Proceedings of the 1st ACM SIGOPS/EuroSys European Conference on Computer Systems 2006

This is the first Eurosys conference, the first of hopefully many to come. The Eurosys organization grew out of a desire to create a community of systems researchers in Europe. The Eurosys conference is its flagship event. While held in Europe, Eurosys is not meant to be a European conference in the sense that it caters principally to European authors. The composition of the program committee of Eurosys 2006 reflects this international stance: 7 members come from Europe, 7 from the United States, 1 from India, and 1 from Israel.The conference tried to break new ground in several ways. The call for papers covered a very wide range of topics. To further foster diversity in the program, authors were limited to submitting at most two papers. Papers presenting new ideas and experience papers were encouraged, and separate sessions were set aside for those papers. Starting a new conference is always a risky proposition, but the results speak for themselves. The community responded in large numbers, and the program committee was able to put together a high-quality program.We received 174 abstracts, of which 144 turned into paper submissions. We followed a two-round reviewing process, now common in many conferences. In the first round we obtained three reviews for each paper. On the basis of these reviews 69 papers were selected to go forward to the second round, during which we collected 2 or 3 more reviews on each paper. The program committee met on January 6, 2006, in Lausanne, Switzerland, for a full-day meeting. All papers that made it to the second round were discussed during the meeting. 29 selected papers are included in the proceedings. In all, each program committee member, assisted by external reviewers, wrote about 40 reviews, for a total of 639 reviews.
