error while loading shared libraries during real.exe

[edougherty]

Hi, I am having trouble running real.exe, as every time I try to run it, it immediately fails with the following error message:

mpiexec_mpt: error while loading shared libraries: libxmpi.so: cannot open shared object file: No such file or directory

I have had this issue before and made things work by using the following modules:
intel/18.0.5
mpt/2.21

However, now this work around doesn't work. For reference, I am using the precompiled WRF4.2.2.

For reference, here is my job submission script for real.exe:

#/bin/bash

### Project name
#PBS -A P54048000

### Job name
#PBS -N real

### Wallclock time
#PBS -l walltime=00:30:00

### Queue
#PBS -q regular

### Merge output and error files
#PBS -j oe                    

### Select 2 nodes with 36 CPUs, for 72 MPI processes 
#PBS -l select=2:ncpus=36:mpiprocs=36  

mpiexec_mpt ./real.exe

I think you may need to add the directory containing the 'libxmpi.so' file to your LD_LIBRARY_PATH environment variable.

Are you working in cheyenne? if so, please try the command below:

module load mpt/2.22

If it doesn't work, I would suggest that you copy the source codes and compile it by yourself.
