Sumario:As new HPC technologies appear, small local research laboratories face uncertain options when building hybrid clusters. Users may find difficult to choose among several multicore products with different core densities. Our research project intends to build knowledge about HPC problems to be able to help local researchers. We analyze NUMA hardware for use in clusters and present a case study. We run a well-known benchmark over MPI and advise the user depending on application features.
