Welcome to OpenCL for Python's documentation!

This is yet another set of Python bindings for OpenCL.

Warning

This project currently is in a beta release state.

Features:

• Python 2 and Python 3 compatibility.

• Supports OpenCL 1.1

• Discoverable properties and methods:

  No more ctx.get_info(pyopencl.context_info.DEVICES) just do ctx.devices

• Tight integration with ctypes:

  import opencl as cl
  from ctypes import c_float
  ctx =  cl.Context()
  a = cl.empty(ctx, [2, 3], ctype=c_float)
  

• Call kernels like a python function with defaults and keyword arguments:

  import opencl as cl
  from ctypes import c_float, c_int
  
  source = '__kernel void foo(__global float*a, int b, float c) ...'
  ...
  # Create a program and context
  
  foo = program.foo
  foo.argnames = 'a', 'b', 'c'
  foo.argtypes = cl.global_memory(c_float, ndim=2), c_int, c_float
  # Equivalent to def foo(a, b=1, c=2.0):
  foo.__defaults__ = 1, 2.0
  
  event = foo(queue, a)
  

• Memory objects support indexing and slicing:

  mem2 = memobj[:, 1, :-1]
