Run HYSPLIT ensemble using multiple processors on linux

[zeinabsalah]

Hi,
I try to run the ensemble concentration through multiple-processor option using hysplit.v5.2.0_RHEL8.5 and hysplit.v5.2.3_RHEL8.6_public on linux, but both of them give me the error:

Running model hycm_ens with 2 processors!
../exec/hycm_ens: error while loading shared libraries: libmpifort.so.12: cannot open shared object file: No such file or directory
../exec/hycm_ens: error while loading shared libraries: libmpifort.so.12: cannot open shared object file: No such file or directory
--------------------------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------

I'm using openmpi version 4.1.0, and even with mpich, the same error happen.
the Makefile.in is attached.
Thank you in advance.

libmpifort.so.12 is a dynamic library provided by the MPICH package. Running the "yum whatprovides libmpifort.so.12" command on our Linux server shows that the library is included in the mpich-3.2-3.2-2.el7.i686 package. Please check with your IT department if the package can be installed on your Linux computer.

Thank you.
It is solved after making "yum install mpich"
