Any suggestion? The constants are available if you compile against an OpenCL 2+ ICD loader (the libOpenCL.so and its corresponding header file). (ocl-icd or the Khronos one work well) The bigger issue is that clCreateCommandQueueWithProperties isn't currently wrapped. I've created an issue for that: https://github.com/inducer/pyopencl/issues/198 I'd be happy to take a patch.

[PyOpenCL] How to set device side queue size in pyopencl?
In the Intel opencl 2.0 tutorial resource Sierpi??ski Carpet, they use the device side enqueue properties added in opencl 2.0. In the source code, there is a segment like this: // You need to create device side queue for enqueue_kernel to work // We set the device side queue to 16MB, since we are going to have a large // number of enqueues cl_queue_properties qprop[] = {CL_QUEUE_SIZE, 16*1024*1024, CL_QUEUE_PROPERTIES, (cl_command_queue_properties)CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE | CL_QUEUE_ON_DEVICE | CL_QUEUE_ON_DEVICE_DEFAULT, 0}; cl_command_queue my_device_q =clCreateCommandQueueWithProperties(CLU_CONTEXT, cluGetDevice(CL_DEVICE_TYPE_GPU), qprop, &status); Now I want to use pyopencl to rewrite the code in python to learn dynamic parallelism method. But I can't find any instruction to set the queue size as the code shows. The CommandQueue API has the properties option, but in the document these options/values don't include size.
