Efficient Input and Output for Scientific Simulations
- In Proceedings of I/O in Parallel and Distributed Systems (IOPADS
, 1999
"... Large simulations which run for hundreds of hours on parallel computers often periodically generate snapshots of states, which are later post-processed to visualize the simulated physical phenomenon. For many applications, fast I/O during post-processing, which is dependent on an efficient organizat ..."

organization of data on disk, is as important as minimizing computation-time I/O. In this paper we propose optimizations to support efficient parallel I/O for scientific simulations and subsequent visualizations. We present an ordering mechanism to linearize data on disk, a performance model to help to choose
Scientific computations on modern parallel vector systems
- In Proceedings of the IEEE Conference on Supercomputing
, 2004
"... Computational scientists have seen a frustrating trend of stagnating application performance despite dramatic increases in the claimed peak capability of high performance computing systems. This trend has been widely attributed to the use of superscalar-based commodity components who’s architectural ..."
