I have the opportunity to use three different Silicon Graphics machines:

    4D/320, 4D/440, 4D/480

Supposedly the 320 has 2 R3000 processors, the 440 has 4 R4000 processors,
and the 480 has 8 processors.  What I am interested in knowing is how fast
are these machines compared to a Sun SPARC 2 with 32 Mb, and is trying to
program parallel codes on them worthwhile.  Are they MIMD or SIMD Parrallel
machines?  If you are going to program on them, what language is best,
ie. C/C++ or Fortran 90.  I really want to get into parallel programing
and my current research project seems to lend itself to it.  Are these good
machines for getting exposed to parallel programing?  Thanks alot for your
time!

Dear comp.parallel, I have received significant responses (positive)
about the pvm_mail@helios.llnl.gov mailing list.

PLEASE SEND REQUESTS to pvm_request@helios.llnl.gov, NOT pvm_mail.
People get upset about the large number of administrative requests
likely to be generated by such mistakes.  Several well-meaning people
have done this already.

I have gotten enough mail to suggest that we set up comp.distributed
immediately.  Dave Forslund and I have discussed this briefly, we will
have some time of rotating moderator between interested, responsible
parties.  For now, I am going to propose the group, and tell you if
/where we need votes to get it approved.

Again, please use the mailing list politely.

In a recent report posted to the net, David Kahaner said that the

What exactly is the processor omega?  Is it similar to the

September 14, 1992 - Meeting notice 


MasPar - Supercomputing With a SIMD Architecture

The high performance computing world is becoming increasingly focused 
on MIMD based machines;  MasPar believes that the "MIMD hysteria" has 
clouded the real problem, delivering application performance. Their VP of 
Technology and Architecture, Tom Blank, will discuss the applications 
which best utilize the MasPar autonomous SIMD architecture. Tom is 
uniquely qualified to do this; it is our understanding that he was the prime 
developer of the architecture. Too, this will be the first public presentation 
of their new I/O system which provides solid state disk, I/O buffering and a 
shared extended memory with transfer rates up to 1GB/sec. As usual, we 
will explore third party opportunities for our members with MasPar. And 
we will want to know if they are targeting industrial and commercial 
customers for their machine.

The meeting will take place at 7:30PM at Sun Microsystems at 901 East San 
Antonio Road in Mountain View, California. This is just off the southbound 
San Antonio exit of 101; northbound travelers also exit at San Antonio and
take the overpass to the other side of 101.

Please be prompt; as usual, we expect a large attendance; don't be left out or 
left standing. There is a $8 fee for non-members and members are admitted 
free.

Distribution: fj

The PARALLEL Processing Connection is an entrepreneurial 
association; we mean to assist our members in spawning very 
successful new businesses involving parallel processing.

Our meetings take place on the second Monday of each month at 7:30 
PM at Sun Microsystems at 901 East San Antonio Road in Mountain 
View, California. This is just off the southbound San Antonio exit of 101; 
northbound travelers also exit at San Antonio and take the overpass to 
the other side of 101. There is an $8 visitor fee for non-members and 
members ($40 per year) are admitted free. Our phone number is (408) 
732-9869 for a recorded message about upcoming meetings.

Since the PPC was formed in late 1989 many people have sampled it,
found it to be very valuable, and even understand what we're up
to. Nonetheless, certain questions persist. Now, in our third
year of operation, perhaps we can and should clarify some of the
issues. For example:

Q.    What is PPC's raison d'etre?
A.    The PARALLEL Processing Connection is an entrepreneurial
organization intent on facilitating the emergence of new
businesses. PPC does not become an active member of any such new
entities, ie: is not itself a profit center.

Q.    The issue of 'why' is perhaps the most perplexing. After
all, a $40 annual membership fee is essentially free and how can
anything be free in 1992? What's the payoff? For whom?
A.    That's actually the easiest question of all. Those of us who
are active members hope to be a part of new companies that get
spun off; the payoff is for all of us -- this is an easy win-win!
Since nothing else exists to facilitate hands-on entrepreneurship,
we decided to put it together ourselves. 

Q.    How can PPC assist its members?
A.    PPC is a large technically credible organization. We have
close to 100 paid members and a large group of less regular
visitors; we mail to approximately 500 engineers and scientists
(primarily in Silicon Valley). Major companies need to maintain
visibility in the community and connection with it; that makes us
an important conduit. PPC's strategy is to trade on that value by
forming alliances with important companies for the benefit of its
members. Thus, as an organization, we have been able to obtain
donated hardware, software, and training and we've put together a
small development lab for hands-on use of members at our Sunnyvale
office. Further, we've been able to negotiate discounts on
seminars and hardware/software purchases by members. Most
important, alliances such as we described give us an inside
opportunity to JOINT VENTURE SITUATIONS.

Q.    As an attendee, what should I do to enhance my
opportunities?
A.    Participate, participate, participate. Many important
industry principals and capital people are in our audience looking
for the 'movers'!

	2)  Do you know other tools of this kind (with a FORTRAN interface)?

	3)  Where is it possible to find docs about Pablo?

	4)  Has anyone out there already used Xab (PVM with possibilities for

have suffered through those bugs in the initial release!   Again,
the library is available via anonymous FTP at:

              36.22.0.120     mojave.stanford.edu

We have received a number of email questions from users who  have
not  yet registered with us.  For a variety of reasons (including
legal ones), we do wish to maintain a complete list of our active
users.  Since  we have shown a certain amount of trust by leaving

your  voluntary co-operation.  Please send us email if you forgot
to let us know that you have a copy, or if  you  forgot  to  tell
your friends to send us e-mail before suggesting them to download
a copy.

The next major release will include socket code that  will  allow
the  library  to  run  on  a  cluster of SGI workstations.  Since
sockets can be a little  dangerous  to  play  with,  we  are  not
planning  to  make  beta release  available through anonymous FTP

Subject: Information needed on load balancing in distributed systems.
Date: 27 Aug 92 12:59:15 GMT
Distribution: fj

I am involved in a project whose goal is to develop a system for
scheduling batch and interactive jobs in a network of UNIX
workstations.  The goal is for users to be able to submit jobs and
have our system decide the best place to run those jobs.  The system
should take into account factors like expected CPU usage of the job
vs. power of the host, the location of the input and output files of
the job vs. the server locations on the network, expected memory usage
of the job vs. the memory and swap size on the host, etc.  We do not
have to deal with process migration - once jobs are assigned to a
host, they stay there.

I would like to know if there are systems out there which already
solve this problem.  Currently I have information about the Network
Queueing System (Sterling Software) and Load Balancer (Freedman Sharp
and Associates).  NQS is public domain software, but unfortunately for
our purposes it is not satisfactory because it only deals with
queueing, not load balancing.  Load Balancer performs most of the
functions we want, but is a commercial product, which brings up other
issues such as licensing, not to mention paying for the thing in the
first place. :-)

I currently have a reasonable set of papers dealing with load
balancing, but would appreciate pointers to recent papers (1991 and
on).

Thanks in advance.

I was very suprised to see this (and resented it).  A commercial posting on
