The SC12 Technical Papers program received 472 submissions covering a wide variety of research topics in high performance computing. We followed a rigorous peer review process with a newly introduced author rebuttal period, careful management of conflicts, and four reviews per submission (in most cases). At a two-day face-to-face committee meeting on June 25-26 in Salt Lake City, over 100 technical paper committee members discussed every paper and finalized the selections. At the conclusion of the meeting, SC12 Technical Papers had accepted 100 papers, reflecting an acceptance rate of 21 percent. Additionally, 13 of the 100 accepted papers have been selected as finalists for the Best Paper and Best Student Paper awards. Winners will be announced during the SC12 Awards Session on Thursday, November 15, 2012.
