seg fault in release-v2.0 #144

Closed mark-petersen closed 10 years ago

mark-petersen commented 10 years ago

I am getting a seg fault with the current version of release-v2.0 on a standard 120km global run. Develop, with the same IC and namelist, runs fine.

It must be a change in the last few commits.

What compiler/mpi/library versions are you using for this?

mark-petersen commented 10 years ago

module purge module load intel openmpi module use --append /usr/projects/climate/SHARED_CLIMATE/modulefiles/all module load netcdf/3.6.3 module load parallel-netcdf/1.3.1 module load pio/1.7.2

I am trying some other combinations now to see if the problem is due to the choice of libraries.

It was my choice of libraries. When I go back to my previous method of compiling, it works fine. That was: source /usr/projects/climate/SHARED_CLIMATE/scripts/mustang_intel_openmpi.csh
