Problem with carma_reft.nc file

Hi all,

I'm trying to use CARMA/PMC with WACCM4. (sorry for cross posting here!)
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.
forrtl: error (78): process killed (SIGTERM)

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.

Is there any chance it might be related to different versions of different libraries?
Do you have any suggestions how to resolve this?
Thanks a lot!

CARMA is handled by the CAM-Chem group, so I will be moving this to their forum
