The SC07 Technical Papers program is the premier forum for disseminating innovative and important advances in high-performance computing, networking, and storage from academic, government, and corporate institutions around the world. Fifty-four papers have been selected for presentation in Reno from 268 submissions contributed by 257 authors. The Technical Papers program spans theory, practice, modeling, experimentation, infrastructure, and application of high performance computing, advanced networking, innovative storage solutions, systems engineering and grid technologies. The papers are presented in 18 sessions over three days.

Awards are given for best technical paper and best student paper. In all, 5 papers are candidates for Best Paper and 5 are candidates for Best Student Paper. The nominated papers are marked within the program and the winning submissions will be announced during the conference awards ceremony on Thursday afternoon at 1:30PM.

The Technical Papers program is the culmination of hundreds of thousands of hours of individual and group efforts. Special thanks to the Technical Papers Committee and the 121 external referees, listed. The quality of the program is a testament to their tireless efforts and commitment to the paper review process. The review process had a new twist this year in that it was done in a double blind fashion; reviewers did not know the authors of each submission they reviewed. The Area Chairs deserve special note, as the process would not have worked without them. Thanks, too, to the SC07 Technical Program Committee and other conference committees that support the technical papers program in myriad ways. Finally, we thank the authors for contributing to an exceptional program. We welcome your participation in the SC07 Technical Papers program.
