EPYC is EPIC!

👇 Thread by @HatemLtaief on accelerating RT calculations for giant telescopes

@AMD Rome leads the pack (including HBM based CPUs) in terms of sustained bandwidth for their code by fitting into LLC

#HPC #SC21

@HatemLtaief:
The return of #x86… Compress algebraically the operator, fit into LLC, and run at cache bandwidth speed. This turns out to nicely work on #AMD #Epyc processors, making #HBM based hardware jealous :-) #SC21 #HPC #astronomy https://t.co/ALhDWoTzVw

RT @HatemLtaief: @thoefler @ISChpc @top500supercomp @ProfMatsuoka @HPC_Guru @hpcnotes The mixed precision flavors of these FP arithmetics are important to consider for traditional #HPC apps.

Yes, lower precisions are not for #AI only :-)

Domain scientists have yet to realize that they have been over computing for ages. Some did! #astronomy #seismic #climate #CFD

RT @HatemLtaief: @HPC_Guru @graphcoreai @Microsoft @PatrickMoorhead Too bad for u @Microsoft :-), @graphcoreai IPU turns out to be much more than an #AI chip. It can also be used for #HPC apps in computational #astronomy and #seismic imaging. And it does actually pretty good: scoring 2Tflops/s & 1Tflops/s, resp. These are Level-2 #BLAS op! #SRAM https://twitter.com/HatemLtaief/status/1579557011909664768/photo/1
