Component specification in the Cactus Framework: The Cactus Configuration Language

Gabrielle Allen, Tom Goodale, Frank Loffler, David Rideout, Erik Schnetter, Eric L. Seidel
2010 2010 11th IEEE/ACM International Conference on Grid Computing  
In this paper, we discuss the Cactus Configuration Language (CCL) which is used to describe components ("thorns") in the Cactus Framework.  ...  Component frameworks are complex systems that rely on many layers of abstraction to function properly.  ...  Cactus currently operates with a single computational grid so that all physical models need to run on a single domain.  ...

Impact of modern memory subsystems on cache optimizations for stencil computations

Shoaib Kamil, Parry Husbands, Leonid Oliker, John Shalf, Katherine Yelick
2005 Proceedings of the 2005 workshop on Memory system performance - MSP '05  
First we develop a simple benchmark to evaluate the effectiveness of prefetching in cache-based memory systems.  ...  In this work we investigate the impact of evolving memory system features, such as large on-chip caches, automatic prefetch, and the growing distance to main memory on 3D stencil computations.  ...  It is also important to understand the range of grid sizes currently being utilized in large-scale scientific applications.  ...
