Since 1986, LCPC has became a valuable venueforresearchersto reportonworkinthegeneralareaofparallelcomputing, high-performance computer architecture and compilers. LCPC 2009 continued this tradition and in particular extended the area of interest to new parallel computing accelerators such as the IBM Cell Processor and Graphic Processing Unit (GPU). This year we received 52 submissions from 15 countries.

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 c- puter systems.ParalleX,anexploratoryexecutionmodeldevelopedbySterling’s group was introduced to guide the co-design of new architectures, programming methods and system software.

This book constitutes the thoroughly refereed post-workshop proceedings of the 22nd International Workshop on Languages and Compilers for Parallel Computing, LCPC 2009, held in Newark, DE, USA, in October 2009. The 25 revised full papers and 5 revised short papers presented were carefully reviewed and selected from 52 submissions. The papers address all aspects of languages, compiler techniques, run-time environments, and compiler-related performance evaluation for parallel and high-performance computing and extend the area of interest to new parallel computing accelerators such as IBM Cell processor and Graphic Processing Unit (GPU) presenting the latest work of leading researchers and practitioners in the field
