OpenCL Info

[flashi]

hi all

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 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

Mit den Tool kann mann Prüfen ob die GPU und der CPU richtig erkannt wird. Mehr Infos gibt dann oben in dem englischen-sprachigen Teil.

Das sind meine Info von meinen PC:
