Although researchers can develop software on small, local clusters and move it later to larger clusters and supercomputers, the software must run efficiently in both environments. Two efforts aim to improve the efficiency of scientific computation on clusters through resource-aware dynamic load balancing. The popularity of cost-effective clusters built from(More)
Decision makers, faced with highly complex alternatives for protecting our nation's critical infrastructures must understand the consequences of policy options before they enact solutions to prevent and mitigate disasters. An effective way to examine these tradeoffs is to use a computer simulation that integrates high level representations of each(More)
