Switch branches/tags

Name already in use

A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

* Fix misdocumented IOR END for IOR STOP.
The prose mentions IOR END, which is not actually a thing, as I gather from src/parse_options.c.
Also, the words are case-insensitive, which might be welcomed by some people preferring
lowercase aesthetics;-)  If they are treated that way (strncasecmp()), they should be documented
that way. For brevity, I did not repeat that for RUN, but one could do that, too.
* Explicitly clarify parser behaviour also for RUN.
All of the control words are compared via strncasecmp(). Be vocal about that. The documentation
should not be pretty, but precise.
* fix syntax and grammar

A space too much messes up the rst list, and a dot each was missing for English grammar.

HPC IO Benchmark Repository Build Status

This repository contains the IOR and mdtest parallel I/O benchmarks. The official IOR/mdtest documentation can be found in the docs/ subdirectory or on Read the Docs.


  1. If configure is missing from the top level directory, you probably retrieved this code directly from the repository. Run ./bootstrap to generate the configure script. Alternatively, download an official IOR release which includes the configure script.

  2. Run ./configure. For a full list of configuration options, use ./configure --help.

  3. Run make

  4. Optionally, run make install. The installation prefix can be changed via ./configure --prefix=....


  • Run make check to invoke the unit tests.
  • More comprehensive functionality tests are included in testing/. These scripts will launch IOR and mdtest via MPI.
  • Docker scripts are also provided in testing/docker/ to test various distributions at once.
