Models for Discrete Quantum Gravity
We first discuss a framework for discrete quantum processes (DQP). It is
shown that the set of q-probability operators is convex and its set of extreme
elements is found. The property of consistency for a DQP is studied and the
quadratic algebra of suitable sets is introduced. A classical sequential growth
process is "quantized" to obtain a model for discrete quantum gravity called a
quantum sequential growth process (QSGP). Two methods for constructing concrete
examples of QSGP are provided.Comment: 15 pages which include 2 figures which were created using LaTeX and

Priority-enabled Scheduling for Resizable Parallel Applications
In this paper, we illustrate the impact of dynamic resizability on parallel scheduling.
Our ReSHAPE framework includes an application scheduler that supports dynamic resizing of parallel applications. We propose and evaluate new scheduling policies made possible by our ReSHAPE framework. The framework also provides a platform to experiment with more interesting and sophisticated scheduling policies and scenarios for resizable parallel applications. The proposed policies support scheduling of parallel applications with and without user assigned priorities. Experimental results show that these scheduling policies significantly improve individual application turn around time as well as overall cluster utilization
