wrf takes a long time to run


New member
Dear All,

I am new to the forum, and I have questions to ask you, this is my first post. My name is Lucas and I am from Argentina.

I have compiled the WRF model on a server and in the first tests I noticed considerably lower performance than the same model has on other of our servers, which catches our attention since the latter are older and have fewer resources.
When I run a run no error appears but it takes a long time to finish. Could the problem be in the MPI library? I use mpich and the processor is an AMD Ryzer 9.

Change the MPI library.
I replaced Mpich with Open MPI to test, however I didn't get better results. Everything continues to work the same way.

any suggestions?
Do you have compilation - and possibly runtime - logs for both on the new server as well as an example older server? Noting any significant discrepancies between those two should give a solid starting point as to what might be the issue.
