First OpenCL demo on a GPU

The first public demonstration of OpenCL running on a GPU was done by NVIDIA on December 12, 2008 at Siggraph Asia. This demo of OpenCL on NVIDIA GPU was based on early non-released OpenCL API/driver interface. The nbody simulation shown was a simulation of massive particles under the influence of physical forces. Nbody simulation is known to be computationally intensive. The demo shows how OpenCL can deliver high performance computing using the parallel cores of the CUDA architecture on NVIDIA GPUs. This demo also illustrates the idea that core computational code can be written in OpenCL and will scale to whatever number of cores are available. The demo shown in Siggraph used the 32 parallel cores available on the NVIDIA Quadro FX 570M GPU that it ran on.

I dont understand why ppl are bringing the descussion ATI over Nvidia and vice versa, or talking about gaming cards.

In this situation id say Quadro, tesla give me those kinds of comparisons, you guys are comparing game cards. When it comes down to the applications of cuda its not about gaming or physics, its about taking parallel processing to a new level.

This does have its gaming applications but its scientific ones are great.

That would be great for making space related games. or aps.

@WXIIIR

You make no sense considering it is a reply to my comment.

Perhaps less paranoia and more comprehensive reading skills.

@solobackpacking OpenCL was first developed by Apple and the first manuals and applications of OpenCL were made for Mac, so your argument is complete crap. i probably shouldn't be saying this as i hate Apple and all that Apple stands for but they came up with a really great thing.

@solobackpacking No, Intel is working along with other developers like AMD and in OpenCL development, and doing well at it.

[solobackpacking]

There isn't a single OpenCL demo app or benchmark app for the Mac that can be downloaded and works.

I have a feeling Intel is trying their best to sabotage OpenCL.

@CypFlyer and openCL does that thing better than CUDA..

@poonwoofer Just wait until quantum computing comes into full play.

@troelsblum but most likely at that time a standard api wasn't necessary and now C hippies command (?) At that time they hardly had compilers probably to even think about it as something really needed--they barely thought parallel computing had any future.

@AspirinaSaucer

Actually the Cray-1 super computer worked in a similar fashion. It was created in 1976

Soon enough we're going to be simulating a big bang event, and thus the creation of a simulated universe.
