Summary
The image shows ClusterCockpit measurement results for an application that is executed with multiple scaling configurations. It is executed with four different configurations on 1 core, 128 cores (1 node), 256 cores (2 nodes) and 512 cores (4 nodes). Three metrics are show for every case: Flops per core, memory bandwidth per socket and transmitted network packets per node. The plots show how with increased number of involved cores and nodes the performance degrades and the communication overhead increases.
