In HIHE01-1, "Evaluate a PathForward/Facilities memory-relevant performance study/analysis," we conducted a focused study on the performance differences between HBM2 and HBM3 as revealed through execution of representative benchmarks. We used measurements on an existing many-core system, Knight's Landing (KNL), to calibrate simulator settings, and then performed Structural Simulation Toolkit (SST) simulations of KNL-like CPUs that access future high bandwidth memories. This report documents our findings.
