Might I also suggest putting your IOR issue here? It's the accepted standard of benchmarking tools, so many, many people here will be familiar with it. No guarantee of help, but it might be worth a shot.<br>

<div class="PlainText">IIRC iozone does not use MPI, and has it's own config files, which can get<br>
complex. I found running something like xdd was more reliable and easier<br>
to organize, though a little more care needs to be put into evaluating the<br>
final results. IOR is a much simpler and straightforward tool to use on a<br>
cluster.<br>
