ANNOUNCMENT
Attached, please find the 02/18/86 list of DHRYSTONE benchmark results.
The source code for the drystone benchmark can be found in net.sources.

The latest list includes many new machines/compiler combinations.  Many
of the questionable results have been confirmed or corrected.  I am still
waiting for Intel 386 results; I'm sure many others are, too.

APOLOGY
There was a line missing in my previous postings of the benchmark. This
caused the results to differ from the 'official' definition of what a
DHRYSTONE is by a factor of approximately 15%.  Hence, the results obtained
by using my version 1.0 of DHRYSTONE are not comparable to any other langauge
version of DHRYSTONE. I have corrected this problem in the latest version 1.1.
I have retained the results list for version 1.0, and with this version,
have started a list for 1.1.  I would appreciate receiving new results
for both 1.0 and 1.1 versions, and results for version 1.1 where I already
have version 1.0 results.  Please identify the version used.  Hopefully,
the results list for 1.1 will grow to the size of the 1.0 list, and then
I can remove the 1.0 list altogether.

REQUEST
Personally, I am sick of reading benchmark results in Byte, PC Magazine,
etc. which use simple "for" loops, the "sieve", or Peter Norton's "SysIndex".
While DHRYSTONE isn't perfect, it is a lot more representative of real-world
computer usage than these simplistic measures.  I don't know how to contact
any of the people who write these articles, but I'd love to see them get
the message and source code for DHRYSTONE.  Can anyone help?

CLARIFICATION
There seems to have been a great deal of confusion over what this
benchmark measures, and how to use these results.  Let me try to clarify
this:

	1) DHRYSTONE is a measure of processor+compiler efficiency in
	   executing a 'typical' program.  The 'typical' program was
	   designed by measuring statistics on a great number of
	   'real' programs.  The 'typical' program was then written
	   by Reinhold P. Weicker using these statistics.  The
	   program is balanced according to statement type, as well
	   as data type.

	2) DHRYSTONE does not use floating point.  Typical programs don't.

	3) DHRYSTONE does not do I/O.  Typical programs do, but then
	   we'd have a whole can of worms opened up.

	4) DHRYSTONE does not contain much code that can be optimized
	   by vector processors.  That's why a CRAY doesn't look real
	   fast, they weren't built to do this sort of computing.

	5) DHRYSTONE does not measure OS performance, as it avoids
	   calling the O.S.  The O.S. is indicated in the results only
	   to help in identifying the compiler technology.

If somebody asked me to pick out the best machine for the money, I
wouldn't look at just the results of DHRYSTONE.  I'd probably:

	1) Run DHRYSTONE to get a feel for the compiler+processor
	   speed.
	2) Run any number of benchmarks to check disk I/O bandwidth,
	   using both sequential and random read/writes.
	3) Run a multitasking benchmark to check multi-user response
	   time.  Typically, these benchmarks run several types of
	   programs such as editors, shell scripts, sorts, compiles,
	   and plot the results against the number of simulated users.
	4) If appropriate for the intended use, run WHETSTONE, to determine
	   floating point performance.
	5) If appropriate for intended use, run some programs which do
	   vector and matrix computations.
	6) Figure out what the box will:
		- cost to buy
		- cost to operate and maintain
		- be worth when it is sold
		- be worth if the manufacturer goes out of business
	7) Having done the above, I probably have a hand-full of
	   machines which meet my price/performance requirements.
	   Now, I find out if the applications programs I'd like
	   to use will run on any of these machines.  I also find
	   out how much interest people have in writing new software
	   for the machine, and look carefully at the migration path
	   I will have to take when I reach the limits of the machine.

To summarize, DHRYSTONES by themselves are not anything more than
a way to win free beers when arguing 'Box-A versus Box-B' religion.
They do provide insight into Box-A/Compiler-A versus Box-A/Compiler-B
comparisons.

As usual, all comments and new results should be mailed directly
to me at ..{ihnp4,..others..}!houxm!castor!rer.  I will summarize
and post to the net.  These results are also being sent to Rheinhold
P. Weicker for addition to his list of Pascal and Ada results.

USENET (Users’ Network) was a bulletin board shared among many computer
systems around the world. USENET was a logical network, sitting on top
of several physical networks, among them UUCP, BLICN, BERKNET, X.25, and
the ARPANET. Sites on USENET included many universities, private companies
and research organizations. See USENET Archives.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO vs IBM.
