Dear All, I would like to know if there is any plan to port the Einstein Toolkit to GPUs. This is something that we may also discuss at the next Einstein Toolkit workshop if there is time.
The reason I'm asking is that in Italy, CINECA (part of the EU HPC consortium) just bought its new HPC cluster and it is completely GPU based (Marconi100, https://www.hpc.cineca.it/hardware/marconi100, currently ranked in the top 10 of the fastest supercomputers in the world).
Speaking with people at CINECA, I was informed that HPC-Europe is moving to GPU and, while cpu codes will be still supported for the next 5 years (with some of the new clusters still having a limited number of nodes for cpu codes), the plan is to move to 100% GPU clusters at the EU level. I was indeed told that the latest 3 HPC clusters bought by HPC-Europe are GPU clusters. The next Italian HPC machine will also be a GPU cluster, with a limited number of cpu nodes (they estimate ~3500 nodes with GPUs and ~1000 nodes with cpus).
Thanks, Bruno
