And it's so painful for me since my workload is completely memory bandwidth bound but does not scale across multiple sockets, much less multiple nodes.
96 cores per socket? ๐
12 channels of ram per socket? ๐คฉ
DDR5-4800? ๐ซ
Just curious, but what workload doesn't scale across multiple sockets? Gaming?
A specialized computational fluid dynamics program. And nominally CFD is great to scale across many sockets/systems but it seems this particular program wasn't written to be able to do that.
