Our users did not use "-binding" parameter when they submit a job and  
I would like to set it with JSV script. We have a SGI UltraViolet 1000  
SMP (ccNUMA)  supercomputer which has this CPU topology:

The processes context switch is too high and we would like to use this  
automatic binding feaute to decrease it and speed up the jobs.
