MoreVMs'20: Workshop on Modern Language Runtimes, Ecosystems, and VMs
Update: MoreVMs’20 goes virtual!
Due to ‹Programming› 2020 not being held as planned (see Health Information), MoreVMs’20 will be a virtual workshop for the first time. Our invited speakers from Red Hat and Google as well as most contributors have agreed to participate and to give their talks online. The virtual workshop is planned for Apr 8, 9:30am to 1pm CEST. The link to the call is below (see Zoom Meeting). We expect the event to be hosted on Zoom, in case you’d like to familiarize yourself with it. Please reach out to the organizing committee if you have any questions. We look forward to the presentations and fruitful discussions!
The virtual workshop is unfortunately over. Recordings of all talks are available on YouTube.

Following three previous successful editions, the MoreVMs’20 workshop aims to bring together industrial and academic programmers to discuss the design, implementation, and usage of modern languages and runtimes. This includes aspects such as reuse of language runtimes, modular implementation, language design and compilation strategies. By bringing together both researchers and practitioners, the workshop aims to enable a diverse discussion on how languages and runtimes are currently being utilized, and where they need to improve further.

Accepted Papers and Talks
Call for Extended Abstracts and Talks
Following three previous successful editions, the MoreVMs’20 workshop aims to bring together industrial and academic programmers to discuss the design, implementation, and usage of modern languages and runtimes. This includes aspects such as reuse of language runtimes, modular implementation, language design, and compilation strategies. By bringing together both researchers and practitioners, the workshop aims to enable a diverse discussion on how languages and runtimes are currently being utilized, and where they need to improve further.
In addition to conventional workshop-style submissions, MoreVMs also accepts (and encourages) submissions that present early-stage work and emerging ideas.
Relevant topics include, but are definitely not limited to, the following:
- Extensible VM design (compiler- or interpreter-based VMs)
- Reusable components (e.g. interpreters, garbage collectors, …)
- Static and dynamic compilation techniques
- Interoperability between languages
- Tooling support (e.g. debugging, profiling, etc.)
- Programming language development environments
- Case studies of existing language implementation approaches
- Language implementation challenges and trade-offs
- Surveys and usage reports to understand usage in the wild
- Ideas for more predictable performance
- Ideas for how VMs could take advantage of new hardware features
- Ideas for how we should build languages in the future
Workshop Format and Submissions
We welcome presentation proposals in the form of extended abstracts (2 to 4 pages long) and talk proposals (title and 400 words abstract) discussing new techniques, insights, experiences, works-in-progress, as well as future visions, from either an academic or industrial perspective.
The extended abstracts and talk proposals, and if the speakers wish, their slides, will be published on the workshop’s website. Alternatively, extended abstracts can be published as part of the companion of ‹Programming›’20 in the ACM DL. Publication in the ACM DL is conditional on the acceptance by the program committee.
Please note that MoreVMs’20 is organized as an academic workshop, and as such, speakers will be required to register for the workshop. We regret that we are unable to cover registration, travel, or accommodation costs for authors.
Submissions should use the ACM
If you are using LaTeX, submissions should use the ‘acmart’ document class with the ‘sigconf’ option, and with a font size of 9 point. Please use the Libertine/Biolinum font family. Please include page numbers in your submission using the LaTeX command
All submissions should be in PDF format.
Please also ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes are legible.
Please refer to the side-bar.
