opencl-for-python (original) (raw)

Project description

This is yet another set of Python bindings for OpenCL.

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]
