"Parallel computing in N dimensions made easy"
pnumpy is a very lightweight implementation of distributed arrays,
which runs on architectures ranging from multi-core laptops to large
MPI clusters. pnumpy is based on numpy and mpi4py and supports arrays in
any number of dimensions. Processes can access remote data using a "get"
method. This can be used to access neighbor ghost data but is more
flexible as it allows to access data from any process--not necessarily
a neighboring one. pnumpy is designed to work seamlessly with numpy's
slicing operators ufunc, etc., making it easy to transition your code
from using numpy arrays to pnumpy arrays.
Getting pnumpy
--------------
Stable versions of pnumpy can be accessed and installed using
$ [sudo] pip install pnumpy
or
$ [sudo] easy_install pnumpy
The latest source version can be accessed anonymously from the sourceforge site
using the command:
$ svn co https://svn.code.sf.net/p/pnumpy/code/trunk pnumpy
Building pnumpy by hand
-----------------------
pnumpy needs python 2.x, mpi4py, and numpy. To install pnumpy type:
$ [sudo] python setup.py install
or
$ python setup.py install --prefix=<install_directory>
if you wish to install pnumpy under install_directory (make sure
to set the PYTHONPATH environment variable to
<install_directory/lib/python<version>/site-packages).
Documentation
-------------
Please visit https://sourceforge.net/p/pnumpy/wiki/Home/ for examples showing
how to use pnumpy.
Testing
-------
$ cd tests
$ mpiexec -n 4 python testDistArray.py (or any other test)
Contact
-------

reports, questions, and request for additional features.
