    Two small problems in Appendix D.3

    Hi,

    In the first line of the body of the kernel for appendix D.3 there is an extra ')' which causes it not to compile.

  2. Re: Is possible to porting opencl to other systems by myself

    Absolutely, everything you need to know to implement OpenCL is contained in the standard, which is freely available. There are one or two areas where things are a touch ambiguous or unclear, but...

    I don't actually have snow leopard here, so I'm guessing, but

  7. Re: Why does OpenCL define 'bool' but does not define '_Bool'?

    I'm guessing here that the rationale was that without the legacy code to worry about that C99 had they might as well give it the sensible name that would have been used if C had bool from the start.
  8. Re: Timeline for a future cluster/cloud extension?

    You might be interested in http://sourceforge.net/projects/clumpi/, it presents MPI nodes as a single device.

    It's not a complete, conforming implementation by any means yet and clearly there is...
