Interleaved-Or-Random Filesystem Benchmarking

The IOR software is used for benchmarking parallel file systems using POSIX, MPIIO, or HDF5 interfaces. It can be used for testing the performance of parallel file systems using various interfaces and access patterns. IOR uses MPI for process synchronization. It also includes scripts for simulating the I/O behavior of a number of parallel applications.
