6  #  Tested with gcc-gfortran v4.0.x as shipped with Fedora Core 4.  # Build options for gfortran compiler (GNU) on Linux AMD64 platform
 #  It fixes the ' \' versus ' &' terminator problem but some  
 #  namelist problems remain.  The biggest seems to be the inability  
 #  of current gfortran versions to support namelist syntax such as:  
7  #  #
8  #     fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',  #  Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8
9    #         with gcc-gfortran v4.3.x as shipped with Fedora Core 9,10
10  #  #
11  #  which results in run-time errors.  # OpenMP : Tested on dickens with gcc-gfortran v4.3.2 as shipped with FC 10
12    #              on baudelaire with gcc-gfortran v4.4.5 as shipped with FC 13
13    #              on danton     with gcc-gfortran v4.5.1 as shipped with FC 14

16    # MPI : Tested on acesgrid (Fedora Core 15), using:
17    #       module load gcc     (Version 4.6.0)
18    #   and with mpich1:
19    #       module load mvapich
20    #   or  with mpich2:
21    #       module load mvapich2
22    #   or  with openmpi:
23    #       module load openmpi
24    # and on baudelaire.csail.mit.edu (FC13), using:
25    #       export MPI_GCC_DIR=/srv/software/gcc/gcc-packages/gcc-4.4.5/mpich2/mpich2-1.3
26    #       export MPI_INC_DIR=$MPI_GCC_DIR/include

30    # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
31    #    and generally, needs to increase the thread stack-size:
