I just submitted this proposal on stackexchange:

http://area51.stackexchange.com/proposals/57115/houdini [area51.stackexchange.com]

It would be great if we could get more people behind this - I think this could be one of the best resources the houdini community could wish for.

If you don't know about stackexchange, you can read about it here: http://stackexchange.com/ [stackexchange.com]

Here's how you can help:

* register and follow the proposal, you can sign in with your existing google account
* post example questions, ask real, specific questions that you're actually interested in

Help get this past the ‘definition’ phase… and turn it into a real stackexchange site.

in case anyone is interested, i've been trying this out on the weekend and got really interesting results..

I changed around and compiled the particle demo that comes with the cuda sdk as a library, using the nvcc compiler

here's a video of the particle demo:

then i wrote a sop node that links that library. I get 200.000 interacting particles at 20 frames per second… (32768, the default of the demo, at 125)

but, this is with the sop node running 500 frames in one go, so there's very little overhead, i just read back the final positions after 500 frames.

gonna have to test how slow it is to read back every frame etc.

oh… this is with a >very lowend< 9500 GT! the GTX 275 (150 uk pounds i think) should be over 10 times faster

yes that's as far as i got as well, so we're hitting the same wall ;-)
