Add my voice to what Ben said... 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.

I found running something like xdd was more reliable and easier to organize, though a little more care needs to be put into evaluating the final results. IOR is a much simpler and straightforward tool to use on a cluster. -Ben On 8/25/16, 4:53 AM, "lustre-discuss on behalf of Pawel Dziekonski" <[email protected] on behalf of [email protected]> wrote: >> I've recently encountered an issue with IOR and was wondering if >> there were any other file system benchmarking tools that can be used >> to test reads / writes to a lustre file system from multiple nodes. > >http://www.iozone.org/ > >P > >-- >Pawel Dziekonski <[email protected]> >Wroclaw Centre for Networking & Supercomputing, HPC Department >phone: +48 71 320 37 39, fax: +48 71 322 57 97, http://www.wcss.pl >_______________________________________________ >lustre-discuss mailing list >[email protected] >http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
