[MITgcm-support] model hangs on opteron cluster

[Samar Khatiwala]

Hi

I'm having problems running on an opteron cluster with pgf90/gcc/ 
mpich2 (see optfile below). The code compiles
without error, but the executable hangs. After I kill the job, it  
writes this to stderr:

PGFIO/stdio: No such file or directory
PGFIO-F-/OPEN/unit=11/error code returned by host stdio - 2.
In source file eeset_parms.f, at line number 1372
PGFIO/stdio: No such file or directory
PGFIO-F-/OPEN/unit=11/error code returned by host stdio - 2.
In source file eeset_parms.f, at line number 1372
PGFIO/stdio: No such file or directory

PGFIO-F-/OPEN/unit=11/error code returned by host stdio - 2.

Terminated

In my version of the code, the above line (1372) corresponds to (in  
eeset_params.F)

       OPEN(UNIT=scrUnit1,STATUS='SCRATCH')

Any ideas what might be wrong?

Thanks, Samar
