Problem with carma_reft.nc file

[deepashree_dutta@student_unsw_edu_au]

Hi all,

I'm trying to use CARMA/PMC with WACCM4.
I created a case using F1850W compset and enabled CARMA/PMC using:
./xmlchange -file env_build.xml -id CAM_CONFIG_OPTS -val '-phys cam4 -chem waccm_mozart -carma pmc'
(following: http://lasp.colorado.edu/media/meet...rkshop/Papers/Session4/BardeenCAWSES2012.pdf; I couldn't find documentation with more details)
The case builds successfully. But when I submit it, I get this error in cesm.log file:

"MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1001.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

I checked the atm.log file as well. It seems the model fails when it executes carma_intr() and tries to create the carma_reft.nc file (reference T for CARMA). I get “NetCDF: Unknown file format” error when I tried to open carma_reft.nc.
Deleting the carma_reft.nc file and resubmitting the case does not work.

I do not understand what is causing this issue.
Do you have any suggestions how to resolve this?
Thanks a lot!
