Performance Analysis and Optimal Node-Aware Communication for Enlarged Conjugate Gradient Methods
Shelby Lockhart, Amanda Bienz, William Gropp +1
Krylov methods are a key way of solving large sparse linear systems of equations, but suffer from poor strong scalabilty on distributed memory machines. This is due to high synchro…
Exploring Spatial Indexing for Accelerated Feature Retrieval in HPC
Margaret Lawson, William Gropp, Jay Lofstead
Despite the critical role that range queries play in analysis and visualization for HPC applications, there has been no comprehensive analysis of indices that are designed to accel…
Optimizing Noncontiguous Accesses in MPI-IO
Rajeev Thakur, William Gropp, Ewing Lusk
The I/O access patterns of many parallel applications consist of accesses to a large number of small, noncontiguous pieces of data. If an application's I/O needs are met by making…
Learning from the Success of MPI
William D. Gropp
The Message Passing Interface (MPI) has been extremely successful as a portable way to program high-performance parallel computers. This success has occurred in spite of the view o…
Components and Interfaces of a Process Management System for Parallel Programs
Ralph Butler, William Gropp, Ewing Lusk
Parallel jobs are different from sequential jobs and require a different type of process management. We present here a process management system for parallel programs such as those…
