[Wien] using wien2k on shared Lustre file system

[Katherine Reed]

Hello,

I am hoping to run wien2k on Stampede2 at the Texas Advanced Computing Center (TACC). The system administrators are concerned because tests of wien2k on the system have shown it to be problematic because it does data exchange via the shared Lustre file system and this can easily crash the file system, which is not designed to handle many, frequent reads and writes by many processes. Does anyone have a suggestion to work around this issue? Is there a solution other than to change systems?

Thanks,
Kate Reed
