Dear Jody,
WRF is running well on serial option (i.e single interface) . I am running
another application HRM using OpenMPI , there is no issue with that and
application is running on cluster of many nodes. The wrf manual says the
following about MPI run:
I*f you have run the model on multiple pr
Could you re-enable the SL param (btl_openib_ib_service_level) for
RoCE? Jeff was kind enough to provide a patch to let me specify the
gid_index, but that doesn't seem to be working. To get RoCE to work
correctly (at least, on Nexus switches) I'll need to specify both a
gid_index and an IB servic

FWIW: I have rarely seen this to be the is
Yes, I tried to add MPI_Barrier and it didn't work. The output is the
same with the code without MPI_Barrier.
Any more thoughts?
Thanks!

Hi Ahsan, Jody
Just a guess that this may be a stack size problem.
Did you try to run WRF with unlimited stack size?
Also, does your machine have enough memory to run WRF?
I hope this helps,

Not sure if this was not your intended meaning (using "can not" instead of "did
not"), but did you try it?

Hi,
Thanks for the reply. But this can not solve the problem.
The output indicate that both nodes hang at the second MPI_Wait, and
no one can reaches the MPI_Finalize.

I think Bill is right. Here is the description for mpi_finalize:
This routine cleans up all MPI states. Once this routine is called, no MPI
routine (not even MPI_Init) may be called, except for MPI_Get_version,
MPI_Initialized, and MPI_Finalized. Unless there has been a call to
MPI_Abort, you mus
Try putting an "MPI_Barrier()" call before your MPI_Finalize() [*]. I suspect
that one of the programs (the sending side) is calling Finalize before the
receiving side has processed the messages.

Hi, Thank you for the reply.
However, using MPI_waitall instead of MPI_wait didn't solve the
problem. The code would hang at the MPI_waitall. Also, I'm not quit
understand why the code is inherently unsafe. Can the non-blocking
send or receive cause any deadlock?
Thanks!

Hi
At a first glance i would say this is not a OpenMPI problem,
but a wrf problem (though io must admit i have no knowledge whatsoever ith wrf)
Have you tried running a single instance of wrf.exe?
Have you tried to run a simple application (like a "hello world") on your nodes?

Hi Ralf,
I've tested spawning with the OpenMPI 1.5 release but that fix is not there.
Are you sure you've added it ?
Thank you,

Hello,
I an stuck in a problem that is regarding the running for Weather research
and Forecasting Model (WRFV 3.2.1). I get the following error while running
with mpirun. Any help would be highly appreciated.
