespace characters. If the expression is enclosed by single quotes, it is allowed to use balanced or unbalanced double quotes within this expression and vice versa.

This command might be used for example in order to set the PSP_NETWORK environment variable globally without the need of every user to adjust this parameter in his own environment.

freeOnSuspend { true yes 1 false no 0 }

If the argument is one of yes, true or 1, suspending a task by sending the signal SIGTSTP to the logger will handle all resources (CPUs) currently claimed by this task as free.

If the argument is one of no, false or 0, ParaStation will not claim resources as free after sending

SIGTSTP.

handleOldBins { true yes 1 false no 0 }

If the argument is one of yes, true or 1, compatibility mode for applications linked with ParaStation version 4.0 up to 4.0.6 will be enabled. Keep in mind that this behavior might collide with the freeOnSuspend feature.

If the argument is one of no, false or 0, ParaStation will disable compatibility mode.

UseMCast { true yes 1 false no 0 }

If the argument is one of yes, true or 1, keep alive messages from the ParaStation daemon psid(8) are sent using Multicast messages.

If the argument is one of no, false or 0, ParaStation will use it's own RDP protocol for keep alive messages. This is the default.

PSINodesSort { PROC LOAD_1 LOAD_5 LOAD_15 PROC+LOAD NONE }

Define the default sorting strategy for nodes when attaching them to a partition. The different possible values have the following meaning:

PROC

Sort by the number of processes managed by ParaStation on the corresponding nodes

LOAD_1

Sort by the load average during the last minute on the corresponding nodes

LOAD_5

Sort by the load average during the last 5 minutes on the corresponding nodes

LOAD_15

Sort by the load average during the last 15 minutes on the corresponding nodes

PROC+LOAD

Sort conforming to the sum of the processes managed by ParaStation and the load average during the last minute on the corresponding nodes

NONE

Do not sort at all.
