Programmers of concurrent applications are faced with a complex performance space in which data distribution and concurrency management exacerbate the difficulty of building large, complex applications. To address these challenges , the Illinois Concert system provides a global names-pace, implicit concurrency control and granularity management , implicit(More)
Airborne links are playing an increasingly important role in defense and military scenarios. This makes it important to investigate the performance of existing transport protocols over such links. Airborne links experience high variation in quality due to mobility, weather and other effects such as blockage.This translates to high loss rate environments for(More)
Programmers of concurrent applications are faced with complex performance trade-oos, since data distribution and concurrency management exacerbate the diiculty of building large, complex applications. To address these challenges, the Illinois Concert system provides a global namespace, implicit concurrency control and granularity management, implicit(More)
In this thesis we present analysis of Optical Flow Switching (OFS), an architectural approach for enabling all-optical user to user connections for transmission of Internet traffic. We first describe a demonstration of OFS on the ONRAMP test environment which is a MAN optical network implemented in hardware in the Boston geographic area. This demonstration(More)
Structured Adaptive Mesh Reenement (SAMR) simulation methods are attractive because they can increase computational eeciency dramatically. However, their irregular and less predictable computational and data structure makes them challenging to parallelize eeciently on large-scale parallel machines. We use the Illinois Concert C++ system (which supports(More)
We have used the Illinois Concert C++ system (which supports dynamic, object-based parallelism) to parallelize a exible adaptive mesh reenement code for the Cosmology NSF Grand Challenge. Out goal is to enable programmers of large-scale numerical applications to build complex applications with irregular structure using a high-level interface. The key(More)
Overview of the research in the Communications and Networking Group Research in the group includes topics on networks and communication systems. The work extends to applications in satellite, wireless and optical communication, and data networks. The objective is to develop the scientific base needed to design data communication networks that are efficient,(More)
