The ACM International Conference on Supercomputing serves as the leading international forum for presenting research results in high-performance computing systems. The 40th edition of ICS will be held in Belfast, Northern Ireland (United Kingdom) from July 6th-9th, 2026. ICS 2026 holds two cycles of paper submissions.
Papers are solicited on all aspects of the architecture, software, and applications of high-performance computing systems of all scales (from chips to supercomputing systems), including but not limited to:
Papers will be evaluated based on their novelty, technical soundness, and potential impact on the field. The review process includes a rebuttal phase, and the committee’s discussions will take the authors’ responses into account. A paper cannot be submitted to both cycles.
Accepted papers will be published in the ACM proceedings. Have in mind that ACM’s publications policies apply to all submitted papers, including ACM’s new Publications Policy on Research Involving Human Participants and Subjects. 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.
Starting January 1, 2026, ACM will fully transition to Open Access. All ACM publications, including those from ACM-sponsored conferences, will be 100% Open Access. Authors will have two primary options for publishing Open Access articles with ACM: the ACM Open institutional model or by paying Article Processing Charges (APCs). With over 1,800 institutions already part of ACM Open, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 70-75%).
Authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a financial or discretionary waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the APC Waivers and Discounts Policy. Keep in mind that waivers are rare and are granted based on specific criteria set by ACM.
Understanding that this change could present financial challenges, ACM has approved a temporary subsidy for 2026 to ease the transition and allow more time for institutions to join ACM Open. The subsidy will offer:
This represents a 65% discount, funded directly by ACM. Authors are encouraged to help advocate for their institutions to join ACM Open during this transition period.
This temporary subsidized pricing will apply to all conferences scheduled for 2026.
In the case of authors who may require visas to enter the UK to attend the conference, we encourage them to apply for them early (e.g., at submission time). Please, have in mind that in the unfortunate event that authors do not receive visas on time for the conference, they will be required to provide a proof of the pending or rejected visa application. Please see the ICS website TBA for details.
