PPOPP

It is our great pleasure to welcome you to the 17th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming (PPoPP'12). PPoPP continues its tradition of serving as a leading forum for research in all aspects of parallel software, including theoretical foundations, programming models, algorithms, applications, and systems software. With the ubiquity of parallelism in commodity processors and the increasing use of GPUs for high-performance computing, the effective use of parallel systems is being recognized as one of the most challenging problems faced today.

PPoPP'12 received 173 complete paper submissions. In addition to the 25 program committee members, 75 members of the external review committee provided reviews for the papers. Two rounds of reviewing were conducted, with at least three reviews being obtained in the first round, with additional reviews being obtained in the second round for papers where needed. After extensive discussions at an in-person two-day program committee meeting in November 2011, 26 full papers were selected for presentation at the conference. PPoPP'12 continues the tradition of poster presentations of high quality submissions that could not be accepted as full papers. This year's conference features 32 poster presentations over two sessions.

PPoPP'12 is again co-located this year with the International Symposium on High-Performance Computer Architecture (HPCA), allowing attendees of one conference the option of attending talks at the other. We feature two joint HPCA/PPOPP keynote presentations. Sanjeev Kumar from Facebook will present a keynote on "Social Networking at Scale," and Keshav Pingali from the University of Texas at Austin will present a keynote entitled "Parallel Programming Needs Data-Centric Foundations."
