Lilith: Scalable execution of user code for distributed computing

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
