I have seen a few papers around, but does anyone have comments on how to optimize ether lustre or abaqus to use lustre for scratch? I see reads coming in at only 20MB/s and IO Wait gets quite high on the client. I know this is probably not enough information, but is there any knobs people have twisted on their own systems for this that I can be informed on?
