Running CUAS-MPI with reading netcdf file. #1
Description
Hi developers,
I am In-Woo Park and I am trying to simulate subglacial hydrology model using CUAS-MPI. I have manually compiled all required packages as follows:
- netcdf-c (4.9.3)
- PETSC (3.19.3)
- OpenMPI (=4.1.4)
- gcc (>=9.4, gcc >= 9.0 supports stdc++-17)
Running following script encounters the following error.
I suspect the issue may be related to missing configuration options when compiling netCDF-C. Do you have any suggestions for resolving this issue?
Interestingly, when I set NN=1, the error does not occur.
- Command
NN=2
exact=$CUASMPI_DIR/test/cuascore/integration/test-exactSteadySolution
mpirun -n $NN $exact 1000.0 101 101 31 86400 out0.nc- Error message

Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.

mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[561,1],1]
Exit code: 1
