Copyright Notice : It is understood that the following electronic versions of the papers are non-commercial, pre-print versions available to ensure the timely dissemination of their content. Copyrights for each published paper are held by the respective publishing organization.

In the field of experimental computer systems research, publications in top conferences tend to have higher impact, visibility and recognition than publications in top journals. Top conferences conduct extremely rigorous review processes, involving 3 to 7 reviewers, multiple rounds of reviews with author rebuttal, a face-to-face, panel-style, consensus-based program committee meeting of leading experts who select the accepted papers, and shepherding of the accepted papers. Top conferences also have competitive acceptance rates, often not higher than 20%, which is lower than most journals. This practice reflects the culture of the field and may change in the future. For more details, please consult the related CRA Best Practices Memo.
