Colloquium - Messmer

ECCR 265

Challenges Faced on Petascale Architectures
Peter Messmer
Tech-X Corporation

Petascale systems, consisting of tens or even hundreds of thousands of processors, have the potential to advance numerical simulations to the next level. However, in order to fully take advantage of these systems, applications have to be carefully optimized. Interprocessor communication, deep memory hierarchies and complex control flows require code tuning at different levels. Especially with the advent of heterogeneous architectures, consisting of CPUs supplemented with GPUs, Cells, FPGAs or other highly specialized processing elements, code optimization has become even more important, but at the same time also more difficult. In this talk, we will introduce some of the tools and general strategies used for code tuning on such systems and share some experiences from dealing with real-world codes.

Hosted by Elizabeth Jessup.

The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
