What is everyone working on?

You guys have seen my work, and I've heard some people talk about some interesting subjects...

So what's everyone working on, how is the SDK working for your applications?

What is everyone working on?

I'm working on my master thesis.

I have almost finished my application that calculate Dense Disparity Map from Color Stereo Images.

My algoritm is simple because I want only to prove quickness of the GPU

My GPU calculate it about 20 - 50 x faster than CPU.

Here is my output image: http://img399.imageshack.us/my.php?image=out000mj5.png

Neural networks now in debugging state and planing to look at another Computer Science thing, which I won't tell now.

Nice zimoch.  Kos, I really think this technology would be great for servers to procedurally generate and control masses of bots, for any purpose really, I'm hoping to get into a lot of that when I have more time to code.

I'm working on shallow-water systems simulation, still in development phase.

What is everyone working on?

I working with a group of mechanical engineers on NASA's Orion project, the crew-launch replacement for the shuttle.  They are doing the vibration analyses for the launch phase of the craft.  In particular they are trying to dramatically speed-up a single run of model code, which must execute 100's of time to get a statistically significant sample size.

Ooooh!  jski I was thinking about how cool it would be to bring the tech to a place like NASA.  Wanna get me a job?

What is everyone working on?

I am a particle physicist working at the Beijing Spectrometer III experiment in (who would have guessed) Beijing. We search for new particles in the decay of other particles and also want to determine the properties (mass, lifetime, angular momentum) of things we found - the technical name of the field is light hadron spectroscopy. We employ a procedure called Partial Wave Analysis (PWA) to extract as much information as possible in a un-binned log likelihood fit to many (hundreds of thousands to millions) of measured decays ("events"). In each iteration of the fit, we recalculate for each event how likely it is to be produced with the current model parameters. We have a working version of a brook+ based framework, which is about 35 times faster than the legacy FORTRAN code, but there is still a lot of room for improvement.

I was working on coding some benchmarks and LBE code; however, Brook+ is not up to par so I stopped using it, I switched back over to CUDA/Cell at the moment.

That's quite interesting nberger... Any kind of leading edge physics/science applications really grab my attention.  And ryta, I'm sorry to hear your lack of success, keep in mind the new version of the SDK will be released sometime around the second week of december as far as we've heard.  Should bring quite a few features that seem like it will bring the SDK closer to a more mature model.

As for me, I'm sort of lamenting the task, but it is time to design a model that will allow me to implement backends for any and all optimized or general GPGPU APIs.  As well as begin to implement an interface for interacting with my new "noise modules" through a GUI.  Once modularized and optimized it will be time for LOD.

There's a lot of interesting things that I've thought of in the style of SIMD.  A friend of mine works for a security company.  Every camera for instance could have a stream of pixels tested and outputed to a stream of results.  There's just such a leap in efficiency, and we're seeing that across the board!
