Load-Balancing Iterative Computations in Heterogeneous Clusters With Shared Communication Links

Tags:
load balancing

Overview This paper is devoted to mapping iterative algorithms onto heterogeneous clusters. The application data is partitioned over the processors, which are arranged along a virtual ring. At each iteration, independent calculations are carried out in parallel, and some communications take place between consecutive processors in the ring. The question is to determine how to slice the application data into chunks, and to assign these chunks to the processors, so that the total execution time is minimized. One major difficulty is to embed a processor ring into a network that typically is not fully connected, so that some communication links have to be shared by several processor pairs.

Supercomputer rivals up the ante

Both contain around 6,000 processors and reach top speeds approaching 4 teraflops (trillion calculations per second). Two supercomputer industry heavyweights are squaring up over who makes the fastest machine, while a new contender has thrown its...

The Bloor Perspective: LinuxWorld shenanigans, Psion trouble and what value stock options

All of these follow hot on the heels of release 2.4.1 of the Linux kernel, with its improved support of multiple processors and faster execution times. At LinuxWorld, IBM's Sam Palmisano kicked things off announcing Big Blue has a 64-processor...

Prescott - The new generation of Pentium

It effectively allows a processor to behave like two virtual processors, handling two streams of instructions in parallel, speeding up the performance of multiple computing tasks by as much as 30 per cent, Intel claims.

Sun supercomputers start to purr with Wildcat

But since the mid-1990s more and more have been built out of clusters of separate systems connected with high-speed links. At the extreme of this newer trend are 'Beowulf' clusters, with dozens or hundreds of lower-powered Linux servers.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
