#
#  Build options for the intel 11 & 12 fortran compiler
#
#  Tested on baudelaire (FC 13) with intel compiler v.11.1.073 (20100806)

# OpenMP : tested on danton (FC 14) using intel compiler v.11.1.046 (20090630)
#                                              and also  v.12.0.4   (20110427)

#-------
# 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
