a third run - fourth run - texturing, no display lists [Re: a second run [Re: [Chromium-dev] perfspu output on a parallel app - finding buried treasure]]

[Wes B. <ewb...@r3...>]

This time, using the twoQuadsTwoCPUs demo (a misnomer, it generates 4 quads, 
each of which is textured with a different image, for a total of 4 textures), it 
would appear there is no texture broadcasting going on.

Again, I'll show the logfiles for only one client and one server of the 2-app 
node, 2 crserver run. The client logfile looks kinda weird:

App PE 0:
	 wahtahh	FRAMESTATS	1	TEXELS	245760	245760
	 wahtahh SPUID 0 CONNECTION ID 0 PORT 7000 TOTAL_BYTES RECEIVED 620
	 wahtahh SPUID 0 CONNECTION ID 0 PORT 7000 TOTAL_BYTES SENT 317204
	 wahtahh SPUID 0 CONNECTION ID 1 PORT 7001 TOTAL_BYTES RECEIVED 620
	 wahtahh SPUID 0 CONNECTION ID 1 PORT 7001 TOTAL_BYTES SENT 317448
	 wahtahh SPUID 0 TOTAL FRAMES 37
	 wahtahh SPUID 0 TOTAL CLEARS 74

That's it. There's no more to it than that. I was expecting to see per-frame 
output for each of the quads (a bunch of glVertex2fv calls in this case, rather 
than glVertex3fv calls).

The 245760 texel bytes is correct - that represents transmission of one texture 
that is 256x256 GL_RGB ubyte, and one that is 128x128 GL_RGB ubyte.

The logfile from App PE 1 shows a total of 393216 texel bytes, which is also 
correct, and represents 2 textures, each of which is 256x256 GL_RGB ubyte 
(196608 bytes per texture).

CRserver 0:
		wahtahh	FRAMESTATS	1	QUADS	2	2
		wahtahh	FRAMESTATS	1	glVertex2fv	8	8
		wahtahh	FRAMESTATS	1	INTERP_QUADS	2	2

Here, all the textures are being transmitted from app PE 0 during frame 1:
		wahtahh	FRAMESTATS	1	TEXELS	245760	245760
		wahtahh	FRAMESTATS	3	QUADS	4	2
		wahtahh	FRAMESTATS	3	glVertex2fv	16	8

		wahtahh	FRAMESTATS	5	QUADS	7	3
		wahtahh	FRAMESTATS	5	glVertex2fv	28	12
		wahtahh	FRAMESTATS	5	INTERP_QUADS	7	3

By the time we get to the third frame, one of the textured quads visible on the 
other crserver window starts to straddle the one on this window, so this 
crserver is provided with the additional texture it needs to draw a textured 
quad that straddles the two display windows.

Here, we need another texture because the 4th quad is starting to straddle the

So, this actually shows expected behavior insofar as on-demand delivery of 
textures goes. It would seem that this behavior is not working when display 
lists are enabled, as Karl suggested.
