PyOpenCL: Pythonic Access to OpenCL, with Arrays and Algorithms --------------------------------------------------------------- .. image:: https://gitlab.tiker.net/inducer/pyopencl/badges/master/pipeline.svg :target: https://gitlab.tiker.net/inducer/pyopencl/commits/master .. image:: https://badge.fury.io/py/pyopencl.png :target: http://pypi.python.org/pypi/pyopencl .. image:: https://travis-ci.org/inducer/pyopencl.svg?branch=master :target: https://travis-ci.org/inducer/pyopencl (Travis only builds binary wheels for releases, see `#264 `_) 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 open-source under the `MIT license `_ and free for commercial, academic, and private use. * Broad support. PyOpenCL was tested and works with Apple's, AMD's, and Nvidia's CL implementations. Simple 4-step `install instructions `_ using Conda on Linux and macOS (that also install a working OpenCL implementation!) can be found in the `documentation `_. What you'll need if you do *not* want to use the convenient instructions above and instead build from source: * gcc/g++ new enough to be compatible with pybind11 (see their `FAQ `_) * `numpy `_, and * an OpenCL implementation. (See this `howto `_ for how to get one.) Places on the web related to PyOpenCL: * `Python package index `_ (download releases) * `Documentation `_ (read how things work) * `Conda Forge `_ (download binary packages for Linux, macOS, Windows) * `C. Gohlke's Windows binaries `_ (download Windows binaries) * `Github `_ (get latest source code, file bugs) * `Wiki `_ (read installation tips, get examples, read FAQ)
