Pypvm is intended to be an educational and prototyping tool.
The primary authors of Pypvm are W. Michael Petullo, who can be contacted at email@example.com, and Greg Baker, who can be contacted at firstname.lastname@example.org , and Sam Tannous, who can be contacted at email@example.com . There is just one mailing-list at the moment, which is hardly ever used: firstname.lastname@example.org
The usual story applies: gunzip and tar xvf the file, or use whatever tools read .tar.gz files on your operating system. Then read the INSTALL and README files, which should be sufficiently informative.
It has only been tested on Linux/x86 and Linux/PPC, although there is no reason to expect it wouldn't work on anything else.
There is a CVS web interface -- development is quite slow, though, so this isn't heavily used.
Greg Baker patched pvmmodule.c to work with PVM3.3.11 & Python1.5 in 1997 and 1998. No attempt was made to be backwardly compatible. PyPVM version 0.12 was released in June 1998. It was based on the output of swig and heavily cleaned up. It then suffered considerable bit-rot as Greg stopped working on it actively.
W. Michael Petullo independantly developed a complete set of bindings for PVM3.4 (with which PyPVM did not work well). He called this pypvm. Version 0.8.7 was released in November 1999.
In May 2000, the two projects merged into one, still called pypvm. This was version 0.90.
Version 0.91 fixes some bugs, and version 0.92 adds support for python 2.1. Version 0.94 adds support for python 2.3.
