--------* | | | | | | | | | ---neve---- | | | | | | | | | --------*. neve is a microbenchmark that distributes a graph (real-world or synthetic) across processes and then performs variable-sized message exchanges (equivalent to the number of ghost vertices shared between processes) between process neighbors and reports bandwidth/latency. Further, neve allows options to shrink a real-world graph (by a percent of ghost vertices shared across processes), study performance of message exchanges for a specific process neighborhood, analyze the impact of an edge-balanced real-world graph distribution, and generate a graph in-memory. neve reports bandwidth/latency, and follows the best practices of existing MPI microbenchmarks. We require the total number of processes to be a power of 2 and total number of vertices to be perfectly divisible by the number of processes when parallel RGG generation options are used. This constraint does not apply to real world graphs passed to neve.
