XIREL: Standard Benchmarks for Numerical Relativity Codes
Tao, Jian; Allen, Gabrielle; Hinder, Ian; Schnetter, Erik; Zlochower, Yosef
This is the first in a series of technical reports from the NSF XiRel project which is developing the basis for a next-generation infrastructure for numerical relativity, based on the Cactus framework and the Carpet Adaptive Mesh Refinement infrastructure. In this report, we construct an initial set of weak scaling benchmarks for numerical relativity codes to measure the scaling and performance of adaptive mesh refinement on current supercomputers. Initial results are provided for these benchmarks with Cactus and Carpet, providing a basis for measuring and understanding performance gains in the future development of XiRel.
