Subject: Using PC-based CDROMS on My Indigo
Date: 12 Sep 92 12:24:43 GMT
Organization: University of Texas at San Antonio

Now that I have built two "MPC's" (Multi-media PC's) from various components
(i.e. 486 motherboards, ViewSonic 7 screens, SoundBlaster Pro audio cards,
etc) I REALLY appreciate how elegant and fast my Indigos are for multimedia.

However, the CDROM market for MAC/PC machines is SOOOO MUCH BIGGER
than that for SGI (I know, this is an old story). What I want is to
be able to RUN (not just read) these CDROMS's on my Indigo (e.g.
Microsoft Bookshelf, Oxford Dictionary, etc.). Is there any hope that at 
some future date that this might be possible? I know that SGI has licensed 
"QuickTime" from Apple. Does this mean that I might be able to use Macintosh 
CDROMS someday? I know we're talking about more than just reading the
CDROM, but also converting the sound/video information to a SGI-compatible
formats. Will SGI's recent deal with Avid Technologies help in this regard?

Thanks.

I compiled gdb4.6 under 4.0.1 no problem, however though gdb executes,
when I strat an executable with it, the executable heads into never
never land.

Specifically, I set a break point at main then then type run, the
executable and gdb then hang indefinitely.  Has anyone gotten gdb to
work under 4.0.1?

I was advised to use "make SHELL=/bin/sh" and that got through the first
problem.  I HAD used the configure script, but didn't see anything about
unly using sh.

The problem seems to be SGI-specific.  The make choked on the lack of
a definition for ut_host in utmp.h, and I've heard previous comments on
problems with a non-standard utmp.h on SGI's.  I have no idea what the
reality is and I'm not flaming SGI about this, but that seems to be where
the problem lies.

I find that people with SGI systems generally have a better idea of why
stuff won't compile on an SGI than most, and after the basic compilation
problems are resolved is the time to start reporting bugs.
But I may be wrong.

Organization: University of Washington

Hej,

I've got a 4D/20 that I moved from one room to another, and after said  
move the system won't come up on the net.  Worked fine before the move.  

A console message keeps repeating ad infinum:

ec0:  dying and restarting

The transceiver (ST-500) collision light is constantly lit, whether  
connected to the ethernet or not. 

The problem is not the transceiver or xceiver cable; I've swapped both  
out.  Same symptoms.

Does this sound like an ethernet hardware problem, or is there something  
easy I could try before I call in the (expensive) repair guys.

Email is best.

Thanks,

bb

Organization: Martin Marietta

Howdy,

This is probably a FAQ, but...  if I could find one, I would
have looked there first.

I manage a network which includes 4D/35's and Indigo's.  Now I
typically worry about minor things such and filesystems, etc,
but the users have been jumping on me about the screen realestate
differences between the 4D/35's and the Indigo's.

My Question:	Is there a way to configure the .sgisession (or
		.Xdefaults) file to recognize the resolution and
		proportion the display area appropriately/auto-
		matically.  (So that Joe's mailbox and calendar 
		show up in the "right" places!)

My local SGI guru passed on a tidbit of info which had been sent
to him.  It suggested the following modes to the ~/.sgisession file:

	#if WIDTH==1024
	#  define SMALL
	#  define WSHFONT -*-courier-bold-r-normal-*-12-*-75-75-*-*-*-*
	#else
	#  define WSHFONT -*-courier-bold-r-normal-*-*-100-*-*-*-*-*-*
	#endif

	XWsh.Font:  WSHFONT
	emacs.Font: WSHFONT
	etc...

But this only seems to address the font problem.  And when I tried it,
did not really seem to do anything.

If anyone has any ideas, it would be greatly appreciated!

We have found the 3.10 optimizer (-O, -O2) to be less reliable than the
2.20 optimizer.  In particular, watch out for loops where the increment is
done somewhere within the loop.  For example (bug already filed with customer
support),

	result = 0;
	len = strlen(s);
	while (len > 0)
		if (s[--len] == '*')
			result = 1;
	return result;

returns 1 even when the string doesn't have an asterix in it.

Unfortunately, we have inherited 10's of thousands of lines of code, that used
to work, with the above idiom scattered everywhere.  And rather than examine
each line, we now compile it -O1 with the consequential slower performance.

The source code to amesh is included on the "Totally Insane"

tools, libraries and utilities (such as source code for handling
3D geometry, fonts, and images).  The disc was given to those who

The FFT is computed on the R3000 CPU.  From a quick look
at the source, it looks like the FFT is being computed using
floating point arithmetic, off a pre-built table of sine and
cosine values.  However, I'm not an expert on FFT code, so
I could be mistaken.  Perhaps Bruce or one of the audio gurus
can correct me if I'm wrong.

I developed a program to render a landscape on an SGI-INDIGO.
In the first part of my program, I'm drawing the landscape,
using the perspective projection( znear=1.0, zfar=10000.0) and
the viewing transformation lookat.
Some special objects are drawn in feedback mode to get the screen-
coordinates. After some specific algorithms, these objects are
drawn into the landscape with the orthographic projection ortho
(... znear=1.0, zfar=10000.0 ).

Now my proplem is, that the hidden surface algorithm doesn't work
correctly in the second part.
I think, that the scaling of the z-buffer isn't the same in the
two types of projections.

My questions: How does the scaling of z-buffer work?
              Is there a way to convert z-buffer values, get by 
              feedback, into eye-coordinates?
              Is there an error in principle in the described
              method?

Hi ...

We are using a Personal Iris 4D/35, running IRIX 4.0.4, to run a
real time control task at 50 Hz. 

The real time task is created using sproc(), and given a non-degrading
process priority using schedctl(NDPRI, 0, NDPHIMAX). All memory in the
program is locked using plock(PROCLOCK), and stack space is locked as 
well using mpin(). The real time event is generated by a VME bus
interrupt that is caught by our own driver, which then calls the
kernel routine pollwakeup() to wake up the real-time control task
which is waiting inside a select().

We can verify the performance of the task using an oscilloscope.
It runs fairly reliably (with a maximum jitter of 2 or 3 msec.) if I
edit files, run make, or list directories. However, serious delays
of around 200 msec. or so can be caused by things involving the
screen display -- such as moving and exposing windows. Scrolling
inside an xterm window will also cause such a delay (although
scrolling inside a winterm does not).

Our documentation on IRIX real-time talks about guaranteed process
dispatch times of 1 to 2 milliseconds for real time tasks. So ...

1. What really _is_ the worst case process dispatch time?

2. Is there anything we can do to improve ours? (short
   of booting the machine single user :-))

From "IRIS Universe", issue number 20, pg 70:
---------------------------------------------

"Silicon Graphics has announced its support for the Quorum Compatibility
Engine, an enabling technology from Quorum Software Systems, Inc. that
allows software written for Macintosh PCs to run on Silicon Graphic's
family of RISC based workstations and servers.  Support of the package
means that developers of technical and commercial applications can
recompile their packages to run on Silicon Graphics' 3D color
workstations.  Technical users needing powerful UNIX based software can
also move up from the Macintosh, while keeping the productivity,
illustration and entertainment packages they use on their Apple
Products.  The Quorum technology will let users run Mac applications on
RISC based workstations while taking advantage of the Display PostScript
system for screen imaging.  Users who have PostScript printers will be
able to get one-hundred percent screen-to-printer accuracy from their
Macintosh applications.
     Silicon Graphics will support two software products, Latitude and
Equal, both built upon the Quorum Compatibility Engine.  Latitude, a
product for software developers that allows cource code to be compiled
with minimal modification for use on UNIX computers, will be especially
attractive to Macintosh users requiring the CPU performance, 3D
capabilities and color computing functionality of the IRIS Indigo RISC
PC.  Equal, a product designed for users of IRIS and other UNIX systems,
interprets shrink wrapped Macintosh applications without performance
penalties.
     Latitude and Equal are scheduled for release in the first half of
1992.  For more information, contact:

   Does anyone have a practical limit of the number of threads that
 can be running (started via sproc(2)) at the same time on an Indigo?
 Are we talking tens, hundreds, thousands?  

   Please e-mail.


                                   Thanks in advance,

                                      -- jogle
