New PS3 information concerning CELL and RSX programming

[mckmas8808]

I can't read Japanese and I sure as hell don't under these programming diagrams. Can someone please translate bits and parts of the page and decode the programming talk?

Example screenshots.

What the hell does all of this mean?

And Titanio this next picture is for you in particular because you seem to now about this stuff. It's a particles demo comparing SPEs to P4 chips.

Video clip of Terrain demo. Here


Chameleon Fish demo explained

Here's the video of the developer that made this demo explaning certain aspects of it.

And here's a even more in-depth explain of the chameleon fish demo. Explains the chameleon name. 6 minutes long.

And here's a picture of the overall system utilization while running this fish demo.

The first talk, where most of your chosen slides are from, seems to be simply an introduction to the Cell architecture and lists a bunch of different stuff that programmers should be thinking about using SPUs (or SPEs, whatever...) for.

It's really just saying "hey - SPUs are good for so many different things, you should be using them loads".

You'll note that they list everything for sound including mixing. Maybe that ought to give people a few clues as to where most of the audio workload will be between the RSX and the Cell <ahem>.

The IBM talk seems unrelated to PS3 - the big clue here being the utilisation of all 8 SPUs, which isn't possible on a devkit (unless any other developers know something I don't!)

The fish talk is basically a case study in moving an existing algorithm over to Cell - it could be the sort of thing that would be useful to someone needing a crowd simulation of some kind in a game, otherwise it's just a pretty demo.

This stuff was posted earlier here:

MrWibble - the fish demos were from a presentation on the PSCrowd library, which is or will be in the PS3 kit. I'm guessing there was a demand from developers for such a library, so they could use such techniques in games. I guess it'll work in conjunction with OpenSteer.

I don't know about that - it seems to me that the SDK is not solely composed of things actually requested by developers

Maybe it's more push than pull then
