Giovanni, I have clients in Australia that are running AMD ROME
processors in their Visualisation nodes connected to scale 5.0.4
clusters with no issues. Spectrum Scale doesn't differentiate between
x86 processor technologies -- it only looks at x86_64 (OS support
more than anything else)
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.
