CAM5 stand alone with SMPD


I am trying to build the stand alone version of CAM5 on a linux system with CentOS6, intel fortran 12.1.3, netcdf 4.1.3 built with ifort , mpich2 1.4.1p1  - the serial CAM5 builds and runs fine. I am having problems building the mpich2 version. I issue the following command but get errors related to Fortan 90 compatibility. Any help is greatly appreciated. Cheers, Charles Jones.

The error from the test for the fortran compiler is coming from "f95" which is not an intel compiler.  The error messages indicate that f95 does not recognize the compiler options that we use with the intel compiler (ifort).  The test was executed using mpif90, which implies that the mpif90 in your path (i.e., PATH environment variable) is not invoking ifort.  Looking through the previous diagnostic output it appears that f95 is the gfortran compiler and that your mpich2 installation was built using gfortran.  To get a successful build of CAM using MPI you'll need netCDF and MPI libs that are built with the same fortran compiler.  We've done a lot of testing with intel, not so much with gfortran, so the former is the best bet.


Thanks Eaton,

i rebuilt mpich2 with FC=ifort and the CAM5 stand alone builds and runs fine.
