The Program Committee for the 2nd USENIX Workshop on Hot Topics in Parallelism (HotPar '10) invites you to submit position papers. HotPar '10 will bring together researchers and practitioners doing innovative work in the area of parallel computing. HotPar recognizes the broad impact of multicore computing and seeks relevant contributions in all fields, including application design, languages and compilers, systems, and architecture. We request submissions of position papers that propose new directions for research of products in these areas, advocate non-traditional approaches to the problems engendered by parallelism, or potentially generate controversy and discussion. Submissions are due January 24, 2010. More information and submission guidelines are available at http://www.usenix.org/hotpar10/cfpa We look forward to receiving your submissions! Sincerely, Geoff Lowney, Intel David Patterson, University of California, Berkeley HotPar '10 Program Co-Chairs hotpar10chairs@usenix.org
