The #MI250 is misleadingly marketed as "one chiplet GPU" with 13312C, 90TFLOPs & 128GB @ 3.2TB/s.

But it is not. The 2 GCDs are 2 separate GPUs with 64GB each, like a K80 dual-GPU but in a socket. One #GPU can't directly access the other's memory.

To use both GCDs, the software needs to be multi-GPU capable. For many algorithms this is very difficult and for some it is entirely infeasible. The desire for large unified memory is huge.
The #MI250 promises exactly that with "128GB", but delivers only half.

#Fugaku continues to hold the No. 1 position that it first earned in June 2020

It was co-developed by Riken and Fujitsu and is based on Fujitsu’s ARM A64FX processor

It uses Fujitsu’s Tofu D interconnect

#SC21: @HPC_Hyperion #HPC Market briefing (without the breakfast this time 😉 )

Despite Covid, #Fugaku single-handedly saved the HPC revenue numbers for 2020 - a billion dollars makes a difference!
@HPC_Hyperion .@HPE is the top #HPC vendor, followed by @DellTech

@Fujitsu_Global jumped due #3 due to #Fugaku - so this is their 15 minutes of fame :-)

@InspurServer & @lenovo make up the Top 5

I'm excited to share that our work on SARS-CoV-2 is now published in @NatureChemistry! I'm humbled to have led this effort and provide a brief summary below: nature.com/articles/s4155…
Millions of @foldingathome users pooled their resources to create the first #Exascale computer and generated the world's largest MD dataset, simulating nearly the entire SARS-CoV-2 proteome.
We were the first group to discover that the Spike protein has incredible conformational heterogeneity and can adopt an 'open' state that reveals many cryptic epitopes. Many nAbs have since been found to target these cryptic epitopes!

🚨#COVID19 PAPER ALERT🚨
With your help, F@h became the first #exascale computer, collected 100,000X more data than a normal paper, learned how the #Demogorgon evades our immune system, and discovered drug targets called ‘cryptic’ pockets (#FAHPockets)!
biorxiv.org/content/10.110…
With over a million people downloading F@h, we reached #exascale computing speed within weeks. This made us >5X faster than the IBM Summit supercomputer, the fastest traditional supercomputer in the world!
This newfound power enabled us to simulate every possible protein from the #SARSCoV2 virus in parallel. Together, we generated the largest dataset of protein dynamics in history. We’ve highlighted some of our exciting findings in this thread:
