Process mapping on any topology with TopoMatch

Process mapping (or process placement) is a useful algorithmic technique to optimize the way applications are launched and executed onto parallel machine. By taking into account topology of machine affinity between processes, helps reducing communication time whole application. Here, we present TopoMatch, generic versatile library algorithm address placement problem. We describe its features characteristics, report different use-cases that benefit from this tool. also study impact factors: sparsity input matrix, trade-off speed quality procedure as well uncertainty (noise) input.
