Multicore Programming Challengeslticore” technology by designing processors that have multiple processing cores on each silicon chip. Increasing the number of cores per chip has enable processor peak performance to double with each doubling of the number of cores. With performance doubling occurring at approximately constant clock

What Is in a Namespace?ht how a namespace can be used and the differences between algorithms designed to work in virtual versus physical topologies..In the second half of the talk I will then outline how recently we have begun more deeply exploring the relationship between physical and virtual topologies. The first is exp

A Holistic Approach towards Automated Performance Analysis and Tuningnd thus be reused in the future. We demonstrate the effectiveness of our approach through the automated performance analysis and tuning of two scientific applications. We show that the tuning process is highly automated, and the performance improvement is significant.

Grouping MPI Processes for Partial Checkpoint and Co-migrationfrequently, performance will be adversely affected..To address this problem, we present an approach to identify and group processes which we expect to be frequent communicators in the near future. Then, when one or more process is performing poorly, the entire group is checkpointed and co-migrated.
