WebIOR leverages the scalability of MPI to easily and accurately calculate the aggregate bandwidth of an (almost) unlimited number of client machines. In addition, IOR can utilize the POSIX, MPI-IO, and HDF5 I/O interfaces. The main downside of IOR is that you need to have a working version of MPI installed on your machines (and know how to use it). WebThe Intel MPI Benchmarks perform performance measurements for point-to-point and global communication operations for a range of message sizes. The generated benchmark data characterizes the performance of a cluster system, including node performance, network latency, and throughput efficiency of the MPI implementation used.
