PyORBit is a Python binding for the ORBit2 CORBA ORB. It was developped to suit the needs of the bonobo bindings in GNOME-Python, but is usable for other purposes as well. It aims to follow the standard Python language mapping for CORBA. It can generate stubs at runtime from typelibs, IDL files, or by introspecting remote objects using ORBit2's IModule typelib capabilities.
Pypvm is a Python module which allows interaction with the Parallel Virtual Machine (PVM) package. PVM allows a collection of computers connected by a network to serve as a single parallel computer. This package allows Python programs to do almost anything that is possible for Fortran or C programs, including starting and stopping other programs, sending them messages, and accessing cluster-wide data stores.
