Not to be petty, but RealityEngine in a Crimson or deskside POWER Series systems can have a maximum of two (2) raster boards for a total of four (4) graphics boards.  The VGX and VGXT graphics subsystems would comprise either 4 or 5 boards each depending upon whether either subsystem had the MultiBuffer option (second raster board).

This sounds like you have a starter indigo with 4.0.1, and the 'wrong'
PROMs.  DMA of certain things (such as the granite background) would
cause the system to crash.  Aprox 300 such systems were shipped, and
all were supposed to have long since been upgraded to a later OS
release, or to have had the PROMs released.  Apparently you got missed.

If my diagnosis is correct, please call the TAC, tell them you have a
starter Indigo with the granite background bug, and get them to ship
you 4.0.5.  It should be free; if not, ask them to escalate  your
call.

Hello all...

I am having continued troubles with lprm from my new Indigo to an older
Tektronix XD88 workstation.  lpr and lpq all work fine, and printing
occurs without a snag.  BUT, when I try an lprm, lprm immediately returns
and nothing happens.

My /etc/printcap entry is simple enough (tes is my remote printer):

and all directories are in place, etc. Nothing interesting appears in SYSLOG.
Any thoughts ??

We here at Ford SciLabs are in a rather interesting dilemma, one in which
perhaps others in the SGI/OPENGl community may find themselves.

We need to start developing our OpenGL application "now", and really do not
relish the thought of writing regular old code for nine months and then
having to rewrite it in OpenGL again.  I was hired to initiate a project in 
Open GL and was disappointed to learn of how long it will take before OpenGL
will be shipped.

Has anyone given any thought to
writing a quick-n-dirty temp version of the OpenGL library, using old
GL calls?  I know it wouldnt work for heavy duty stuff, but a certain 
portion of the lib could perhaps be worked out for less intricate code.

Do you think it could work?  I'd like to hear "your" opinions before I actually
attempt it! Maybe,if there's enough interest, efforts could be coordinated for a quick implementation..

Date: Tue, 18 Aug 1992 04:38:58 GMT

Hello folks,

This may be better answer for another group, but I don't know which one.
Anyhow, I was wondering why xcalc stores numbers with only 5 decimal
places valid.  I was doing the following calculation in rpn mode :

1) I entered and stored the value 154.5157925 in STO 1
3) I cleared the display
4) I recalled RCL 1 (it shows 154.51579)
5) Had to press "enter" even though in normal HP's you don't
3) I entered 154.5129008 and pressed "-"
4) Shows "0.0028892" as result

If the same calculation is done :

1) Enter 154.5157925
2) Enter 154.5129008, and press "-"
3) Shows "0.0028917" as result

I checked the result with an HP-11C and it gives "0.0028917", the same
as the later via xcalc.

Is there any way to get better precision out of xcalc?

BTW, I realize that I probably should use bc, but I would much rather use
a nice graphical calculator instead.

It's my understanding that MIPS specifically did NOT want to use
code optimized specifically for the R4000 in the Specmark suite.
To wit: I believe the code wasn't even compiled -mips2 (which
is clearly supported), much less with -r4000.

I have been lead to believe this is because MIPS wanted to
accurately represent processor performance with code compiled
to run on any MIPS machine, hence the -mips1 compile switch.

I don't believe I've ever seen Specmark numbers for an R4000
with the code compiled -mips2 -r4000, or even just -mips2
(although I would dearly love to).

One would think it prudent marketing for MIPS/SGI to release
both sets of numbers. One for compatibility mode (useful for
software houses, which will compile -mips1), and one for raw
"fast as we can get it" mode, which is the most useful number
for the embedded market and end-users. Not that Spec is terribly
useful as a performance indicator in the embedded market, but
it would make my discussions with management SO much easier.

Subject: Fastest way to transform points???
Date: 23 Aug 92 01:07:36 GMT
Article-I.D.: milton.chuckb.714532056
Organization: University of Washington

I recently attempted to speed up some things that I was doing.
Namely I wanted to decrease a bottleneck's effect.  I found I
was transforming points and multiplying matrices a lot.

I us a standard matrix multiplier for this purpose.  IE unrolled
4x4 matrix multiply.

I attempted to improve performace using something like

 	pushmatrix();
     	loadmatrix(M1);
	multmatrix(M2);
    	getmatrix(M3);
	popmatrix();


This fragment turns  out to be about 1/3 the speed of my 4x4
matrix multiply

100000 mat multiplies   took 2.51 seconds
100000 point transforms took 0.76 seconds
100000 sgmat multiplies took 11.27 seconds
 
The 1.05 second case is uses stack manipulations.  I rewrote the
code to only do the following:

	multmatrix(M2)

This code did the following:

100000 mat multiplies   took 2.51 seconds 
100000 point transforms took 0.76 seconds
100000 sgmat multiplies took 2.45 seconds
  

This leads me to believe that there is no hardware involved in
the stack multmatrix routine.  I suspect that the difference in
performance is because of the matrix inversion that takes place
when a loadmatrix call is made.

These results seem to be somewhat consistant.  IE a point takes
around 1/4th the time of a matrix multiply.  (I did do an sginap
after I opend the window to give the window manager a chance to
open the window etc)

These results are for on a PI 4D25 (the 4D35 gives similar
results only faster) hinv says:
	1 20 MHZ IP6 Processor
	FPU: MIPS R2010A/R3010 VLSI Floating Point Chip

	Graphics board: GR1.2 Bit-plane, Z-buffer, Turbo options
	installed

My question is.  Is there a faster way using some of the "built
in matrix 'stuff'"?  If there is not are there faster ways of
making the transform.  I know I can reduce it to a 4x3 matrix
multiply for a gain of 25%.  Are there other such optimizations?

Actually, just adding choppers to dog  and letting the user choose color
coded teams would be a tremendous boost.  We used to get games of up to
10 people going on a network of 4D/25's.  The only problem was it became
a massive free for all (aka blood-bath) without any team organization or

Here's some more data I compiled.  All of these machines had the prom monitor

Obviously 'setenv bootmode C' hasn't helped my problem.  None of the

I am in the process of setting up quotas for users on IRIX 4.0.2, but
the following error occurs when edquota is invoked:

quotas: Package not installed

The quota has been turned on using chkconfig and the 'quotas' file is
created on the root directory of the filesystem.  Any help
appreciated.

Thank you. Is this in a header file? I couldn't find it and just hacked in the  
declaration from the man page.

You may want to make sure that you add shutdown to your /etc/ftpusers
file!  If you let a person ftp as root there is no reason why he would
not be able to just upload a new /etc/passwd file, or am I missing some
basic piece of security that has already been discussed?

Never trust anyone to have addressed ALL of the security issues.
