I am trying to setup ROMS for a new Linux-cluster and having some issues. Before I jump to the issue I will provide you with some details of the Linux cluster:

uname -a command gives the following output:

Code: Select all

`Linux acm-chem.psc.sc.edu 2.6.18-128.1.14.el5 #1 SMP Wed Jun 17 06:38:05 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux`

openmpi 1.2.8.

NETCDF4 with HDF5

Intel Fortran Compiler (IFORT 11.1):

Now I am working on using coupled ROMS-SWAN system for studying Rip Currents. I am able to successfully compile my case. When executing the compiled code, I use one processor each for ROMS and SWAN. This is the error I get:

*****************************************************************************************************

**My understanding from the error is that there is a tiling bug in radiation_stress.F which is creating this error. The radiation_stress.F file in my case is not same as distributed by rutgers subversion system. It has been modified to include few more processes which Dr. John Warner and I have been working on. Since I am new to coding in ROMS, I wouldn't be surprised to see a tiling error.**

What surprises me though is that, I also have a different cluster the details of which are provided below. The same simulation works with no error in this cluster.

MPICH

NETCDF4 with HDF5.

******************************************************************************************************

I have tried using PGI complier along with OPENMPI 1.2.8, NETCDF4 and HDF5 in the first cluster and I still get the same error. So I am not very sure what is going wrong. It would be very nice if someone could direct me to possible reason for segmentation fault. Feel free to ask me for any information you need.

Thanks
