[mpich-discuss] problem with mpiexec while running parallel execution

[Elie M]

Thanks very much for the help. Actually i could not run mpiexec -info (there was no -info option); however a colleague gave me another (rather more complicated) script to do the parallel run. Now, I get another error which is the following:
"/var/log/slurm/slurmd/job785314/slurm_script:
line 95: cd: /storage/fis718/ananias/GB72scfPH.785314: Input/output error
/home_cluster/fis718/eliemouj/espresso-4.3.2/bin/./pw.x: symbol lookup error:
/home_cluster/fis718/eliemouj/espresso-4.3.2/bin/./pw.x: undefined symbol:
mpi_init_

/home_cluster/fis718/eliemouj/espresso-4.3.2/bin/./pw.x: symbol lookup error:
/home_cluster/fis718/eliemouj/espresso-4.3.2/bin/./pw.x: undefined symbol:
mpi_init_"


I have googled that error but could not understand a lot about what the possible solution could be. I am sorry to bother you with this but i am Linux newbie and these problems are complicated for me at this stage. Can you please help me in this by posting a detailed solution of what can be done, if possible.
Regards
Elie
