Distributed Computing, a reality unfolding



Optical Networking Protocol
“High-speed, on-demand, application-initiated provisioning of bandwidth is also what the grid computing community is demanding,” Stevenson said. Grids connect heterogeneous computing platforms so that they operate, and appear to the user, as a single computing system. This means that computational problems can be directed to a system within the grid that will process it in the quickest and most cost effective manner. Grid computing provides users with unprecedented computing power, services and information, combing the resources of heterogeneous computing resources no matter where they are located.

“Grid resource requirements of big science applications, such as particle physics, are very dynamic,” said Stevenson. “The goal for sparse networks like ATDnet, and the recently announced National Lamda Rail, is to share grid bandwidth the same way you share computing cycles and storage in the grid. You also want to use those resources efficiently. These applications often involve computational steering and cannot afford the latency associated with electronic routers. The applications may require 300 megabits per second, but that’s only a small percentage of a 10-gigabit optical channel. JIT lets you share the remaining 97 percent of that bandwidth with others on the grid without the reduced performance inherent with electronic routing.” MCNC and the University of North Carolina 16-campus system are jointly developing a statewide grid computing network for North Carolina’s higher education community using the existing statewide North Carolina Research and Education Network, operated by MCNC. The statewide research and education grid will link computing and data resources from multiple institutions in multiple locations with the potential to vastly increase the resources available to individual institutions. When complete, North Carolina will be one of the first states in the nation to deploy a statewide grid infrastructure.

Another article that touches on grid computing (distributed computing) talks primarily about the seti@home program but also is proof that similar technology could be used for the benifit of Freenet. Apparent to me in the first article was who were the chief investors (military) and how they were going to use it, but one could see how this technology could also compute algorithms in real time to defeat cencorship filters or maybe harness massive DoS potential against opposing unethical viewpoints. Sort of a Electronic Blockade (I'm capatalizing because I might have coined it here first :-)
