# 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

# MPI : Tested on acesgrid (Fedora Core 15), using:
