    Re: I don't know this error.

    ptxas ptx input, line 59; fatal : Parsing error near ';': syntax error

    is the error. You could try to comment out the line 59 (and related) to see, if this "solve" the error.
    When I count...
  2. Re: Iterations And GlobalRange Difficulty (Related?)

    A global size of something with 140 MB is allowed. The constant is limited to 64k and the local related to the chip between 16 and 32k.

    I had the similar problem when using too large loops. So my...

    Re: OpenCL on CPU

    Thats corrent. You need to install the ATI drivers (stream 2.0.1) to use the CPU with OpenCL. I don't know, if you need a ATI card for the installation, but for later working on CPU a ATI card is not...

    Re: Troubles with clBuildProgram...

    Use clGetProgramBuildInfo(program, device, CL_PROGRAM_BUILD_LOG, ....) to get more Info about the Build. I do this even for successfull build to get all warning.

    Re: Is this caused by memory contention?

    If you use

    __kernal void func(__constant int* cInts, __local int* lInts)
    you set the parameter into local or constant mem. Local mem is given just as cl_int parameter, which defines the size to...

    Re: Is this caused by memory contention?

    Where is the lookup table located ? It should be in the __local memory part or __constant. __local if you write them in the thread, else use constant (more space and could be given by the caller)...

    Re: Hardware details

    Ok, so I need to do the chip by chip search.
    It would be easier with an related list. so I didn't now in first place, that the local mem of the ATI 4350 is located in global mem, not in local sRam....

    Hardware details

    Hi there,

    I search for a list of graphic chip features. I want to know what features each chip has, like cores, local mem (where and how much) constant mem and so on. If no one knows, maybe we...

    Re: error -30 buildprogram

    I made up a std::map with the id and the string, and use this whenever I have an error. Easy to make with some copy/paste from the cl.h
  10. Re: What about OpenCL support for SLI or CrossfireX interconnec?

    As I see this, each Chip is interpreted as one device, regardless of intercard connection. With my 9800 GX2 each of both chips are represented as one device.
    Even in SLI mode (gaming), each chip...
  11. Re: are DUAL graphics cards supported? Anyone using this?

    Hmm, I'm using a 9800GX2, two chips on one card. If this counts. Each chip is listened as one device.
  12. Re: Reliable device identifier for caching binary

    How about Devices of a dual GFX card like GT 9800 GX2 ? Both Chips have the same informations.

    Edit : Just don't read this... didn't read all of this thread properly
  13. Re: invalid address space for argument to _kernel function

    Seem like it couldn't handle spaces in the include path.
    Better use / (windows this is valid too, could help when develop multiplatform).
    So you need an include path without any spaces in the name.
  14. Re: Compile messaged from NVidia OpenCl compiler on Windows

    The returning status value does give you more information than just *Failed*. Try to give it to the log (cout), so you could have a look into the cl.h to see, what this error means. I get a -5, what...

    Re: Out of resources problem

    this would be pretty bad. I could break it down (throw away the 100x loop). But the other loops are needed (really) and I need to do this often. Its a small calculation, need to be done very...
  16. Re: invalid address space for argument to _kernel function

    the vector class is part of the STL of C++. The CL compiler do not know any STL stuff (cause it is an OpenCL compiler, not C++)

    I've the latest driver on board (196 Beta), also current Nexus.
    The loops are 100 * 12000 * 500 = 60Mio within one core.

    Re: NVIDIA + ATI hardware in the same Computer

    Thank you very much. This seem to solve most of my problem. Seem to be the OpenCL Dll of nv, which doesn't let the ATI stuff working. Still one device is missing. But this is an NVidia device.
