A couple of years ago, I helped edit a survey of parallel computing

Alliant:	deceased

AMT:		deceased (but resurrected)
Caplin:		???

Parsytec:	still in business
Sequent:	still in business

SSI:		recently deceased
Stardent:	deceased

TMC:		still in business

And this ignores BiiN, ETA, Multiflow, Myrias, and Symult, who were dead by
the time the book came out, and doesn't include KSR or Tera, who hadn't
released products (and in KSR's case, wouldn't even talk to us) when we were
compiling material.

I also find it interesting that IBM cited lack of clear evidence that a working 
machine would emerge that they stopped funding.  A friend that worked at SSI
said they had a machine on the floor and checkout was going great.  Maybe the
rumor from bownes that IBM was in it for the technology was correct.  They were
so close, to  have to hear from investment bankers that the bankers couldn't 
fund them.

This is a good idea, but as I pointed out, you will not get more than
11 or 12 mflops on daxpy if you stick to Blas-1 (unless you have some
kind of special daxpy [ maybe KAI? ] that assumes that vector 1 stays
in cache and vector 2 comes from main memory, or vice versa).

These people must be using the Delta, huh?  I don't know anyone else
that has 500 i860s. Are they calling blas-2
routines?  If so, I'd definitely believe you, as I know people who get
90%+ performance on 80 or so shared memory i860-XRs using similar

Actually, there's a third effect: on machines with multiple functional
units a load or store to/from a register can be done at the same time as
other operations, so that the register can act like a small programmable
cache (complete with prefetching).

We needed telnetd to behave slightly different for a special project on a
Sequent and obtained the 4.3BSD source.  It compiles without problems.

You should be able to get the source from a 386BSD distribution site on the
net (e.g. agate.berkeley.edu).

BTW, the Sequent runs DYNIX(R) V3.0.17.9 and our telnetd.c's sccsid line says:
	@(#)telnetd.c   5.18 (Berkeley) 5/12/86

Hope this helps,

Something similar to m_get_myid(), which returns me the child process

We are running Dynix/ptx 1.3.0 in an academic environment. None of our
Computing courses feature a language as the main feature of the course, but
several of them require that the student learn a specific language (like
Pascal or Fortran in first year). We are using Sequent-supplied compilers
for both of these languages.  Our Computing instructors are finding that they 
are spending too much class and lab time explaining the use of the standard 
debugging tools (like pdbx), and most students (especially in first year) 
find it nearly impossible to work it out on their own. Is anyone aware of 
more intuitive debuggers that would be more suitable? I would also be
interested in hearing of programming environment packages, where a
compiler/editting facility/debugger where rolled into one package.

Any suggestions will be appreciated.

Summary: looking for clues
Keywords: sequent, dynix
Organization: Kuck and Associates, Champaign IL
Distribution: na
Date: Thu, 28 Jan 1993 15:39:23 GMT

I'm looking for reasons other sites used to justify the huge amount of work to
convert their Sequent system from bsd based Dynix 3 operating system to the
svr3 based Dynix/ptx operating system.  Bsd bigots, please, don't waste
anyone's time with bsd vs. system v religious comments.

We currently have both OS's on our S27, because we support our products on
both, but we continue to run Dynix 3 as our production operating system.  The
system is used for documentation (tex, ditroff), software development, and as
our general administrative system (email, news, etc).  We have no third party
purchased applications to worry about.

None of the users have expressed any preference, or objection, to either OS.
The only reasons I see are related to ongoing support, future enhancements, and
operating system features.  Sequent has said they won't be enhancing dynix 3
anymore, so switching to ptx now, may mean quicker access to new features in
the future.

There are two features of ptx I'd really like to have, namely the nfs lock
daemon and bidirectional modems.  There is also one big feature of dynix 3,
NIS, that sequent says they won't support in ptx.  The (lack of) features
discussion doesn't seem concern anyone here but me.  The enormous amount of
work converting the over 400 locally installed programs vs the benefit gained
by the new features is the reason I haven't switched already.

Can you think of any reason or major feature that might make me reconsider
switching (or not) to ptx?

Thanks for your input.

If you're using tcpd from inetd, then getpeername() will *not* work.
The inetd in ptx/TCP passes a TLI endpoint, not a socket so the correct
routine to call is getpeerinaddr().
I have personally had success making "sockety" programs work from inetd
by popping "timod" off the stream and pushing "sockmod". Your mileage
however might vary and this is not an official Sequent recommendation,
purely personal observation from one too lazy to want to change his
sockets-using programs to use TLI instead :-)
You obviously would not want to do this to tcpd 'cos you'd break all the
programs that get called underneath !

You can add on a Q-bus to SCSI adapter. We ran a CMD 220/TM on our 3200 for 
18 months with no problems at all. It is probably cheaper to expand this way

Recently someone posted asking about software archives for the Rainbow. 
Unfortunately I have lost the reference, but as far as I know there are none
available online until Warner manages to rebuild his lost collection. In the
meantime I thought that I might as well make available the various bits and
pieces which I have collected over the years. This is all public domain stuff.
Unfortunately it is not catalogued properly so I can't tell you what it all is.
None-the-less someone might be able to use parts of it?? (Perhaps it will help
Warner to rebuild?) Maybe someone has something else which should be added?

The collection is accessible through anonymous FTP on luvs1.latrobe.edu.au
(This system is only a MicroVAX 2000 so don't be too hard on it!) Most of the
stuff is in ZIP or ARC format. Some of the files are uuencoded (UUE). My kids
