6  #  Tested with gcc-gfortran v4.0.x as shipped with Fedora Core 4.  #  Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8
7  #  It fixes the ' \' versus ' &' terminator problem but some  #         with gcc-gfortran v4.3.x as shipped with Fedora Core 9,10
 #  namelist problems remain.  The biggest seems to be the inability  
 #  of current gfortran versions to support namelist syntax such as:  
 #  
 #     fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',  
 #  
 #  which results in run-time errors.

9    # OpenMP : Tested on dickens with gcc-gfortran v4.3.2 as shipped with FC 10
10    #          and on baudelaire with gcc-gfortran v4.4.5 as shipped with FC 13
11    #          also on danton    with gcc-gfortran v4.5.1 as shipped with FC 14
12    #-------
13    # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
14    #    and generally, needs to increase the thread stack-size:
15    #   -  sh,bash:
16    #     > export OMP_NUM_THREADS=2
17    #     > export GOMP_STACKSIZE=400m
18    #   - csh,tcsh:
19    #     > setenv OMP_NUM_THREADS 2
20    #     > setenv GOMP_STACKSIZE 400m
