NSIM: An Interconnection Network Simulator for Extreme-Scale Parallel Computers

NSIM: An Interconnection Network Simulator for Extreme-Scale Parallel Computers

In the near future, interconnection networks of massively parallel computer systems will connect more than a hundred thousands of computing nodes. The performance evaluation of the interconnection networks can provide real insights to help the development of efficient communication library. Hence, to evaluate the performance of such interconnection networks, simulation tools capable of modeling...

Interconnection Networks for Large - Scale Parallel Computers

A new scalable interconnection topology called the Spanning Multichannel Linked Hypercube (SMLH) is proposed along with an optical implementation methodology that combines both the advantages of free space optics with those of wavelength division multiplexing techniques. The SMLH uses the hypercube topology as a basic building block and connects such building blocks using two-dimensional multic...

Recursive Diagonal Torus: An Interconnection Network for Massively Parallel Computers

ÐRecursive Diagonal Torus (RDT), a class of interconnection network is proposed for massively parallel computers with up to 2 nodes. By making the best use of a recursively structured diagonal mesh (torus) connection, the RDT has a smaller diameter (e.g., it is 11 for 2 nodes) with a smaller number of links per node (i.e., 8 links per node) than those of the hypercube. A simple routing algorith...
