NetWorkSpaces makes it easy to create and experiment with parallel programs without requiring specialized tools or hardware. You must install both the NetWorkSpaces server (on one machine) and the R NetWorkSpaces package (on all machines involved in the computation). The server is implemented using Python and Twisted (a Python package), which are required. To download and install the server, go to the R NetWorkSpaces project on Source Forge at http://sourceforge.net/projects/nws-r.
A commercial version of NetWorkSpaces which has additional fault tolerance features is available as part of REvolution Computing's ParallelR product. More information is available at http://www.revolution-computing.com/revolution/web/static/products.
