Journal ArticleDOI
Supporting nested OpenMP parallelism in the TAU performance system
TL;DR: This paper describes the problem and a novel solution for identifying threads uniquely in nested OpenMP applications with nested parallelism and describes how extensions to the OpenMP standard can help tool developers uniquely identify threads.
Book ChapterDOI
Performance Analysis of OpenSHMEM Applications with TAU Commander
John C. Linford,Samuel Khuvis,Sameer Shende,Allen D. Malony,Neena Imam,Manjunath Gorentla Venkata +5 more
TL;DR: This work compares TAU and TAU Commander workflows for common performance engineering tasks in OpenSHMEM applications and demonstrates workflows targeting two different SHMEM implementations, Intel Xeon “Haswell” and “Knights Landing” processors, direct and indirect measurement methods, callsite, profiles, and traces.
Proceedings ArticleDOI
Performance Visualization for TAU Instrumented Scientific Workflows.
Cong Xie,Wei Xu,Sungsoo Ha,Kevin Huck,Sameer Shende,Hubertus J. J. van Dam,Kerstin Kleese van Dam,Klaus Mueller +7 more
TL;DR: This ongoing work presents a web-based visualization framework, whose back end handles data storage, query and aggregation, while front end presents the visualization and takes user interaction, and aims to solve two current challenges: the capability to deal with workflows, and the scalability toward exascale scenario.
Journal ArticleDOI
Performance analysis of GYRO: a tool evaluation
Patrick H. Worley,Jeff Candy,Laura Carrington,Kevin Huck,T Kaiser,G. Mahinthakumar,Allen D. Malony,Shirley Moore,Daniel A. Reed,P. Roth,Hongzhang Shan,Sameer Shende,Allan Snavely,Sarat Sreepathi,Felix Wolf,Yilei Zhang +15 more
TL;DR: The paper briefly discusses what has been discovered via this manual analysis process, what performance analyses are inconvenient or infeasible to attempt manually, and to what extent the tools show promise in accelerating or significantly extending the manual performance analyses.
Journal ArticleDOI
Using coarrays to parallelize legacy fortran applications: strategy and case study
TL;DR: This paper summarizes a strategy for parallelizing a legacy Fortran 77 program using the object-oriented (OO) and coarray features that entered Fortran in the 2003 and 2008 standards and shows linear speedup even in distributed-memory execution.
