1207.0. "looking for IFT sites for DF90AU manual parallel decomposiition" by TLE::WHITLOCK (Stan Whitlock) Fri Feb 28 1997 14:29

DF90 on AU is implementing directives for parallel decomposition.  {If you
didn't understand any of the words in that last sentence, don't bother reading
the rest of this!}  And I mean "DF *90* on Alpha/UNIX *only*".

We are looking for some internal users to pre-field test this stuff staring in
Aplril-1997.  If you are interested, please send mail to

	TLE::WHITLOCK	or	[email protected]

explaining what testing you might be able to do.  Here's some more details:

We are following industry standard practice defined by the old ANSI X3H5
committee and SGI with some Cray spellings too.  For example,

    Parallel Region	CPAR$ PARALLEL		with IF (logical-expr)
						     SHARED (var-list)
						     PRIVATE (var-list)
						     LOCAL (var-list)
			CPAR$ END PARALLEL

    Parallel DO		CPAR$ PARALLEL DO	==	C$DOACROSS

    Parallel Section	CPAR$ PSECTION ... CPAR$ END PSECTION

    Critical Section	CPAR$ CRITICAL SECTION ... CPAR$ END CRITICAL SECTION

    Barrier		CPAR$ BARRIER

    Copy In		C$COPYIN item-list

    Task Common		CPAR$ TASKCOMMON common-block-list

This is not the complete list and certainly not a complete description but
it should give you the idea.
