Second Workshop on Irregular Applications: Architectures & Algorithms - IA3 2012

This workshop, this year in its second edition, aims at bringing together scientists with all these different backgrounds to discuss, define and design methods and technologies for efficiently supporting irregular applications on current and future machines. The call for papers attracted 10 submissions from Asia, Europe and the United States. The program committee accepted 6 papers, organized in three sessions: architectures for irregular algorithms, using GPUs for Irregular Applications, and Programming Models for Irregular Applications. The program included two keynote speeches: "Big Data: OPs vs FLOPs" by Steve Wallach and "Irregular Applications and Their Architectural Challenges" by Dr. Pradeep Dubey. Finally, an outstanding panel of speakers (Umit Catalyurek, Pradeep Dubey, David Gleich, Alex Ramirez, Vinod Tipparaju, Steve Wallach) discussing current challenges and possible solutions for the efficient execution of irregular applications concluded the program. We hope that these proceedings will serve as a valuable reference for researchers and developers in the field of irregular applications.
