Torsten Hoefler:
| | | Performance Modeling for Systematic Performance Tuning
(Presentation - presented in Aachen, Germany, Mar. 2012)
AbstractThe performance of parallel scientific applications depends
on many factors which are determined by the execution en-
vironment and the parallel application. Especially on large
parallel systems, it is too expensive to explore the solution
space with series of experiments. Deriving analytical models
for applications and platforms allow estimating and extrapolating their execution performance, bottlenecks, and the
potential impact of optimization options. We propose to use
such “performance modeling” techniques beginning from the
application design process throughout the whole software
development cycle and also during the lifetime of supercomputer systems. Such models help to guide supercomputer
system design and re-engineering efforts to adopt applications to changing platforms and allow users to estimate costs
to solve a particular problem. Models can often be built
with the help of well-known performance profiling tools. We
discuss how we successfully used modeling throughout the
proposal, initial testing, and beginning deployment phase of
the Blue Waters supercomputer system.
