TAU Performance System

Abstract

The TAU Performance System 1 is a versatile performance evaluation tool that supports OpenCL, DPC++/SYCL, OpenMP, and other GPU runtimes. It features a performance profiling and tracing module that is widely portable and can access hardware performance counter data at the GPU and CPU level. This talk will describe the usage and new features of TAU for performance evaluation of HPC and AI/ML workloads. TAU is integrated in the Extreme-Scale Scientific Software Stack (E4S) 2 and is available in containerized and cloud environments. The talk/tutorial will demonstrate the usage of TAU on uninstrumented applications.
