ROMS on XSEDE systems

#1 Post by wilkin » Wed Jun 04, 2014 4:12 pm

Does anyone have any recent experience running ROMS on one of the XSEDE (https://www.xsede.org/home Extreme Science and Engineering Discovery Environment - the successor to TERAGRID) high performance computing systems?

I'd appreciate hearing any advice on what hosts have proven useful for running long, modest sized ROMS applications, and whether users encountered any particular difficulties building and running the model, and experience with the bandwidth to these hosts if there a large amount of data to return.

I'm looking at requesting an allocation on host "stampede" at UT Austin.

John,

No problem building ROMS on Stampede, and it's fairly fast (IfinityBand FDR, 16-processor/node Xeon E5 (sandy bridge),pretty good I/O hardware ).

Quota of /work directory is 1T. No limit writing on the purged-storage /scratch (7.5P).

However, the max runtime is only 48-hr. The other major downside is that under heavy-load, the wait could be long. It easily takes hours before the job gets running.
