    Description

      The I/O performance test could be valuable as a tool to evaluate potential hardware for SKA (e.g. for vendors) but 1/ further work is required to make it reproducible, and 2/ specific metrics need to be set in stone.

      Scripting work has been done in PI6 but it was tested on only one platform (Grid'5000). Adapting the scripts to at least another platform is important to identify and fix platform-dependent features.

      Scripts also need to be expanded to gather and plot more metrics (currently just data transfer speed as reported by the test). Reproducing the plots from memo 102 could be a sensible goal for this if nothing better has been identified.

      Finally, key specific metrics need to be identified and set in stone in the scripts, so future runs of the benchmark can be compared.
