Extrinsic procedures have a number of constraints placed on them so
they behave in the same way as `regular' HPF procedures. An EXTRINSIC
must:
- fully terminate before control returns,
- not permanently change the mapping of an object,
- obey any INTENT,
- ensure that non-local replicated variables have a consistent value,
- not permanently modify the number of available processors.
