#  These are the build options used with the Intel 9.x compiler for
#  testing on Beagle.
#
#  Please note that the appropriate module commands:
#
#    module add intel/9.1.051
#    module add mpich-mx/1.2.7..1/intel/9.1.051
#
#  will add /home/ibm/util/mpich-mx-1.2.7..1/icc/9.1.051/lib,
#  /opt/intel/cce/9.1.051/lib and /opt/intel/fce/9.1.051/lib
#  to LD_LIBRARY_PATH which is needed by any executables generated
#  with this optfile.
#  The SGE -V option for exporting environment variables may also be
#  helpful if you encounter missing-library problems.  Or,
#  alternatively, one may choose to link with one of the intel
#  "-static" or "-i-static" flags.
