Description
Alya [5] is a computational mechanics code capable of solving different physics. It has been extensively used in MareNostrum III (BSC’s Tier-0 machine), and it has been also used as a benchmarking code in PRACE Unified European Applications Benchmark Suite. In this document, Extrae will be used to collect and analyze performance data during an Alya simulation in a petaflop environment. As a result of the performance analysis using Extrae [2] [3], some potential improvements in Alya have shown
up, and if considered, exascale scalability could be achieved.
