Login to NPACI-net's Legion context space from the web. NPACI-net is a Legion testbed based at the University of Virginia. This is an excellent way to see a working Legion system's context space from the user's point of view. If you have an NPACI-net account, you can login and start working.

The Legion Project

Key words: parallel processing, high performance, object-oriented, distributed systems, metasystems, wide area, gigabit networks

Legion is an object-based, meta-systems software project at the University of Virginia. From the project's beginning in late 1993, the Legion Research Group`s goal has been a highly useable, efficient, and scalable system founded on solid principles. We have been guided by our own work in object-oriented parallel processing, distributed computing, and security, as well as by decades of research in distributed computing systems. Our system addresses key issues such as scalability, programming ease, fault tolerance, security, site autonomy, etc. Legion is designed to support large degrees of parallelism in application code and manage the complexities of the physical system for the user. The first public release was made at Supercomputing '97, San Jose, California, on November 17, 1997.

Legion is a work in progress: our team will not finish Legion but will create an "open" system that allows and actively encourages third-party development of applications, run-time library implementations, and core system components.
