RCE Podcast logoIn this RCE Podcast, Brock Palen and Jeff Squyres speak with Jonathan Dursi about his recent editorial entitled HPC is dying, and MPI is killing it. The article that spawned a lot of attention in good discussion for our community.

The idea that the people at Google doing large-scale machine learning problems (which involves huge sparse matrices) are oblivious to scale and numerical performance is just delusional. The suggestion that the genomics community is a helpless lot who just don’t know any better and need to be guided back to the one true path is no less so. The reality is simpler; HPC is wedded to a nearly 25-year old technology stack which doesn’t meet the needs of those communities, and if we were being honest with ourselves is meeting fewer and fewer of the needs of even our traditional user base.
