Benchmarking with Supernovae: A Performance Study of the FLASH Code

Joshua Ezekiel Martin,
Catherine Feldman,
Alan Calder
et al.

Abstract: Astrophysical simulations are computation, memory, and thus energy intensive, thereby requiring new hardware advances for progress. Stony Brook University recently expanded its computing cluster "SeaWulf" with an addition of 94 new nodes featuring Intel Sapphire Rapids Xeon Max series CPUs. We present a performance and power efficiency study of this hardware performed with FLASH: a multi-scale, multi-physics, adaptive mesh-based software instrument. We extend this study to compare performance to that of Stony … Show more
