PyOpenCL lets you access GPUs and other massively parallel compute devices from Python. It tries to offer computing goodness in the spirit of its sister project PyCUDA:

  • Object cleanup tied to lifetime of objects. This idiom, often called RAII in C++, makes it much easier to write correct, leak- and crash-free code.
  • Completeness. PyOpenCL puts the full power of OpenCL's API at your disposal, if you wish. Every obscure get_info() query and all CL calls are accessible.
  • Automatic Error Checking. All CL errors are automatically translated into Python exceptions.
  • Speed. PyOpenCL's base layer is written in C++, so all the niceties above are virtually free.
  • Helpful and complete Documentation as well as a Wiki.
  • Liberal license. PyOpenCL is under the MIT license and free for commercial, academic, and private use.
