Dear Graziano and James,

With RegCM-4.3.5.4 I also faced the problem when submitting the job for 32 cores in 4 nodes. The regcmMPI compiled by ifort and openmpi-1.6.3 dumped to single node (first node), showing the load increases on the node and finally aborted.

To solve the above problem, I tried back to RegCM-4.3.5.2 and found it is working properly on 4 nodes.

But there are other issues for choosing schmes:

For larger domain the model stops after 1 year with icup=4, icup=99 and icup=2 options.

Pls have a look on these issues

With regards

G Faruq

Dear RegCNET,

I have been running several test simulations with RegCM4 using mpi. However, in many cases, the simulation never even started and aborted very early on.

The people in charge of our computer cluster suggested the use of a sleep command, and in some cases it seemed to help (especially when a larger number of processors was used).

I haven't yet managed to solve this problem. At the moment, I just try the simulation again. My colleagues have not yet identified the source of the problem. So I am sending this email, just in case anyone has encountered such errors before.

I am attaching some of these errors.

Regards,
James
