With the MPT MPI library (which is the default MPI library on NCAR's cheyenne machine), it is important to set the environment variable ``MPI_TYPE_DEPTH`` to 16 when running CTSM (this setting is required by the Parallel IO library). Typically you should set this variable in your job submission script, using either:
|
|
|
|
.. code-block:: Bash
|
|
|
|
export MPI_TYPE_DEPTH=16
|
|
|
|
or:
|
|
|
|
.. code-block:: Tcsh
|
|
|
|
setenv MPI_TYPE_DEPTH 16
|
|
|
|
prior to running the model.
