opencl-for-python 0.4.0

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]
