opencl-for-python 0.5.2

Python 2和Python 3兼容性。

支持OpenCL 1.1

可发现属性和方法

不再需要 ctx.get_info(pyopencl.context_info.DEVICES)，只需做 ctx.devices

与ctypes紧密集成

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

像Python函数一样调用内核，具有默认参数和关键字参数

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)

内存对象支持索引和切片

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