# 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). |
| 15 |
|
| 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 |
