Research output: Book/ReportOther report


LAPI is an IBM-specic communication library that performs single-sided operation. This library was well profiled on Phase 1 of the HPCx system. Phase 2 of HPCx is now in service, using newer hardware and software than Phase 1. This report aims to capture the performance characteristics of LAPI, compare it to MPI's performance, and investigate whether we can improve performance by tuning the default runtime environment.
