SPAA

This volume consists of papers that were presented at the 24th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA 2012), held on 25-27 June 2012, in Pittsburgh, Pennsylvania, USA. It was sponsored by the ACM Special Interest Groups on Algorithms and Computation Theory (SIGACT) and Computer Architecture (SIGARCH) and organized in cooperation with the European Association for Theoretical Computer Science (EATCS). Financial support was provided by Akamai, IBM Research, and ACM SIGARCH.

The program committee selected the 31 SPAA 2012 regular presentations following electronic discussions. Of these papers, the paper Memory-Mapping Support for Reducer Hyperobjects by ITing Lee, Aamir Shafi, and Charles Leiserson was selected to receive the best paper award.

The regular presentations were selected out of 120 submitted abstracts. The mix of selected papers reflects the unique nature of SPAA in bringing together the theory and practice of parallel computing. SPAA defines parallelism very broadly to encompass any computational device or scheme that can perform multiple operations or tasks simultaneously or concurrently. The technical papers in this volume are to be considered preliminary versions, and authors are generally expected to publish polished and complete versions in archival scientific journals.

In addition to the regular presentations, this volume includes 8 brief announcements. The committee's decisions in accepting brief announcements were based on the perceived interest of these contributions, with the goal that they serve as bases for further significant advances in parallelism in computing. Extended versions of the SPAA brief announcements and posters may be published later in other conferences or journals. Finally, this year's program also included keynote addresses by Ravi Rajwar of Intel Corporation, and Doug Lea of the State University of New York at Oswego.
