limit

This command defines a limit into the current node. It is a means of providing simple load management by say limiting the number of tasks submitted to a specific server.
Typically you either define limits on suite level or define a separate suite to hold limits so that they can be used by multiple suites.
suite limits
limit sgi 10
limit mars 10
endsuite
suite obs
family limits
limit hpcd 20
endfamily
extern /limits:sgi
task t1
inlimit sgi
task t2
inlimit /obs/limits:hpcd
endsuite
