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.

The test cases are extended to some other known HPC GPU hardware platforms: the build parameters and runtime parallel configuration are now machine-dependent, also it can be CUDA instead of HIP.
