June 1–2, 2023
free and online in a virtual format


Talk/Paper Submissions Due: April 14th
Notification of Acceptance: May 12th
Coding Day Submissions Due: May 19th
Coding Day: June 1st
Workshop Day: June 2nd


CHIUW 2023 is the 10th annual Chapel Implementers and Users Workshop, which serves as a forum where users and developers of the general-purpose Chapel programming language (chapel-lang.org) can meet to report on work being done with Chapel, exchange ideas, and forge new collaborations. Anyone interested in parallel programming and/or Chapel is encouraged to attend CHIUW, from long-term enthusiasts to those simply curious to learn more. This year's CHIUW will be online and there will be no registration fees.


Topics of interest for CHIUW include:

- User experiences writing applications in Chapel
- Improvements to the Chapel language, compiler, and runtime
- Performance or benchmark studies involving Chapel
- Libraries or tools for Chapel programmers
- Comparisons to other parallel programming models
- Uses of Chapel in education
- Related topics likely to be of interest to Chapel enthusiasts
- Hands-on activities for the Coding Day


CHIUW 2023 is an independent, virtual workshop consisting of hands-on exercises and participant-driven sessions (Coding Day, June 1st) and Chapel-related presentations and sessions (Workshop Day, June 2nd). Those interested in submitting papers and Coding Day activities should refer to the Submissions section below.

Other workshop activities will include:

- a keynote talk
- a pre-workshop introduction to Chapel for those new to the language
- a "State of the Chapel Project" talk
- a free-form community discussion on Chapel priorities and next steps

All participants at CHIUW will be expected to follow the Chapel Code of Conduct: https://github.com/chapel-lang/chapel/blob/main/CODE_OF_CONDUCT.md


Submissions to CHIUW 2023 can be made in the following forms:

1. Research papers: 5–8 pages, excluding references
Research papers can describe novel R&D being undertaken by the authors, or an update on ongoing efforts that are of interest to Chapel community. Papers will be evaluated by the program committee using typical standards for academic research papers, including plagiarism (and self-plagiarism). Research papers should be prepared using the ACM conference submission format. We strongly recommend checking that each line is numbered to ease and enrich the review process. Acceptance to CHIUW 2023 does not preclude papers from being published elsewhere, and authors are encouraged to submit their work to other venues.

2. Talk proposals: 1–4 pages, excluding references (if any)
To propose a talk at CHIUW, submit an extended abstract describing what you intend to present. CHIUW talks can preview work that is not yet ready for publication, recap work that the speaker has already published, and/or describe work that is not intended for publication. Talk proposals will be evaluated by the program and steering committees based on their expected level of interest to the CHIUW audience. Talk proposals should be formatted reasonably, where using the same template as the research papers is an option, though not a requirement.

3. Coding Day activities:
The CHIUW Coding Day is an opportunity to engage with an experienced Chapel developer such as a member of Chapel's core team on a hands-on coding task or to gain in-depth experience with some aspects of Chapel. Examples include porting a modest amount of existing code, writing an example distributed parallel program to process files in parallel, or asking questions about Chapel features and example codes.

Please submit your research paper or talk proposal via EasyChair: https://easychair.org/conferences/?conf=chiuw2023. To apply for a Coding Day activity please use this form: https://forms.office.com/r/vUg2kUYa9X.


A single-blind reviewing process will be used for manuscripts. Conflicts of interest (COI) will be observed, such as shared affiliations and previous co-authorships (within the past four years), or advising relationships (at any time). PC members will not review a paper whose authors include someone with whom they have a COI.


Depending on scheduling constraints, each accepted research paper and talk proposal will have 15–25 minutes of presentation time, followed by 5 minutes of Q&A. Research papers that are not accepted for publication at CHIUW 2023 will automatically be considered as a talk proposal submission. If accepted as such, authors can submit a shorter version of their work for the final version. Coding Day participants are strongly encouraged to to give a short summary of their coding day experience during the second day of CHIUW, as an informal talk or virtual poster.

Accepted submissions will be made publicly available through the CHIUW 2023 website.


If you have any questions or suggestions to improve CHIUW, please contact chapel+info at discoursemail.com
