#  with multiple CPU's or that support hyperthreading.  Performance will
#  be improved in certain Parasolid operations, such as Mass Properties,
#  Booleans and silhouette generation.  This option is only supported on
#  HP, SUN and Windows NT.

#     Set to 1 to enable SMP
#     Unset will take the Parasolid default
#  UGII_SMP_ENABLE = 1
