POMACS V9, N1, March 2025 Editorial

The Proceedings of the ACM on Measurement and Analysis of Computing Systems (POMACS) focuses on the measurement and performance evaluation of computer systems and operates in close collaboration with the ACM Special Interest Group SIGMETRICS. All papers in this issue of POMACS will be presented at the ACM SIGMETRICS 2025 conference on June 9-13, 2025, in Stony Brook, New York, USA. The papers in this issue were selected during the fall submission round by the 94 members of the ACM SIGMETRICS 2025 program committee via a rigorous review process. Each paper was conditionally accepted (and shepherded), or allowed to be resubmitted to one of the subsequent two SIGMETRICS deadlines, or rejected (with resubmission allowed only after a year). POMACS is publishing 14 papers out of 113 submissions in this issue, of which 2 had previously received a resubmit decision. One accepted paper opted out of publication in POMACS. Submissions typically receive at least three reviews. While most papers were decided in the online discussion phase, borderline cases were extensively discussed during the online program committee meeting. Based on the indicated track(s), roughly 25% of the submissions were in the Theory track, 25% were in the Measurement & Applied Modeling track, 31% were in the Systems track, and 19% were in the Learning track. Many individuals contributed to the success of this issue of POMACS. We would like to thank the authors, who submitted their best work to SIGMETRICS/POMACS. We would also like to thank the program committee members who provided constructive feedback in their reviews to authors and participated in the online discussions and program committee meeting. Further, we thank the several external reviewers who provided their expert opinions on specific submissions that required additional input. Finally, we are also grateful to the ACM SIGMETRICS Chair, Mor Harchol-Balter, to the SIGMETRICS Organization Committee and to the SIGMETRICS Executive Committee for their ongoing efforts and initiatives for creating an exciting program for ACM SIGMETRICS 2025. We hope that you enjoy reading the papers in this POMACS issue, and we look forward to your continued submissions to the ACM SIGMETRICS conference and the POMACS journal.
