Dear All,

I am running an application with mpirun but it gives following error, it is not picking up hostlist, there are other applications which run well with hostlist but it just gives following error with 


[pmdtest@pmd02 d00_dayfiles]$ tail -f *_hrm
mpirun -np  /home/MET/hrm/bin/hrm
--------------------------------------------------------------------------
Could not execute the executable "/home/MET/hrm/bin/hostlist": Exec format error

This could mean that your PATH or executable name is wrong, or that you do not
have the necessary permissions.  Please ensure that the executable is able to be
found and executed.

Following the permission of the hostlist directory. Please help me to remove this error.
