Seattle Conference on Scalability: High Performance Computin

Google Tech Talks June 14, 2008 ABSTRACT Increasingly, R users have access to multiprocessor machines or multiple-core CPUs. However, base R does not natively support parallel processing; this can force R users to wait while computationally intensive work is done on a single processor or core and other processors or cores lie idle. NetWorkSpaces for R (NWS-R) is a Python-based tuple coordination system that is portable across virtually all popular computing platforms. NWS-R includes a web interface that displays the workspaces and their contents; this is helpful when debugging or developing a program, or monitoring the progress of an application. NWS-R is easy to learn, accessible from many development environments, and deployable on ad hoc collections of spare CPUs. The server and client for NWS-R are available at SourceForge (; the client is also available at CRAN ( We will present NetWorkSpaces for R and demonstrate the web interface. While we are using R as the primary example for our NetWorkSpaces product, we will also present interfaces to other languages such as python and matlab.
