Mihael,

In this setup I am using nodeGranularity=16, jobsPerNode=16, and maxNodes=16. The SGE submit file could request anywhere between 16 and 256 cores in multiples of 16. 

When I run catsn with -n=2, count is 16. 
When I run catsn with -n=20, two SGE submit scripts get created, each with count=16. 

Should count=32 in the second case? Am I misunderstanding what 'count' is? Is there any way to get the exact number of applications?

Thanks,
David
