# Build options for gfortran compiler (GNU) on Linux AMD64 platform
#
#  Tested with gcc-gfortran v4.1.x as shipped with Fedora Core 6,7,8
#         with gcc-gfortran v4.3.x as shipped with Fedora Core 9,10
#
# OpenMP : Tested on dickens with gcc-gfortran v4.3.2 as shipped with FC 10
#              on baudelaire with gcc-gfortran v4.4.5 as shipped with FC 13
#              on danton     with gcc-gfortran v4.5.1 as shipped with FC 14
#              on acesgrid   with gcc-gfortran v4.6.0 as shipped with FC 15
#
# MPI : Tested on acesgrid (Fedora Core 15), using:
#       module load gcc     (Version 4.6.0)
#   and with mpich1:
#       module load mvapich
#   or  with mpich2:
#       module load mvapich2
#   or  with openmpi:
#       module load openmpi
# and on baudelaire.csail.mit.edu (FC13), using:
#       export MPI_GCC_DIR=/srv/software/gcc/gcc-packages/gcc-4.4.5/mpich2/mpich2-1.3
#       export MPI_INC_DIR=$MPI_GCC_DIR/include
#       export PATH=$MPI_GCC_DIR/bin:$PATH

#-------
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS
#    and generally, needs to increase the thread stack-size:
#   -  sh,bash:
#     > export OMP_NUM_THREADS=2
#     > export GOMP_STACKSIZE=400m
#   - csh,tcsh:
#     > setenv OMP_NUM_THREADS 2
#     > setenv GOMP_STACKSIZE 400m
