7 # Tested with gcc-gfortran v4.1.1 on FC5, FC6, FC8, using flags
8 # formally for gcc-gfortran 4.3*
9 # + with gcc-gfortran v4.3.0 on FC9
10 # It fixes the ' \' versus ' &' terminator problem ;
11 # some namelist problems remain with old version (The biggest seems
12 # to be the inability to support namelist syntax such as:
13 # fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',
14 # which results in run-time errors).

16 #-------
17 # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
18 # and generally, needs to increase the thread stack-size:
19 # - sh,bash:
20 # > export OMP_NUM_THREADS=2
21 # > export GOMP_STACKSIZE=400m
22 # - csh,tcsh:
23 # > setenv OMP_NUM_THREADS 2
24 # > setenv GOMP_STACKSIZE 400m
