Following four previous successful editions, the MoreVMs’21 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.

                       5th International Workshop on
               Modern Language Runtimes, Ecosystems, and VMs

                     Co-located with ‹Programming›’21
             March 22nd to 26th, 2021, Online, United Kingdom

============================================================================

Following four previous successful editions, the MoreVMs’21 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
 - Techniques for targeting high-level languages such as JavaScript
 - 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›’21 in the
ACM DL. Publication in the ACM DL is conditional on the acceptance by the
program committee.

Please note that MoreVMs’21 is organized as an academic workshop, and as such,
speakers will be required to register for the workshop.

Author Instructions
-------------------

Submissions should use the ACM `acmart` format:
https://www.acm.org/publications/proceedings-template

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 `\settopmatter{printfolios=true}`.

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.
