at the distributed virtual Program Committee meeting. Each paper's review recomm- dationswere carefully checkedfor consistency; in many instances, the Vice Chairs read the papers themselves when the reviews did not seem suf?cient to make a decision. Throughout the reviewing process, I received a tremendous amount of help and advice from General Co-chair Manish Parashar, Steering Chair Viktor Prasanna, and last year's Program Chair Srinivas Aluru; I am very grateful to them. My thanks also go to the Publications Chair Sushil Prasad for his outstanding efforts in putting the proceedings together. Finally, I thank all the authors for their contributions to a hi- quality technical program. I wish all the attendees a very enjoyable and informative meeting. December 2008 P. Sadayappan Message from the General Co-chairs and the Vice General Co-chairs On behalf of the organizers of the 15th International Conference on High-Performance Computing(HiPC), it is our pleasureto present these proceedingsand we hopeyou will ?nd them exciting and rewarding. TheHiPCcallforpapers, onceagain, receivedanoverwhelmingresponse, attracting 317submissionsfrom27countries.P.Sadayappan, theProgramChair, andthe Program Committee worked with remarkablededication to put together an outstandingtechnical program consisting of the 46 papers that appear in these proceedings.

This book constitutes the thoroughly refereed post-proceedings of the 18th International Workshop on Languages and Compilers for Parallel Computing, LCPC 2005, held in Hawthorne, NY, USA in October 2005.

The 26 revised full papers and 8 short papers presented were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on register optimization, compiling for FPGA's and network processors, model-driven and empirical optimization, parallel languages, speculative execution, run-time environments, high-productivity languages for HPC: compiler challenges, and compile-time analysis.

This book constitutes the thoroughly refereed post-workshop proceedings of the 10th International Workshop on Languages and Compilers for Parallel Computing, LCPC'97, held in Minneapolis, Minnesota, USA in August 1997
The book presents 28 revised full papers together with four posters; all papers were carefully selected for presentation at the workshop and went through a thorough reviewing and revision phase afterwards. The papers are organized in topical sections on data locality, program analysis, automatic parallelization, HPF extensions and compilers, synchronization and communication, parallel programming models and language extensions, and instruction level parallelism.
