Idle waves in high-performance computing

Adaptive parallelism with RMI: Idle high-performance computing resources can be completely avoided

In practice, standard scheduling of parallel computing jobs almost always leaves significant portions of the available hardware unused, even with many jobs still waiting in the queue. The simple reason is that the resource requests of these waiting jobs are fixed and do not match the available, unused resources. However, with alternative but existing and well-established techniques it is possib...

High-Performance Computing in Industry

In 1993, a list of the top 500 supercomputer sites worldwide was made available for the rst time. Since then, the Top500 list has been published twice a year. The list allows a detailed and well-founded analysis of the state of high-performance computing (HPC). This article summarizes the recent trends in application areas of HPC systems, focusing on the increase in industrial installations and...

Trends in High-Performance Computing

The Annual Boole Lecture was established and is sponsored by the Boole Centre for Research in Informatics, the Cork Constraint Computation Centre, the Department of Computer Science, and the School of Mathematics, Applied Mathematics and Statistics at University College Cork. The series is named in honour of George Boole, the first professor of Mathematics at UCC, whose seminal work on logic in...

High-Performance Commodity Computing

In this chapter, we consider the role of commodity off-the-shelf software technologies and components in the construction of computational grids. We take the position that computational grids can and should build on emerging commodity network computing technologies, such as the CORBA, COM, JavaBeans, and less sophisticated Web and networked approaches. These technologies are being used to const...
