22nd International Workshop, LCPC 2009, Newark, DE, USA, October 8-10, 2009. Revised Selected Papers. — Springer Science & Business Media, 2010. — 426 p. — (Lecture Notes in Computer Science 5898).This year we received 52 submissions from 15 countries. Each submission receivedatleastthreereviewsandmosthadfour.ThePCalsosoughtadditional external reviews for contentious papers. The PCheldanall-dayphone conference on August 24 to discuss the papers. PC members who had a conflict of interest were asked to leave the call temporarily when the corresponding papers were discussed. From the 52 submissions, the PC selected 25 full papers and 5 short papers to be included in the workshop proceeding, representing a 58% acceptance rate. We were fortunate to have three keynote speeches, a panel discussion and a tutorial in this year’s workshop. First, Thomas Sterling, Professor of Computer Science at Louisiana State University, gave a keynote talk titled “HPC in Phase Change: Towards a New Parallel Execution Model.” Sterling argued that a new multi-dimensional research thrust was required to realize the design goals with regard to power, complexity, clock rate and reliability in the new parallel computer systems. ParalleX, an exploratory execution model developed by Sterling’s group was introduced to guide the co-design of new architectures, programming methods and system software.
