Compyle allows users to execute a restricted subset of Python (almost similar
to C) on a variety of HPC platforms. Currently we support multi-core CPU
execution using Cython, and for GPU devices we use OpenCL or CUDA.
Users start with code implemented in a very restricted Python syntax, this code
is then automatically transpiled, compiled and executed to run on either one CPU
core, or multiple CPU cores (via OpenMP_) or on a GPU. Compyle offers
source-to-source transpilation, making it a very convenient tool for writing HPC
libraries.
Some simple yet powerful parallel utilities are provided which can allow you
to solve a remarkably large number of interesting HPC problems. Compyle also
features JIT transpilation making it easy to use.
Documentation and learning material is also available in the form of:
- Documentation at: https://compyle.readthedocs.io
- An introduction to compyle in the context of writing a parallel molecular
dynamics simulator is in our `SciPy 2020 paper
<http://conference.scipy.org/proceedings/scipy2020/compyle_pr_ab.html>`_.
- `Compyle poster presentation <https://docs.google.com/presentation/d/1LS9XO5pQXz8G5d27RP5oWLFxUA-Fr5OvfVUGsgg86TQ/edit#slide=id.p>`_
- You may also try Compyle online for free on a `Google Colab notebook`_.
While Compyle seems simple it is not a toy and is used heavily by the PySPH_
project where Compyle has its origins.

Installation
-------------
Compyle is itself largely pure Python but depends on numpy_ and requires
either Cython_ or PyOpenCL_ or PyCUDA_ along with the respective backends of a
C/C++ compiler, OpenCL and CUDA. If you are only going to execute code on a
CPU then all you need is Cython.
You should be able to install Compyle by doing::
$ pip install compyle
.. _PyOpenCL: https://documen.tician.de/pyopencl/
.. _OpenCL: https://www.khronos.org/opencl/
.. _Cython: http://www.cython.org
.. _numpy: http://www.numpy.org
.. _OpenMP: http://openmp.org/
.. _PyCUDA: https://documen.tician.de/pycuda/
A simple example
----------------
Here is a very simple example::
from compyle.api import Elementwise, annotate, wrap, get_config
import numpy as np
@annotate
def axpb(i, x, y, a, b):
y[i] = a*sin(x[i]) + b
x = np.linspace(0, 1, 10000)
y = np.zeros_like(x)
a, b = 2.0, 3.0
backend = 'cython'
get_config().use_openmp = True
x, y = wrap(x, y, backend=backend)
e = Elementwise(axpb, backend=backend)
e(x, y, a, b)
This will execute the elementwise operation in parallel using OpenMP with
Cython. The code is auto-generated, compiled and called for you transparently.
The first time this runs, it will take a bit of time to compile everything but
the next time, this is cached and will run much faster.
If you just change the ``backend = 'opencl'``, the same exact code will be
executed using PyOpenCL_ and if you change the backend to ``'cuda'``, it will
execute via CUDA without any other changes to your code. This is obviously a
very trivial example, there are more complex examples available as well.
