[mpich-discuss] MPICH3 Problem

Tue Feb 3 18:25:42 CST 2015

Can all nodes that you are using do ssh each other? And, can you also try to run an MPICH example, cpi, located in <mpich_top_dir>/examples with the same nodes to see if you run into the same error?

So, after installing the PGI fortran on the shared drive, I re-ran and now I am getting communication error –

Correct. libpgmp.so should be from your PGI compiler installation.

Sangmin,

I have installed MPICH on shared drive but PGI fortran is installed on /opt/pgi which node do not have access.  I am assuming that is the issue currently.  I am trying to re-install PGI on the shared drive to see if that will fix the problem.

Just to confirm libpgmp.so is not mpich file correct?

Thank You
Abhishek

Hi Abhishek,

As the error message says, it looks that the node running the application doesn’t have libpgmp.so. Can you confirm whether the node has libpgmp.so and whether LD_LIBRARY_PATH is correctly set on the node in case that it has libpgmp.so?

Best regards,

Sangmin

HI All,

I installed MPICH3 on a master terminal along with PGI Fortran.  Then used MPICH3 and PGI to compile my software.  When I run the program on the master terminal only I do not have any error messages but when I am trying to run them on one of the nodes, I am getting following message error –

/home/Earth/MODELS/camx/src_611/CAMx.v6.11.MPICH3.pgfomp: error while loading shared libraries: libpgmp.so: cannot open shared object file: No such file or directory

Any help is much appreciated.
