There is a good chance that the FORTRAN runtime is issuing a system call

strace POP, you can probably find out which system call fails.
One option might be to use MPI-IO from Fortran. Doesn't POP support
parallel-netcdf? that too has fortran bindings.

Hi all,
Recently, I am trying to run POP (Parallel Ocean Program, written with
fortran) with Orangefs. And found that there is always an I/O error
reporting parameter is not correct from POP if I configure it to output
file to Orangefs. But POP works fine if configure
its output to NFS. I also run IOR (written with C) with orangefs, and
everything works fine too. Is there anybody has experience of running
fortran program on orangefs ? How Can I figure out what's the problem?
I tested both kernel module client interface and fuse interface, with
orangefs-2.9.0 version.
Thanks
