Performance Evaluation Using the TAU Performance System

SESSION: Fortran 2008 Coarrays and Performance Analysis

EVENT TYPE: HPC Interconnections, Broader Engagement

TIME: 11:00AM - 11:30AM

SESSION CHAIR: Fernanda Foertter

Presenter(s):Sameer Shende

ROOM:705/707/709/711

ABSTRACT:
To meet the needs of computational scientists to evaluate and improve the performance of their parallel, scientific applications, we present the TAU Performance System. This talk will describe a versatile tool for performance profiling, tracing, and debugging I/O and memory issues. This talk will describe some interesting problems in performance evaluation of HPC applications. The talk will introduce profiling and debugging support in TAU. TAU now includes support for tracking callstacks at the point of program failure to isolate runtime faults. The talk will briefly cover performance evaluation of parallel programs written in Python, Fortran, C++, C, and UPC, using MPI, and other runtime layers such as CUDA, C++OpenCL, SHMEM, and OpenMP using the TAU Performance System. We will demonstrate the different techniques for program instrumentation. The talk will include support for memory, and I/O evaluation.
