Insightful Automatic Performance Modeling

SESSION: Insightful Automatic Performance Modeling

EVENT TYPE: Tutorials

EVENT TAG(S): Power

TIME: 1:30PM - 5:00PM

Presenter(s):Alexandru Calotoiu, Felix Wolf, Torsten Hoefler, Martin Schulz

ROOM:18A

ABSTRACT:

Many applications suffer from latent performance limitations that
may cause them to consume too many resources under certain
conditions. Examples include the input-dependent growth of the
execution time. Solving this problem requires the ability to
properly model the performance of a program to understand its
optimization potential in different scenarios. In this tutorial, we
will present a method to automatically generate such models for
individual parts of a program from a small set of
measurements. We will further introduce a tool that implements our
method and teach how to use it in practice. The learning objective
of this tutorial is to familiarize the attendees with the ideas
behind our modeling approach and to enable them to repeat
experiments at home.
