GEOS-DAS Quick Start Failures on Discover

I'm unable to run the GCM portion of the GEOS-DAS on Discover.  I'm using the GEOSdas-2_1_4 tag.


I'm generally following the Quick Start instructions for a MERRA run, but with the following customizations:


AGCM Resolution:  b72

FVINPUT:  /discover/nobackup/projects/gmao/share/dkokron/fvInput  (the default directory doesn't have any input data).

Real time BCS:  /discover/nobackup/projects/gmao/share/dkokron/fvInput/g5gcm/bcs/SST

g5chem:  /discover/nobackup/projects/gmao/share/dkokron/fvInput/g5chem

FVICS:  /archive/merra/dao_ops/production/GEOSdas-2_1_4/d5_merra_jan98


I've tried the following start/end dates:


Start Date:  19980215

Start Time:  210000

End Date:  19980216

End Time:  210000


Start Date:  20000929

Start Time:  210000

End Date:  20001006

End Time:  090000


(The Quick Start start time of 19980205 210000 doesn't have any restart files available).


In both cases the DAS part of the system "works".  But the GCM experiences an MPI error that causes it to hang.  The error message is:


--- mpimon --- Aborting run after process-8 terminated abnormally Childprocess 1

781 got signal SIGIOT( 6):  IOT instruction ---


Note that I'm using ScaliMPI, and the batch script includes the line #PBS -l select=9:ncpus=4:scali=true
