Running WRF on Derecho

Hello,

I am running WRF model on Derecho. I want to know how can I use the optimum resources while submitting my batch job, i.e., what choices should I make for the number of nodes, ncpus, mpiprocs and ompthreads? My domains have grid spacings of 9 km and 3 km and I plan to run the WRF for 5 days.

Regards,
Shreyas
 
Hi Shreyas,
The choices you make, regarding compilers, typically comes down to the size of your domain. Take a look at Choosing an Appropriate Number of Processors for best practices for that. We don't have any documented tests regarding openmp on Derecho yet, though others on this forum may be able to offer some hints, if they have experience with it.
