Organization: Netcom - Online Communication Services  (408 241-9760 guest)

October 15, 1992 - Dr. Gordon Bell - Where have all the Massively 
Parallel Processing Companies Gone? Who's Next? andWhy?

This month the PARALLEL Processing Connection is honored to welcome 
Dr. Gordon Bell to its platform. Gordon is best known as the chief architect 
of the world famous VAX computer.

Though all of us 'know' that sequential computing ala Von Neuman is 
passe', it does seem to be the MPP companies whose destiny is in question! 
We've asked Gordon Bell to examine the issue of why that is so and 
perhaps even conjecture on the future of the present cadre of companies. Is 
more and bigger ala megaflops to gigaflops and terraflops truly better for 
anyone and anything other than Grand Challenge problems? Doesn't cost-
effectiveness American style mean the economy of scale that would derive 
from thousands of commodity processors operating concurrently? Doesn't 
it also mean a large community of developers writing software for MPP 
machines? And how can commercial users and developers hope to access 
the field as long as the prices of machines and development systems remain 
in the stratosphere? These are some of the vexing questions we've asked 
Gordon Bell to address and we certainly expect a very rewarding evening.

The meeting will take place at 7:30PM in Bldg 5 of the Mountain View 
campus of Silicon Graphics. Exit 101 at Shoreline Blvd, north .7 of a mile 
to Amphitheater Drive, right turn there into the complex. Please note that 
this is a one time only change in date and place of our meeting.

Please be prompt; we expect a capacity attendance; don't be left out or left 
standing. There is an $11 fee for non-members and members will be 
admitted free.

Say what are you guys trying to do, drive people to read HPCwire?
This isn't alt.fan.enm (don't even think about it).  What does this
have to do with supers?  You guys and topics all scared off for fear
of being quoted in the NY Times?  Far more interesting and super related
will be the 40th Ann. party at LLNL on the 16th.  See some of you there.

Actually, he's a fictional person.  NASA has developed a very complex AI 
program to monitor Usenet and repond to it.

The code name for the project was "Green Mirror", and this has evolved to
"Eugene Miya".

Jeez, what's happening to this group. First high school kids, now John Galt.
(Ask Ian if he knows who John Galt is. For that matter, ask Ian's mom if she
knows who John Galt is. I must be getting old, or something.)

Anyway, I believe that Dagny Taggart [sic] and J.G. had one child, who escaped
to the outside world and tried to improve it, using the name of Milton
Friedman.

To go back one step in this thread, I don't know Mary Shafer, but I remember
her as someone who posts to a large variety of newsgroups yet her postings
are always both intelligent and intelligible. Which is more than can be said
for either Eugene or myself.

Hi - PTX 1.1.1 here...

We send and receive mail from our PTX systems to our Internet gateway
system via SMTP.  recently, our gateway system was down, and mail destined
for it (or beyond) was being bounced back after ten minutes, instead of
staying in the queue for days and days.  

What's wrong here?  What do I need to change?  Here's a couple of fragments
from our sendmail.cf file.  I thought that the OT option described how long
it would be before a mail message would bounce.  Also, I can't find
anything in the "F=" options that would make mail messages bounce almost
immediately.

sendmail.cf options fragment:

# wait up to ten minutes for alias file rebuild
Oa10
# substitution for space (blank) characters
OB.

Reply-To: Paul-Pomes@uiuc.edu

Date: Mon, 28 Sep 1992 22:41:37 GMT

Does anyone have a porting guide for programs meant to be invoked by inetd?

I've already learned that the ptx inetd doesn't provide the client program
with the actual socket.  This breaks programs that count on using the
getpeername() call to learn about the remote end.  No problem, just use
the getpeerinaddr() call (*sigh*).  I've also noted the lack of seteuid().
Can setuid() replace it if the system supports _POSIX_SAVED_IDS?

My whole ambition is to get the wuarchive ftpd installed on our ptx
based Sequent.  The more I use ptx, the better AIX looks.  Neither
reminds me much of UNIX.

Subject: Help with understanding of shared memory read/write on Sequent
Organization: The University of Alabama
Date: Tue, 29 Sep 1992 19:32:03 GMT

I am wondering how Multiple-Reader-Single-Writer problem is
handled on the Sequent Symmetry depending on the data item size..

Let me explain the problem.
There are several processes reading data from a shared memory location.
Only one process writes data, item by item. There is no explicit
protection of the critical section. Assuming that the data item is  represented
by a floating point number, is it possible that readers may read corrupted
at bit or byte level data? What is the atomicity of read/write operations ?
Is it determined by the shared memory bus width (64bits) ?

Is there any Sequent publication which explains implementation of
shared memory read/write with respect to this issue?

Thanks for any help,

Subject: filesystems and "free space"
Date: 2 Oct 92 21:39:12 GMT
Organization: ism:c:m/xo

Have the following hardware and OS:
	Balance B8 with Dynix 3.1.2

I've looked over the man pages for tunefs and newfs, and scanned
through the document about the BSD Fast File system in Vol. II of the
manuals, but I'm not real clear on what exactly is going on with this
free space being reserved.  According to the article about the FFS it
says something to the effect that having 10% free space makes things
work better and faster--how and why is this?  What happens when you
cut this down to about 5% or 2% or nothing at all? 

I've also noticed that when using newfs if I specify a value less than
10 to its -m option I get a warning message about "space optimazation"
is being used because less than 10% free.  What exactly does this mean?
What are the ramifications of initially creating a filesystem with
less than 10% free and this "space optimzation" in effect and then
later bumping it up to 10 or better via tunefs?  Does this in itself
cause the filesystem to stop using "space optimzation" and start using
whatever is more effecient?

Note, I get the general idea that having 10% makes things better, and
is the way one should normally create their filesystems, I
just want to understand why and what the situations are that arise
when it is less than 10% and for that matter more than 10%.

Thanks.

I checked the man page for csh(1) and saw "limit" supported, but I

Can anyone out there point me toward some info?

The most likely guess is that you have a version of sendmail which does
not read MX records.  Instead it is perhaps using gethostbyname() in
a version doing nameserver lookups.  But if the code in sendmail is
not DNS aware, it will not be able to distinguish between a temporary
name lookup failure (due to your gateway problem) and a permanent
failure due to a non-existent host.

Most likely your only good solution is to get a better version of sendmail.

Quick snip: Motorola documentations states that 10% free may be excessive
in very large file systems.  It made sense to me.  My thought :  the
ability to locate the next "logical" block within a reasonable "physical"
location is "more greatly" influenced by available individual blocks than by
the total surface area.  I.e.  I can probably find a reasonable place for the
next block based on having 5% (99896 blocks) instead of 10% (199793) on my
preformatted 1gig disk.

responses encouraged.


The "space optimization" message interests me.  I have slightly smaller disks
on my S27 (792MB) and have always used std 10%.

Disclaimer: I think I understand the fast file system.  :-)

inetd retruns a TLI endpoint. The top of the stream has "timod" pushed,
so the hackers guide to porting code meant to run under inetd is:
ioctl(s, I_POP, "timod");
ioctl(s, I_PUSH, "sockmod");
at which point you have a socket, and all your usual code should work.
Warning: this works for me under TCP 2.1 and 2.2.1, but I cannot guarantee
that it will always do so. If you just want a TLI endpoint that you
can read and write on, you just pop "timod", and push "tirdwr" instead.
Hope this makes things easier for you.

>I've also noted the lack of seteuid().

Hmmm, not sure. You can always do some ugly footwork with fork().

Hi - Sequent PTX 1.1.1, sendmail v1.35 here...

Our systems sometimes encounter errors while trying to send mail.  The
two errors we sometimes see are:

...and...

trying to create lock file '/usr/mail/userid.lock'

554 userid... unknown mailer error 15

we get both of these errors occasionally.  in all cases, the userids we're

these errors occur.

What's wrong?  Thanks so much...

You might try:

@book {OSTERHAUG
       , author = "A. Osterhaug"  
       , title = "Guide to Parallel Programming on Sequent Computer Systems" 
       , publisher = "Prentice-Hall"

}

To prevent concurrent modification to shared data, you could implement your own
lock, or use one of the Sequent's own (eg. m_lock()).
