Hi,
Congratulations for the great framework! I can have almost all demos  from the github working.
Except RadixSort that does not compile on method putArgSize.
When I replace putArgSize by putArg, as in the before mentionned sample, I got the following exception.
How should I rework the code to have this working?
Best regards,
Martin


void radixSortBlocksKeysOnlyOCL(CLBuffer<IntBuffer> keys, int nbits, int startbit, int numElements) {

        int totalBlocks = numElements / 4 / CTA_SIZE;
        int globalWorkSize = CTA_SIZE * totalBlocks;
        int localWorkSize = CTA_SIZE;
       
        ckRadixSortBlocksKeysOnly.putArg(keys).putArg(tempKeys).putArg(nbits).putArg(startbit)
        .putArg(numElements).putArg(totalBlocks).putArg(4 * CTA_SIZE * 4)
        .rewind();
        /*ckRadixSortBlocksKeysOnly.putArg(keys).putArg(tempKeys).putArg(nbits).putArg(startbit)
                                 .putArg(numElements).putArg(totalBlocks).putArgSize(4 * CTA_SIZE * 4)
                                 .rewind();*/

        queue.put1DRangeKernel(ckRadixSortBlocksKeysOnly, 0, globalWorkSize, localWorkSize);
    }
