Subject: GLX slow rendering problem
Keywords: GL, GLX, shaded rendering
Date: 1 Sep 92 14:54:08 GMT

Organization: Radiation Oncology, NCMH/UNC, Chapel Hill, NC

under GLX. I am guessing that the problem is that some state is turned
on/off and causing the slow down. Unfortunately I am adding additions
to some old X software and do not know exactly which states may be in
effect. Thus my question:

Would someone please tell me what "things" might slow down rendering
under GLX?

To be specific, I am comparing a GLX program I wrote to render ~84000
triangles to some GLX code in a MUCH LARGER program. In my code I am
able to render the triangles in ~ .5 secs (no meshes, the old code
doesn't use meshes). In the old code, this section of code:

for(i = 0; i < num_triangles;i++){
	bgnpolygon();
	n3f(fake_vector);
	v3f(fake_vector);
	n3f(fake_vector);
	v3f(fake_vector);
	n3f(fake_vector);
	v3f(fake_vector);
	endpolygon();
}

takes ~1.6 secs ... more than three times as slow. The fake_vector was
used to make sure that valid values were passed to n3f and v3f. Taking
out the v3f call and leaving only the n3f (just trying to figure out
where the problem is) cuts the rendering time to ~.4 secs in the old
code which leads me to strongly suspect that there is some global
variable set which is interfering with rendering. 

The program I am modifying is quite complex, using, stenciling,
texture mapping, multiple windows under X etc. Things I have been
trying include texturing (turned off), subpixel(TRUE). I would like to
be able to guarantee "a clean environment", render dummy triangles
using n3f and v3f in less than .6 secs, and work back from there. But
right now I can't get anything to render quickly. 

Much thanks to anyone who can give me a clue as to what may be going
wrong. It may be some stupid mistake in my code, but I haven't found
it yet. Thanks again for any help.

Subject: IRIS Crimson upgrade: performance?
Date: 26 Aug 92 21:25:24 GMT
Organization: Southwest Research Institute


We are currently using a IRIS power series, 210/vgx machine, with
(info from 'hinv'):

  1 25 MHZ IP9 Processor                                       
  FPU: MIPS R2010A/R3010 VLSI Floating Point Chip Revision: 2.0
  CPU: MIPS R2000A/R3000 Processor Chip Revision: 2.0

I am writing a purchase justification to upgrade this environment
to an IRIS Crimson, R4000, 50mhz CPU/FPU environment.
                                                                    
To items: (a) any words of wisdom in this upgrade process, and      
          (b) does anyone have any performance results for software 
              execution times both before, and after their upgrade. 
                                                                    
We do hydrologic modeling here, and my people are mostly interested in
F77 and C code performance for fluid transport and pollution plume  
modeling in saturated and unsaturated geologic formations (number
crunching).   Any thoughts, concerns, comments or considerations 
about this upgrade, and it's potential number crunch speed 
improvement would be appreciated.  I am especially interested in
hearing from those who have actually performed the upgrade, and 
have before and after runtime values.    -- Thanks --

  Yes. There is a PD software that provides a gateway between LPD and NOVELL queues.
I think it is called Charon. If I am recalling correctly it also provides SMTP
gateway to NOVELL users. You should be able to get that from risc.ua.edu. Notice that
you should have a dedicated PC that will be running the software.

Nope. 

Since the VideoLab product is *real* popular, and lot's of
users ask this, I thought I would post Our Reasons For No Composite
And S-Video on VideoLab

1. Way back in 1990, we thought that;
	A) The Soviet Union would be around awhile
	B) VideoLab would be a two-board set
   
   Sheesh, were we wrong.

   It turns out that (for a lot of reasons) the second board which
   was to have had the digital encoder/decoder, VLAN transmitter and
   some other goodies was going to be *much* later than the board
   that became the VideoLab we now know and love.

2. Not only was the second board going to trail the first by a number
   of months, but it would have to be priced at around $10K. Now, this
   is not all that bad of a deal considering users would get both 525
   and 625 D2 as well as NTSC, PAL and both versions of S-Video at
   dead-on broadcast quality, but we had to think "Gee, would our non-
   broadcast/pro users want to pay $10K if all they need is composite
   out and maybe VLAN?" With encoders going from < $1K for a VIDI/O
   Box to maybe $3-4K for some mid-range units, and a V-LAN T going
   for about $1K, we thought it would be better to let users spend
   their own $10K on a Faroudja encoder if the need great encoding and
   $1K on a VIDI/O box if they just need to make VHS tapes.

3. The break-out box was designed *before* this was decided, and therefore
   retains the jacks for "Future Expansion".

Also,

4. Most animation/video pro users record in component anyway, and even
   the networks would usually work in component until the last possible
   step in the chain.

And,

5. VideoLab and a low-cost encoder is still cheaper than the VideoCreator
   and most stand-alone scan converters, plus it has input, digital video,
   transcoding, etc., etc., etc.


Any and all comments are invited, as always.

archive program later).  I'd really not want to count on this working.

There is also an example of a passwd checker written in Perl.  It's

Subject: Ethernet adapters on io3 boards stopping.

We have a 4/480 with a dual io3/ setup. For the fifth time this year,
the ethernet interface has suddenly stopped working. Doing a netstat
shows a couple of packets a second only. We have put another system on the
network interface and we see traffic. Has anyone seen similar behavior?
and or have a fix other than changing the io/3 board out every time.

This causes a real problem since netls uses the io/3 board to determine
the system identity, and when you change it you have to get new keys for
everything. This is most critical since we are using networker, and
it is backing up many of our systems and the 1-2 day turnaround to get
the license key leaves a window of vulnerablity.


IN any case, the main question is has anyone seen the io/3 stop working
as suggested above.
