OpenCL Info

Recommended Posts

hi all :angel:

 

just wrote a lil tool that prints out various opencl infos/features of your supported opencl devices.

see it as a way of checking if your gpu was correctly detected as opencl-capable.

 

obviously this requires snow leopard :(

 

binary and source are included in the attachment.

 

update 2011/02/25 (still version 0.2):

* still working in 10.7 (added output below)

* nvidia h/w seems to be restricted to opencl 1.0, cpu works with opencl 1.1

 

update 2010/06/16 (still version 0.2):

* the usual: version 0.2 still works fine with 10.6.4 and no apparent changes

 

update 2010/03/29 (still version 0.2):

* note: version 0.2 works fine with 10.6.3

* no apparent changes in 10.6.3 (besides some bug fixes)

 

update 2009/11/10 (still version 0.2):

* note: version 0.2 works fine with 10.6.2

* change in 10.6.2: "# of compute units" on all current nvidia cards is now displayed as "# of cores / 8" which actually reflects the hardware in a better way, since 1 compute unit/sp cluster/multiprocessor == 8 cores.

 

update 2009/08/26 (version 0.2):

* fixed a dumb bug if a device only supports one extension (-> amd/ati devices should at least print out cl_APPLE_gl_sharing now)

* seperate device lists for opencl-only and shared opencl+opengl contexts

* better cpu/host memory detection

* works with 10A432

* updated cl.hpp

 

update 2009/06/30:

* prints out platform info

* works with 10A394

* updated cl.hpp

 

download:

oclinfo_0.2.zip

Is this really necessary? It's common knowledge now that only 8x00 and higher NVIDIA GPU's are compatible, as well as the ATI GPU's.

 

Says the man with a Pentium 4 and 7600GS GPU. ;)

 

It's just something to play around with in Snow. :P

hm, apparently some posts went missing :>

why are founds itn64 & fp64 in atom proc???

fp64/double-precision is supported by intel since 80387 times ;)

dunno about the int64 stuff, maybe it gets emulated by the driver or a quirk in apples driver/detection.

 

dyld: unknown required load command 0x80000022

Trace/BPT trap

it only works in snow leopard

Good work,

it would be interresting to see the result on a pc or a macpro with 2 Graphic cards, if opencl found them both, that mean that snow leopard will can use the both GPU, whether it is a ati or nvidia chipset, to improve applications including games (a kind of crossfire/SLI ???)

it does ... but i don't know if a shared opengl + opencl context is possible with both cards+cpu

hi, cmf

 

oclinfo don't work anymore with the last version of snow leopard 10a394 (0 OpenCL devices found!), Perhaps your utility needs to be updated

yep, done ;)

 

there were some api changes and the direct approach for getting device info didn't work anymore (querying clGetContextInfo with CL_CONTEXT_DEVICES returns nothing on 10A394). have to get this info via the platform now. thats why i also added the platform info print out.

Does your ATI 4850 work with snow leopard to get QE/CI ?

What injectors / patches do you use ?

(ATI 4850) Works using ATI_Motmot.kext from 10.5.7 and Natit.

Thanks !

 

In which .kext are that plugins (like MotMot, Triakis, Megadolon,...) ?

I cant find the ATINDRV.kext / ATIRNDRV.kext in my Snow Leo Extemsiond. Its only in 10.5.7.

Should i use that or is something wrong with my Snow Install (ATINDRV.KEXT also not in the Snow Install .plgs).

 

Sorry for little off topic - but may help others too :(

Why am I only getting 2 compute units on my CPU?

 

L2 cache size also appears to be incorrect, it should read 12 MB (not 6):

Are there any Apps / Demos out for SL which use / demonstrate OpenCL (Speed) ?

Thanks

I own NV 9600GT (sold ATI 3850) and be happy with SL 411.
