Hi all, I am currently running WRF-Chem 3.4, but I've also had this problem with regular WRF 3.4. I am running a 3 domain simulation (45, 15, 5km). On different occasions, varying from writing the hour 0 domain 2 output, up to the first actual time step, WRF just stops running. It does not give me an error, just one of the nodes says segmentation fault. This only seems to happen when running more than 64 processors. I am running using a PGI compiled version of WRF, and I do not believe it is a namelist or model issue, as the crash seems to happen differently at several different points in the model run. However, sometimes, although rarely, the run will actually finish to completion with more than 64 nodes.<br>
<br>Has anyone had this happen before, or possibly know of a way to fix it? I am using a computer center that I have to submit my run to, so it can get frustrating waiting almost a day for my run to start, only to have it fail within a few minutes. Any help would be greatly appreciated.<br>
<br>Thanks,<br>Chris<br>
