Just curios, how many here use CUDA / OpenCL on a regular basis ? I usually see GPU related posts come to the top around midnight or in the early hours of the day (off-peak hours to be precise). Makes me think that there are enough people working on GPUs out there, just not enough to stand out from the web-dev or other related news that usually get voted up..

I don't but one of my colleague's job is to port existing data analysis algorithms to GPUs. It seems other research centers like ours also have personnel dedicated to this task. Even if I'm more of a python guy right now, I'm still very interested in this stuff and often upvote stories. And I'd be interested in seeing who's using GPUs for science!

  Since you said Python and are interested in GPUs (but not fully immersed in it yet), I want to show you this which can get you started (and also a shameless plug for the product I am the lead developer for) http://www.accelereyes.com/arrayfire/python/ http://www.accelereyes.com/arrayfire/python/ Its a freemium model, should cost you next to nothing to try (as long as you have a gpu).

    I stumbled upon it a while ago. The whole package looked very nice but it seems to be closed source. Being proprietary is fine but some people here tend to dig into libraries to see what they are doing. I don't know if you plan on offering some kind of source access. Also I see that the free edition tries to connect to an outside server to a high port, and that would work here. Our network is not really friendly: I cannot even check out a git repo with the git protocol. I can see the appeal of your product though. Some of my colleagues are trying to use PyCUDA but have to learn C in the process.

I work quite a bit with OpenCL. Here is a micropolygon rasterizer I wrote in OpenCL: https://github.com/ginkgo/micropolis https://github.com/ginkgo/micropolis http://www.youtube.com/watch?v=09ozb1ttgmA http://www.youtube.com/watch?v=09ozb1ttgmA Its performance is competitive with the OpenGL hardware rasterizer, because rasterizing small polygons tends to get very inefficient in current hardware.
