While true bear in mind their are limits on the number of cores that it 
might be quite easy to pass on a high end multi CPU AMD machine :-)

See question 5.3

https://www.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.pdf

192 is the largest tested limit for the number of cores and there is a 
hard limit at 1536 cores.

 From memory these limits are lower in older versions of GPFS.So I think 
the "tested" limit in 4.2 is 64 cores from memory (or was at the time of 
release), but works just fine on 80 cores as far as I can tell.
