*TITLE*: Sustainable Multi-level Tuning for Exascale Science Applications

*TIME*:  3:30 PM

*LOCATION*:  GMCS 314

*SPEAKER*:  Dr. Tony Drummond. Senior Scientist at Global Footprint Network.

*ABSTRACT*:  Enabling performance sustainability for complex parallel
computer applications and high-end simulations requires the coherent
integration of software programming practices and environments, static
tuning and automatic tuning, both on-line and off-line.  The end goal is to
produce code that maximizes the resource utilization, runs at desired
computational scales and produces meaningful results that advance the
science.  Here, we look at a multi-stage software tuning workflow, which
covers from algorithmic implementations to full computational applications
and large-scale simulations.



This talk will summarize some lessons learned from a computational tuning
workbench where we first use tracing and profiling tools to identify key
hotspots in the code, which are later optimized depending on the nature of
their computational intensity and the available hardware.  The next level
up in tuning, is the use of different optimized algorithmic implementations
or functionalities that are available in the form of computational
kernels.  Implementations of these kernels are part of general-purpose
libraries, software tools or other application codes. Lastly, we look
automating the selection of best kernel in a way that it is sustainably
integrated into the application tuning.

*HOST*:  Dr. Jose Castillo.
