IEEE/ACM International Symposium on Code Generation and Optimization (CGOhttps://2025.cgo.org/) Co-located with PPoPPhttps://conf.researchr.org/series/PPoPP, HPCAhttps://hpca-conf.org/2025/ and CChttps://conf.researchr.org/series/CC Las Vegas, USA The International Symposium on Code Generation and Optimization (CGO’25) will be held in Las Vegas, USA. CGO is the premier venue to bring together researchers and practitioners working at the interface of hardware and software on a wide range of optimization and code generation techniques and related issues. The conference spans the spectrum from purely static to fully dynamic approaches, and from pure software-based methods to specific architectural features and support for code generation and optimization. ________________________________ CGO now uses two submissions per year. This follows the model established by other conferences in our field in recent years, such as ASPLOS and OOPSLA. Papers submitted to the first round can either be directly accepted, rejected, or invited to submit a revised version of the paper to the second round. For papers invited to submit a revised version, authors will be given a list of revisions that should be acted on to improve the paper. We will make every effort to ensure that the revised paper is reviewed by the same referees, who will assess whether the revisions are satisfactory. If so, the paper will be accepted. If a paper is rejected, the authors may still submit a revised version in a subsequent round, which will be treated as a new submission. ________________________________ First Submission Deadline * Paper Submission: May 30, 2024 * Author Rebuttal Period: July 9-11, 2024 * Paper Notification: July 22, 2024 Second Submission Deadline * Paper Submission: September 12, 2024 * Author Rebuttal Period: October 22 - 24, 2024 * Paper Notification: November 4, 2024 Contacts: * Hugh Leather - Meta – hleather@meta.commailto:hleather@meta.com * P.

Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper. ACM has been involved in ORCID from the start and we have recently made a commitment to collect ORCID IDs from all of our published authorshttps://authors.acm.org/author-resources/orcid-faqs. We are committed to improve author discoverability, ensure proper attribution and contribute to ongoing community efforts around name normalization; your ORCID ID will help in these efforts. By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policieshttps://www.acm.org/publications/policies, including ACM's new Publications Policy on Research Involving Human Participants and Subjectshttps://www.acm.org/publications/policies/research-involving-human-participa.... Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy. ________________________________ Call for Tool and Practical Experience Papers CGO has a second category of papers called “Tools and Practical Experience”. Papers in this category must either give a clear account of a tool’s functionality or summarize a practical experience with realistic case studies. The successful evaluation of an artifact is mandatory for a Tool Paper. Therefore, authors of work conditionally accepted as Tool Papers must submit an artifact to the Artifact Evaluation Committee. The successful evaluation of the artifact is a requirement for final acceptance. Practical experience papers are encouraged, but not required, to submit an artifact to the Artifact Evaluation process. The selection criteria for papers in this category are: * Originality: Papers should present CGO-related technologies applied to real-world problems with scope or characteristics that set them apart from previous solutions. * Usability: The presented Tools or compilers should have broad usage or applicability. They are expected to assist in CGO-related research, or could be extended to investigate or demonstrate new technologies. If significant components are not yet implemented, the paper will not be considered. * Documentation: The tool or compiler should be presented on a web-site giving documentation and further information about the tool. * Benchmark Repository: A suite of benchmarks for testing should be provided. * Availability: The tool or compiler should be available for public use. * Foundations: Papers should incorporate the principles underpinning Code Generation and Optimization (CGO). However, a thorough discussion of theoretical foundations is not required; a summary of such should suffice. * Artifact Evaluation: The submitted artifact must be functional and support the claims made in the paper. Submission of an artifact is mandatory for papers presenting a tool. Tool and Practical Experience papers abide by the same limit of 11 pages in the ACM formathttps://www.acm.org/publications/proceedings-template, references excluded, and are not distinguished in the final proceedings. We encourage shorter submissions that give account of how scientific ideas have been incorporated and used in practice. ________________________________ Geographic Diversity and Inclusion Authors of papers accepted for CGO 2025 are encouraged to present their work in person. However, to foster the participation of students and professionals from everywhere, CGO 2025 will allow the remote presentation of papers, if their authors are unable to travel to the conference venue for reasons beyond their control (e.g. visa issues). Additionally, the conference organization will try to make attendance of CGO 2025 affordable for as many people as possible, with a specific focus on students from universities located in under-represented countries who are paper authors. ________________________________ Artifact Evaluation The Artifact Evaluation process is run by a separate committee whose task is to assess how the artifacts support the work described in the papers. This process contributes to improved reproducibility in research that should be a great concern to all of us. There is also some evidence that papers with a supporting artifact receive higher citations than papers without artifact evaluation. Authors of accepted papers at CGO have the option of submitting their artifacts for evaluation within two weeks of paper acceptance. To ease the organization of the AE committee, we kindly ask authors to indicate at the time they submit the paper, whether they are interested in submitting an artifact. Papers that go through the Artifact Evaluation process successfully will receive a seal of approval printed on the papers themselves. Additional information is available on the CGO AE web page. Authors of accepted papers are encouraged, but not required, to make these materials publicly available upon publication of the proceedings. ________________________________ Authors should carefully consider the difference in focus between the co-located conferences when deciding where to submit a paper. CGO will make the proceedings freely available via the IEEE Xplore platform during the period from two weeks before to two weeks after the conference. This option will facilitate easy access to the proceedings by conference attendees, and it will also enable the community at large to experience the excitement of learning about the latest developments being presented in the period surrounding the event itself. ________________________________ Distinguished Paper Awards Up to 10% of papers accepted at CGO 2025 will be designated as Distinguished Papers, following the ACM policy. This award is open to both regular and tool papers.
