Computer experiments are often performed to allow modeling of a response surface of a physical experiment that can be too costly or difficult to run except using a simulator. Running the experiment over a dense grid can be prohibitively expensive, yet running over a sparse design chosen in advance can result in obtaining insufficient information in parts of the space, particularly when the surf...

BlueGene/L is a massively parallel supercomputer that is currently the fastest in the world. Implementing MPI, and especially fast collective communication operations can be challenging on such an architecture. In this paper, I will present optimized implementations of MPI collective algorithms on the BlueGene/L supercomputer and show performance results compared to the default MPICH2 algorithm...

We describe the key role played by partial evaluation in the Supercomputer Toolkit, a parallel computing system for scientiic applications that eeectively exploits the vast amount of parallelism exposed by partial evaluation. The Supercomputer Toolkit parallel processor and its associated partial evaluation-based compiler have been used extensively by scientists at M.I.T., and have made possibl...

In the past three years, the Perfect Benchmark TM Suite has evolved from a supercomputer performance evaluation plan, presented by Kuck and Sameh at the 1987 International Conference on Supercomputing, to a vigorous international activity. This paper surveys the current state of supercomputer performance evaluation with particular focus on the methodology adopted by the Perfect eeort. While the...

Comprehensive research data are acknowledged as a necessity for acceleration. Research institutes and universities engaged in developing management systems. The National Agriculture Food Organization of Japan (NARO) developed NARO-linked databases (Narolin DBs) addition to supercomputer. In the Narolin DB various on agriculture cataloged using common metadata. relationship between complicated n...

With the goal of demonstrating the advantages of supercomputer simulations for process design and operations, Bayer AG recently teamed up with Cray Research to perform plantwide dynamic simulations of an entire Bayer production facility in Leverkusen. This paper presents project results and benefits from both a computational standpoint and a Bayer company perspective. Regarding computational as...

Although supercomputer-class performance is a necessity for many research applications, the supercomputer's high price tag places it far beyond the reach of most academic and industrial organizations. In addition, traditional shared-memory architectures, whether single-processor or multiprocessor, are rapidly approaching their performance limits. This paper describes Intel's new iPSC family-mul...

A strategy is proposed for the development of algorithms and software for Exaflops supercomputers. The strategy contains three stages. The first stage is the co-design, which is defined as considering the architecture of the supercomputer at all stages of the development of the code. The second is the forward-looking development of algorithms and software for the most promising Exaflops superco...
