mpirun: error while loading shared libraries

[hzh_1211]

Hi,everyone.
I have created the boundary, initial,forcing and grid file from ROMS-AGRIF. I have activated mpi and during compilation no errors are there, and run successful at mangers node. But when I change to the computer nodes, successful compilation jobcomp, then run the model the following error is coming:
mpirun: error while loading shared libraries: libpciaccess.so.0: cannot open shared object file: No such file or directory

This sounds like something to take up with the people who maintain the computer you are using. Ask them for working examples of how to submit MPI programs on the compute nodes. However, a web search on your error brings up:

The error has been fixed by setting LD_LIBRARY_PATH.

You need to know what to set it to on your system.

Thinks to your reply, I have solved this question by insalled mpich3 in computer nodes again.But I found the running speed with mpirun was slower than that without mpirun, why?
