Tutorial on Automatic Performance and Energy Tuning with the Periscope Tuning Framework

SESSION: Tutorial on Automatic Performance and Energy Tuning with the Periscope Tuning Framework

EVENT TYPE: Tutorials

EVENT TAG(S): Energy, Power, Reconfigurable Computing, Accelerators, Performance

TIME: 8:30AM - 12:00PM

Presenter(s):Michael Gerndt, Renato Miceli

ROOM:19A

ABSTRACT:

A new era in performance engineering of HPC applications is upcoming where traditional manual tuning methods will be challenged by complex performance interactions, dynamic runtime execution, multi-objective optimizations and the never-ending evolution of hardware architectures. A promising strategy is to apply auto-tuning methodologies enhanced by performance analysis capabilities, sophisticated search techniques and code generation methods.

The AutoTune consortium and its partners propose a half-day tutorial on parallel application performance and energy-efficiency auto-tuning, featuring the Periscope Tuning Framework (PTF), an open-source extensible framework for automatic optimization of HPC applications. The tutorial builds on a long track of tutorials on automatic performance analysis and tuning at conferences such as ISC, EuroMPI, CGO as well as on a series of end-user training workshops.

The target audience are HPC application developers striving for higher performance of their applications as well as performance tool developers seeking for comprehensive tool infrastructures. Based on case studies with real-world applications participants will be empowered to utilize PTF to achieve gains in performance and energy-efficiency for their applications. In the second half we will walk through on how to write your own auto-tuning plugin for PTF enabling tool developers and advanced users to quickly prototype tailored auto-tuners.
