This package defines automated performance tests for HPC systems using both synthetic and MPI-based application benchmarks. It is designed to easily compare results from different systems, system configurations and/or environments (e.g. compilers & MPI libraries).

This package defines automated performance tests for HPC systems using both synthetic and MPI-based application benchmarks. It is designed to easily compare results from different systems, system configurations and/or environments (e.g. compilers & MPI libraries). At present results are included for 2x systems, with comparisons of performance using InfiniBand and RoCE (RDMA over Converged Ethernet) interconnects.

The intended test matrix is shown below, marked with (A) where there is an implementation (possibly not finalised) for the `AlaSKA` system:
