Running 1.9x2.5 resolution using 64 tasks

[parama_mukherjee@stonybrook_edu]

Hi,I am trying to run the model using a resolution = 1.9x2.5. During configuration I specified the number of tasks to be 64.So I understand that in order to run such a configuration I need to use the npr_yz to suit my needs.However, even after trying out all the possible numbers for npr_yz, i.e : npr_yz = 32,2,2,32npr_yz = 16,4,4,16npr_yz  = 8,8,8,8 none of them seem to work and my run stops with the following error, from which I cannot make out much.60 n0002
61 n0003
62 n0002
63 n0003
CAM atmosphere model initialization
Read in cam_inparm namelist from: atm_in
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.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.
--------------------------------------------------------------------------
ENDRUN:read_namelist:: namelist read returns an error condition for cam_inparm
--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 48244 on
node n2 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------Is there some other thing I need to do here that I am missing out.Please help, Thanks.

The values of npr_yz that you propose are all valid.  That's not the error.  The error appears to be reading the cam_inparm namelist group.  This indicates incorrect hand editing of the namelist files.  The correct namelist group for npr_yz depends on the model version, and the best way to set it depends on whether you are using cesm scripts or cam standalone scripts.
