A fast-growing number of high-layer protocols, services and networked applications has been run over computer networks and needs to be managed. A unified, decentralized framework should be used to scale for the current large and complex computing environments. Besides, the management environment should be quickly and easily adaptable to monitor dynamic scenarios. This paper presents the Trace M...

The Futures Lab was founded within the Mathematics and Computer Science Division of Argonne National Laboratory in the fall of 1994. The goal of the lab is develop new technology and systems to support collaborative science. In order to meet this goal, the lab is organized around three research areas: advanced networking, multimedia, and virtual environments. The Argonne Computing and Communica...

We describe a general purpose master-worker parallel computation Python module called PyMW. PyMW provides a unified interface to multiple computation environments including multicore processors, networked clusters and the Berkeley Open Infrastructure for Network Computing (BOINC) software platform. PyMW is intended to support rapid development, testing and deployment of large scale master-worke...

An extended model for networked control systems is developed by integrating a networked control systems and a communication network model. This results in a deterministic switching system. Stability analysis of the integrated system is then investigated using switched system theory. Specifically, sufficient conditions for global exponential stability of the systems are given in terms of plant a...

Many systems on our planet are known to shift abruptly and irreversibly from one state another when they forced across a "tipping point," such as mass extinctions in ecological networks, cascading failures infrastructure systems, social convention changes human animal networks. Such regime demonstrates system's resilience that characterizes the ability of system adjust its activity retain basic...

Abstract A Networked Music Performance (NMP) is defined as what happens when geographically displaced musicians interact together while connected via network. The first NMP experiments begun in the 1970s, however, only recently development of network communication technologies has created necessary infrastructure needed to successfully create an NMP. Moreover, widespread adoption network-based ...

How do we understand the performance of a networked system? Some of the possibilities are: 1. Model the system as a mathematical problem, and derive a closed-form analytical expression for its performance. 2. Model the system as a mathematical problem that can not be solved in terms of a closed-form expression, and use numeric computations to calculate the solution at the points of interest. 3....

Multicore computer systems are adopting more cores to meet the increasing performance requirement. Network topology to make communication in such a multicore/manycore system (like Intel 80-Core Research Chip and IBM Roadrunner) is extremely important to achieve high performance by supplying low energy. Designing and analysing such a gigantic system is very complicated and it costs up to million...
