This repo includes the benchmarking templates for understanding and tuning HDF5 performance on three production supercomputers: summit at ORNL, cori at LBL and theta at ANL.

ior/ includes the modified source code of IOR, which exeplicitly fsync() I/O writes for POSIX, MPI, and HDF5, with option "-e". And fsync() during file close in default.

summit_/ include all the IOR templates designed for and runing on summit.
