For a science fair project I am comparing the performance of MPI and PVM on GPU clusters. The biggest problem I have is finding benchmarking software for PVM. Linpack is the most used benchmarking software, and from there I have gone on to find Scalapack, a set of libraries which has the same type of functions as Linpack, but supports both PVM and MPI. From my understanding, Linpack, Specifically HPL , Is a set of functions along with a program which utilizes them for benchmarking. Scalapack, on the other hand, appears to be only the funtions, with no program. Does anyone know how to use Scalapack as a cluster benchmark that measures performance, in flops if possible?
