Streamline Integration Using MPI-Hybrid parallelism on a Large Multicore Architecture
收藏 引用
IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS 2011年 第11期17卷 1702-1713页
作者: Camp, David Garth, Christoph Childs, Hank Pugmire, Dave Joy, Kenneth I. Univ Calif Davis Lawrence Berkeley Natl Lab Davis CA 95616 USA Univ Calif Davis Dept Comp Sci Davis CA 95616 USA Oak Ridge Natl Lab Oak Ridge TN 37831 USA
Streamline computation in a very large vector field data set represents a significant challenge due to the nonlocal and data-dependent nature of streamline integration. In this paper, we conduct a study of the perform... 详细信息

Prediction of Optimal parallelism Level in Wide Area Data Transfers
收藏 引用
IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS 2011年 第12期22卷 2033-2045页
作者: Yildirim, Esma Yin, Dengpan Kosar, Tevfik SUNY Buffalo Dept Comp Sci & Engn Buffalo NY 14260 USA Louisiana State Univ Dept Comp Sci Baton Rouge LA 70803 USA Louisiana State Univ Ctr Computat & Technol Baton Rouge LA 70803 USA
Wide area data transfer may be a major bottleneck for the end-to-end performance of distributed applications. A practical way of increasing the wide area throughput at the application layer is using multiple parallel ... 详细信息

An OpenMP Extension that Supports Thread-Level Speculation
收藏 引用
IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS 2016年 第1期27卷 78-91页
作者: Aldea, Sergio Estebanez, Alvaro Llanos, Diego R. Gonzalez-Escribano, Arturo Univ Valladolid Dept Informat Campus Miguel Delibes E-47011 Valladolid Spain
OpenMP directives are the de-facto standard for shared-memory parallel programming. However, OpenMP does not guarantee the correctness of the parallel execution of a given loop if runtime data dependences arise. Conse... 详细信息
