xSIG 2026
xSIG (cross-disciplinary workshop on computing Systems, Infrastructures, and programminG) is a workshop from 2017, inheriting the tradition of JSPP，SACSIS，and ACSI. It solicits contributions from a wide range of fields related to computing systems, infrastructures, and programming, spanning all areas covered by the sponsoring special interest groups (cross-SIG).
The main objectives of xSIG are to provide a forum to present and discuss research ideas among researchers spanning many fields and to raise young researchers through a globally standard peer review process. In particular,
-
We hope authors of xSIG workshop to advance their research based on feedback received and step up to submitting their work to international conferences and journals. We do not publish workshop proceedings. The papers presented in xSIG will be available only to the audience during the workshop. For those who want to publish their work, we collaborate with IPSJ Transactions on ACS for Special Issue on xSIG.
-
We hope to give authors substantial feedback as well as a place for young researchers to practice/improve writing papers for review, through the globally standard conference format of submitting papers for review, receiving/writing reviews, discussing papers in the program committee meeting, etc. For this, we establish Young Program Committee alongside the regular Program Committee and welcome the participation of young researchers including students to it, for “an early exposure” of motivated students to peer review work normally done by senior researchers.
-
We award many students.
From 2020, xSIG is co-located with SWoPP event (Summer United Workshops on Parallel, Distributed and Cooperative Processing), in which many SIGs on computing systems held workshops.

About the fees of xSIG
Until xSIG 2024, we have operated the xSIG using the surplus funds of its predecessor, SACSIS. However, since the surplus has been almost completely used up, we would like to ask sponsors and accepted authors to gradually cover the costs of the xSIG. We plan to require payment of 9,900 yen per accepted oral presentation via IPSJ My Page. We would appreciate your cooperation in ensuring the continued implementation of the xSIG.

Call for Papers
Scope and Review Criteria
xSIG solicits contributions from a wide range of fields related to computing systems, infrastructures, and programming, spanning all areas covered by the sponsoring special interest groups. We welcome not only papers with original proposals or ideas but also papers reporting the results of practical research and development. All submitted papers will be reviewed by the Program Committee (PC) to select accepted papers and awards. Moreover, we purpose the progression of the researches and fostering young researchers through the reviewing process. We expect the reviewers to give not only the evaluation of the paper but also constructive comment to advance the research. We expect the author(s) to advance the research, and submit revised papers to international conferences/journals in the near future. To this end, we evaluate submitted papers from the view point not only of the quality of the paper but also of the potential of the research. The presentation quality is taken into account for the evaluation.
Paper Format
The restriction on the submitted paper is relaxed taking advantage of the characteristics that xSIG does not publish proceedings. See HERE for further details.
Submission System
We use EasyChair for paper submission.
Deadline
- Mar. 10, 2026, 17:00 JST: Paper registration due
- Mar. 17, 2026, 17:00 JST: Paper upload due
Awards
Research Awards
We select one Best Research Award, and up to two Outstanding Research Awards.
IEEE Computer Society Japan Chapter xSIG Young Researcher Award
We also selects one or a few IEEE Computer Society Japan Chapter xSIG Young Researcher Award from the papers of which the first authors are aged 40 and below.
Student Awards
We also selects one Best Undergraduate/Master’s Student Award，and up to two Outstanding Undergraduate/Master’s Student Awards from the papers of which the first authors are undergraduate/master’s course students.
Student Awards for Criteria
We select the following awards from papers where the first author is a student at master’s course or below (at the time of submission), and commend the first author as the recipient.
- Outstanding Effort Award (up to around 3 papers) - Recognizes the time and effort invested in implementation, data acquisition, or other technical contributions to the paper.
- Outstanding Presentation Award (up to around 1 paper) - Recognizes clarity in explaining the paper and the soundness of its logical argument.
- Outstanding English Award (up to around 1 paper) - Recognizes excellent English writing.
Young PC members
It is beneficial for young researchers to have experience of a PC member for their research and writing activity. We invite young researchers including students as Young PC members. A student who have had his/her submitted papers reviewed can be a young PC member. A submitted paper is assigned at most one young PC member along with regular PC members. A young PC member reviews the assigned paper, and participates in the discussion at the PC meeting. The regular PC members assigned to the paper and the PC are responsible for the final decision of paper acceptance. If you are interested in, please contact to the organizers by March 10, 2026 (JST).
Duplicated Submission
If a submitted paper and the following paper submitted by the same author or the same group of the authors as the submitted paper are determined identical by the program committee, the submission is regarded as duplicate, and is rejected:
- a paper under review process
- a paper accepted for reviewed publications with ISBN or ISSN
The identity is determined on the basis of the contents, not of the language, style, format, and so on.
If a submission is revealed to be duplicate after acceptance, the acceptance can be rescinded. However, submissions to international conferences or journals are not prohibited after the notification of acceptance.

Other items than these (e.g., acknowledgment) can be included (within word limits).
Word limit
approximately 4,000 to 8,000 words. No limit for references. This would be 5 to 10 pages in 10pt, twocolumn styles.
On-line distribution manuscript
We will collect before the workshop the manuscripts for on-line distribution during the workshop.
LaTeX
If you use LaTeX, the following example will produce a paper that complies with the xSIG format. Note that modifications might be required depending on your style file.

Bachelor/Master Thesis and Paper to Submit
We welcome papers that serves the base for bachelor/master theses. However, a thesis and a papers to submit are different from the purpose. If you try to submit a paper that serves the base for your thesis, attention should be paid to the following items:
- Do not write “Bachelor/Master Thesis” in the header.
- Include all the authors (including you).
- Do not write the adviser or the date of submission to the university office.
- Pay attention to the recipient and contents of the acknowledgement.
In general, too long manuscripts comparing with their technical contents will be poorly evaluated. Since the potential readers of papers submitted to the workshop are specialists of their research area, we recommend to divide the background section into:
- general background that specialists of that area will know and
- paper-specific background that must be explained even to specialists.
The former should be omitted from the paper to submit. This also helps your thesis be more easy to understand.
