PyLinda V0.4
Linda is an widely studied distributed computing environment, centered around the notion of a tuple space. A tuple space is a bag (also called a multi-set) of tuples. A tuple is an ordered, typed chunk of data. Tuple spaces exist independently of processes in the system, and the data placed into a tuple space also exist independently. See "Generative communication in Linda" (1985) and "Multiple tuple spaces in Linda" both by David Gelernter for more information on Linda.
PyLinda is a simple implementation of a linda system, however it also includes several of the more recently proposed extensions to Linda in the form of multiple tuple spaces, garbage collection, sane non-blocking primitives and bulk tuple operations.
For installation instructions see the "How To Install" page.
Firstly you need to create a network of one or more Linda servers. This can be done by executng the following command on one node of the network. linda_server.py
and then executing
linda_server.py -c<ip address or dns name>
on each of the other nodes where the ip address or dns name is for a node where the server has already been started. For a more detailed view on how to run the server see "Running The Server" .
On any of the computers that have a server started you can then start Python.
>>> import linda
>>> linda.connect()
>>> linda.universe._out((1, 2, 3))
>>> linda.universe._in((1, 2, int))
(1, 2, 3)
- Note:
- For details on how to write a program to take advantage of the linda system see the tutorial page.
For more detailed examples look at the examples section.
