Profiling HPC codes with TAU

SESSION: BE Session IVA: Programming for Exascale - Advanced Sessions

EVENT TYPE: HPC Interconnections (BE, Undergraduates, Cluster)

TIME: 10:30AM - 11:00AM

SESSION CHAIR: Karla Morris

Presenter(s):Sameer S. Shende

ROOM:288-89

ABSTRACT:

The TAU Performance System helps computational scientists evaluate the performance of their codes. This talk will highlight the features of the toolkit and show how its profiling and debugging capabilities can be applied to isolate performance and memory bugs. The talk will introduce basic profiling and performance tuning concepts and will show new techniques that include
event-based sampling, rewriting binaries, runtime preloading, OpenMP instrumentation using OMPT tools interface, and source based instrumentation.

TAU supports both profiling and tracing modes of measurement. This talk will highlight TAU's use for a wide variety of languages and runtime systems, including MPI, CUDA, pthread, OpenMP and OpenACC.
