#  Build options for the intel 9.0 fortran compiler
#  ph: use ifort compiler options -convert big_endian -assume byterecl

#  tested on faulks (FC.6)
#  was also tested on hugo (FC.4, FC.9), eddy (FC.5)

# OpenMP : Tested on hugo, eddy and faulks
#-------
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS
#    and generally, needs to increase the stack-size:
#   -  sh,bash:
#     > export OMP_NUM_THREADS=2
#     > export KMP_STACKSIZE=400m
#   - csh,tcsh:
#     > setenv OMP_NUM_THREADS 2
#     > setenv KMP_STACKSIZE 400m
