CL_INVALID_ARG_SIZE error

Tweet

CL_INVALID_ARG_SIZE caused by OpenCL's clSetKernelArg

For example,
ret = clSetKernelArg(kernel, 0, sizeof(size_t), &n);

Kernel's sizeof(size_t) (for example, 8 byte) and host's sizeof(size_t) (for example, 4 byte) might be different. Compile your program in 64bit if you installed OpenCL 64bit.
