lumi-g-test

lumi-g-test project is a set of C++ micro-benchmarks that helps to test several important harware and system software characteristics of the GPU partition of LUMI supercomputer (https://www.lumi-supercomputer.eu). The metrics that are estimated by micro-benchmarks are mostly related of data transfer bandwidth aspects. The benchmarks cover cross-node and intra-node data tranfsers using MPI library, host memory to GPU memory transfer bandwidth characteristics, GPU memory internal bandwidth.
