¹ This blog is an experiment. We want to share bits and pieces of our work; the reports we write, the presentations we hold, or the little discoveries we make, or even some first, water-testing investigations; and all the rest. It’s a documentation of what we do. Little bits of science, collected in the open, and sometimes even not that little.

A few months ago, we extended the JURECA Evaluation Platform ¹ at JSC by two nodes with AMD Instinct MI250 GPUs (four GPUs each). The nodes are Gigabyte G262-ZO0 servers, each with a dual socket AMD EPYC 7443 processor (24 cores per socket, SMT-2) and with four MI250 GPUs (128 GB memory).
