Exploring the Energy-Time Tradeoff in MPI Programs on a Power-Scalable Cluster
Recently, energy has become an important issue in highperformance computing. For example, supercomputers that have energy in mind, such as BlueGene/L, have been built; the idea is...

Improvement of Power-Performance Efficiency for High-End Computing
Left unchecked, the fundamental drive to increase peak performance using tens of thousands of power hungry components will lead to intolerable operating costs and failure rates. R...

An Antisocial Strategy for Scheduling Mechanisms
Previous work on task scheduling mechanisms assumed that the agent’s goal is to maximize its own profit without considering the effect of its strategy on the other agents’ pr...

A Distributed Chained Lin-Kernighan Algorithm for TSP Problems
The Chained Lin-Kernighan algorithm (CLK) is one of the best heuristics to solve Traveling Salesman Problems (TSP). In this paper a distributed algorithm is proposed, were nodes i...

Effective Instruction Prefetching via Fetch Prestaging
As technological process shrinks and clock rate increases, instruction caches can no longer be accessed in one cycle. Alternatives are implementing smaller caches (with higher mis...

On the Scalability of Centralized Control
Scalability of clusters and MPPs is typically discussed in terms of limits on growth: something which grows at a rate of O(log p) (where p is the number of processors) is said to ...
