Matrix has 952 typical processor cores when all nodes are connected. It turns out Matrix can have as many as 9,144 cores if it could utilize 4 nodes with GPUs, which themselves contain yet another 8,192 cores! However, these additional GPU-based cores require specialized programming and have are not to-date been made available to researchers via the cluster. Those cores have only been accessible to researchers accessing these specialized nodes provisioned as workstations (and thus not attached to the Matrix cluster.) |
