OMP_DEFAULT_DEVICE -- Set the device used in target regions
***********************************************************

Description:
  Set to choose the device which is used in a ``target`` region, unless the
  value is overridden by ``omp_set_default_device`` or by a ``device``
  clause.  The value shall be the nonnegative device number. If no device with
  the given device number exists, the code is executed on the host.  If unset,
  device number 0 will be used.
