Lilith is a general purpose tool that provides a highly scalable, easy distribution of user code across a heterogeneous computing platform. By handling the details of code distribution and communication such a framework allows for the rapid development of tools for the use and management of large distributed systems. This speed-up in development not only enables the easy creation of tools as needed but also facilitates the ultimate development of more refined, hard-coded tools as well. Lilith is written in Java, providing platform independence and further facilitating rapid tool development through object reuse and ease of development. We present the user-involved objects in the Lilith Distributed Object System and the Lilith User API. We present an example of tool development, illustrating the user calls, and present results demonstrating Lilith's scalability.

Lilith is a general purpose tool to provide highly scalable, easy distribution of user code across a heterogeneous computing platform. Lilith's principal task is to span a heterogeneous tree of machines executing user-defined code in a scalable and secure fashion. Lilith will be used for controlling user processes as well as general system administrative tasks. Lilith is written in Java, taking advantage of Java's platform independence and intent to move code across networks. The design of Lilith provides hooks for experimenting with tree-spanning algorithms and security schemes. We present the Lilith Object model, security scheme, and implementation, and present timing results demonstrating Lilith's scalable behavior.
