AMD OpenCL multi-core CPU demo at Siggraph Asia 2008

[RidgeRacerLord]

Like EnigmaSand. But BETTER.

where can u get the powder toy :)

@sonofhendrix AMD have published their OpenCL implementation (ATI Stream SDK), and it supports both their ATI GPUs and CPUs (where non-AMD models are not officially "supported"). nVidia also have an OpenCL implementation for their graphics drivers, but it is wasteful with CPU. CUDA is fairly mature, but OpenCL is far more portable.

@0LoneTech

do i need any other software to run this program with all 4 cores? because my cpu uses only 25% of his capacity.

[0LoneTech]

@niinja2 Why ask me? I haven't a clue what program you're talking about, but the OpenCL implementation I mentioned should be at developer.amd.com/gpu/AMDAPPSD­K/ ... As for the demo in the video, which I don't know where to find, it presumably has some hotkey to change the number of cores used to demonstrate the speedup. If a GPU-accelerated program shows as using one core, it's probably just wasting CPU time polling the GPU (which does the work).

@niinja2

This version of powder toy isn't available.

[niinja2]

@thepantherx12

to bad , do you know any other easy demos that could test the power of multicore cpu or gpu?

[thepantherx12]

@niinja2

Yeah you could try luxrender it's a ray tracing program that uses opencl and I think runs on GPU and multiple cores.

[Pendrokar]

Makes me think of how much this would fit to a Liquid Wars game!!! :O

[shartep]

Where can we download it please? thank you :)

[sonofhendrix]

@shartep Err incase you havent realized this is from AMD meaning you cant download it. Best bet is to get Nvidia and you will have thousonds of free CUDA demos.

[ghbdtn112]

красиво )))

[cyther39]

wer can i download this software??

[sonofhendrix]

Hah, you must be joking. Only CUDA apps can you download and play with. Its why everyone is getting NVIDIA cards.

[aaaaaFuck]

@sonofhendrix

а шо за прога???

[ComradeSlice]

Да.

How to get OpenCL working in a cpu?

What compiler do i use to get OpenCL working in a cpu?

[bri3d]

The toolkits to do it (still) aren't released yet - so no compiler will do it at the moment, as far as I know.

[Cadmium77]

I don't beleive OpenCL works in a CPU...it works in a GPU, a graphics processor on your high end graphics card (like a Nvidia Tesla or an ATI 4870) and it turns it into a multicore CPU...the ATI 4870 X2 will become an 1600 core CPU effectively boosting computing power by up to 30x

[morgs2020]

I think it runs on both after reading the wiki page for opencl

[morgs2020]

Ahh if you click on more info it says it's for cpu's dsp's & gpu's

[CompsciWiz]

It works on CPU and GPU and whatever other processors are laying around that support it.

[bri3d]

check out powder unaligned org - same gameplay but none of the OpenCL stuff (since OpenCL isn't released yet).

[BlackZaion]

is this demo downloadable?

[phixcoco]

i'mmm eagerly waiting for another demo to show OpenCL on GPu...come on, AMD guys!

[lXT95l]

Awesome !

[fireuser3d]

This is is a demo using the CPU only - that is the beauty of OpenCL - it scales to whatever is available - CPU, GPU, DSP, Larabee... This demo using a multi-core CPU really shows off this scaling and that was the goal (and to be the first public example of OpenCL). Now we just need to see software developers work with AMD to take advantage of the OpenCL drivers

[dr4g0n4v3ng3r]

Hi, AMD..

Is the demo using a GPU ou a "CPU" ou both?

Thks!!

[pietrora]

BEAUTIFUL!

[ZanQdo]

I cant wait

[farallongeographics]

Very cool - I am excited to see how this can accelerate the processing of GIS data which is incredibly CPU calculation intensive

I was just browsing through youtube
