From leon Tue Feb 26 13:52:39 2002 Date: Wed, 13 Feb 2002 16:28:45 -0500 (EST) From: Leon Poutievsk To: Netseminar Subject: Network seminar, Thursday, 2pm Our next Network seminar is on Thursday, February 14th at 2pm. Tim Mattox will talk about Flat Neighborhood Networks. If you would like to give a talk on our seminar please contact me, we have several spots available. Speaker: Tim Mattox, Ph.D. student, Electrical and Computer Engineering, UK Place: Verizon Room, on the 1st floor of the Hardymon Building Time: Thursday, February 14th, 2:00-3:00pm Flat Neighborhood Networks Parallel supercomputers have been designed and built since the early days of computing, from the Illiac-IV in the 60's, to the modern beowulf cluster. The engineering tradeoffs on communication costs and performance have led to many supercomputer network architectures over the decades: from rings, meshes, hypercubes, trees, to fat-trees. This talk will cover a groundbreaking new supercomputing network architecture called a Flat Neighborhood Network (FNN). FNNs provide low latency and high bisection bandwidth for very low cost, outperforming fat-trees which had been considered one of the best, if not the best, universal supercomputer network architecture. Invented/discovered at the University of Kentucky in early 2000, FNNs have garnered world wide recognition. The fundamental properties of FNNs, and their ultimate performance limits are still being explored.
