Overview

The GPU partition of Setonix is made up of  192 nodes, 38 of which are high memory nodes (512 GB RAM instead of 256GB). Each GPU node features 4 AMD MI250X GPUs, as depicted in figure 1. Each MI250X comprises 2 Graphics Complex Die (GCD), each effectively seen as a standalone GPU by the system. A 64-core AMD Trento CPU is connected to the four MI250X with the AMD InfinityFabric interconnect, the same interconnection between the GPU cards, with a peak bandwidth of 200Gb/s—more information at Setonix General Information.
