nodesSort { PROC LOAD_1 LOAD_5 LOAD_15 PROC+LOAD NONE } [nodes]

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.

This only comes into play, if the user does not define a sorting strategy explicitely via PSI_NODES_SORT. Be aware of the fact that using a batch-system like PBS or LSF *will* set the strategy explicitely, namely to NONE.

overbook [ 0 1 ] [nodes]

Define if this nodes shall be overbooked upon user-request (if flag is true) or if overbooking should be denied at all (false).

starter [ 0 1 ] [nodes]

Define if starting jobs from this nodes should allowed (flag is true) or denied (false).

runjobs [ 0 1 ] [nodes]

Define if running tasks on this nodes should be allowed (flag is true) or denied (false).

rdpmaxretrans val [nodes]

Set RDP protocol's maximum retransmission count.

exclusive [ 0 1 ] [nodes]

Set flag marking if this nodes can be requested by users exclusively to bool. Relevant values are 'false', 'true', 'no', 'yes', 0 or different from 0.

pinprocs [ 0 1 ] [nodes]

Set flag marking if this nodes will use process-pinning to bind processes to cores. Relevant values are 'false', 'true', 'no', 'yes', 0 or different from 0.
