OpenCL Dev Kit now out for Cell

That's great !

 

Cool

EDIT: Damn, the thing needs registration before a download. WTF

What is with all these mega-tech-corps' registration crap?

 

Has anyone actually tried this? Does it have proper SPU support? It would be interesting to see what kind of performance you get compared to hand optimized spu shaders.

I'm currently in the process of finding a screwdriver so I can upgrade my PS3 drive. Can't wait to give this a go.

 

I haven't upgraded my PS3 Linux for quite a while, so I am not sure whether this will run on my PS3 or not.

If this works on PS3, it would be quite interesting, although I'm curious on how they implement the memory hierarchy. My previous experiences with programming the SPE is not very good though. OpenCL should be a much better experience if it's done well.

 

Yeah I'm really interested in giving this a go. To be honest I prefer the SPUs over OpenCL but that's mainly because I have this thing for the PS3 hardware. If OpenCL will evolve to a generic framework that works on cpu/gpu/ppu/spu that'd be pretty awesome.

 

Where can one find OpenCL samples and projects ?

 

If you grab the ATI Stream sdk it includes some nice Open CL examples that should get you started.

 

There's also some at Apple (type open cl in the box to see them only).

There are more than one OpenCL implementations on PS3:

That's reasonable, as SPU are very different from the PPE.

The OpenCL/opencl.h vs CL/cl.h is pretty annoying. Basically all OpenCL program which wants to be portable to Mac has to do this:

Code:

#ifdef __APPLE__
#include <OpenCL/opencl.h>
#else
#include <CL/cl.h>
#endif

It's done this way in cl.h provided by Khronos.

 

For people who want to try out OpenCL on the PS3, you should start here:
http://forums.ps2dev.org/viewtopic.php?t=12567

It contains custom instructions to make IBM's XLC compiler install on the PS3.

There is a typo:
56. local ($cmpFixVer) = "0.1.0-0";

should be:

56. local ($cmpFixVer) = "0.1.1-0";


The rest should work fine.


I'm fixing some stubborn Bluetooth keyboard issues. Should be able to run some OpenCL sample codes from Apple to compare in a few days time. ^_^

 

Im getting this error when i try to install those rpms from the iso on Ubuntu 9.10 ppc
