It is our pleasure to introduce Volume II of ASPLOS ’23. For the first time, ASPLOS has embarked on a new multi-deadline review model. ASPLOS ’23 features 3 deadlines spaced throughout the year and papers will be published in three volumes. Multiple deadlines are meant to encourage authors to submit their papers when ready and to facilitate the selection of some papers for revision. For this volume of ASPLOS ’23, we discontinued the use of the 2-page extended abstract submissions that were used in ASPLOS ’21 and ASPLOS ’22. We found the extended abstract offered limited filtering and moved to a more traditional two phase review process. Each paper received 3 reviews in phase 1 and papers with positive scores advanced to the second round and received up to 2 more reviews. In our preface to Volume III, we will give a more detailed rundown of how the process worked.
