Figure 4: Hercules scalability curves based on measured performance on ALCF Blue Gene/Q (Mira), NSF Track 1 (Blue Waters) and XSEDE Track 2 (Kraken) systems. Benchmarking on Mira for this allocation was only completed for the strong scaling curve from 8K to 32K cores (using 32 processes per node). These initial results, though limited, indicate that Hercules will sustain the excellent scalability shown in other machines, for which the computational readiness of the code is well established.
