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?

[sejabs.2016]

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, );
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. Any suggestion?___

[PyOpenCL] How to set device side queue size in pyopencl?

[sejabs.2016]

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, );
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. Any suggestion?___
