  1. Parallel Reduction combined with other Operations

    I am trying to write a function that performs a few vector operations, which are followed by a reduction operation.

    However, I am confused how I go about incorporate the parallel reduction...
  2. Multiple kernel invocations within kernel or via host


    I want to chain together multiple kernels, but is it better to call the kernel functions from within a kernel or via the host.

    Pseudo code below:
    Kernel calling kernel

    __kernel void...
  3. Nested loops with dependancies and series operations

    I have a solver written in FORTRAN, which I would like to port to OpenCL. The solver contains several nested inter-dependent loops on the same level separated by serial operations(see pseudo code).
  4. The following Exceptions have occurred : clEnqueueNDRangeKernel(-54)

    I get the exception clEnqueueNDRangeKernel(-54) when the command trapeziodal(cl::EnqueueArgs(queue, cl::NDRange(subIntervals), cl::NDRange(local_trapeziodal)), d_x, d_fx, d_intervals, subIntervals);...
