# Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8 |
| 8 |
# with gcc-gfortran v4.3.x as shipped with Fedora Core 9,10 |
| 9 |
# It fixes the ' \' versus ' &' terminator ; |
| 10 |
# with older versions (v4.0): namelist problems with syntax such as: |
| 11 |
# fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ', |
| 12 |
# which results in run-time errors.) |

# OpenMP : Tested on dickens with gcc-gfortran v4.3.2 as shipped with FC 10 |
| 15 |
#------- |
| 16 |
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS |
| 17 |
# and generally, needs to increase the thread stack-size: |
| 18 |
# - sh,bash: |
| 19 |
# > export OMP_NUM_THREADS=2 |
| 20 |
# > export GOMP_STACKSIZE=400m |
| 21 |
# - csh,tcsh: |
| 22 |
# > setenv OMP_NUM_THREADS 2 |
| 23 |
# > setenv GOMP_STACKSIZE 400m |
