IOR

IOR is a software used for benchmarking parallel file systems using POSIX, HDF5 or MPIIO 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.

What is new in this release:

• The modifications to IOR-2.10.1 extend existing random I/O capabilities and enhance performance output statistics.
