*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title
AM++: A Generalized Active Message Framework
Abstract
Active messages have been shown to be a good model to express irregular applications for distributed-memory systems. However, current active messaging frameworks are either too inflexible or too inefficient for use by graph algorithms. We have developed a new framework, AM++, for "generalized active messages" that provides both efficiency and flexibility. It also provides features such as flexible, user-configurable message coalescing and duplicate message elimination without users needing to entangle those behaviors into their applications. Implementation and benchmarking of graph algorithms using AM++ shows the usability benefits of the new features. I will also briefly discuss my work on the Graph 500 benchmark: the graph generators, MPI reference implementations, and the Argonne entry to the first Graph 500 list.
Bio
Jeremiah Willcock is a postdoctoral researcher in the Open Systems Lab at Indiana University. He received his Ph.D. from Indiana University in the area of generic compiler optimizations, then was a postdoctoral researcher in the ROSE project at Lawrence Livermore National Laboratory, in the area of program analysis. His current research interests include abstractions for high-performance and parallel computing, especially in the area of graph algorithms, and programming language features for generic programming.
