MPLR 2025

The 22nd International Conference on Managed Programming Languages and Runtimes (MPLR 2025, formerly ManLang, originally PPPJ) is a premier forum for presenting and discussing novel results in all aspects of managed programming languages and runtime systems, which serve as building blocks for some of the most important computing systems around, ranging from small-scale (embedded and real-time systems) to large-scale (cloud-computing and big-data platforms) and anything in between (mobile, IoT, and wearable applications).

Papers accepted by MPLR 2025 describe original research results and have not been published anywhere else. Each submitted paper has received a minimum of three reviews by members of the program committee. Papers have been selected based on their originality, relevance, technical clarity, and quality of presentation. At least one author of each accepted paper must register for the MPLR 2025 symposium and present the paper.

Call for Papers

The 22nd International Conference on Managed Programming Languages & Runtimes (MPLR, formerly ManLang, originally PPPJ) is a premier forum for presenting and discussing novel results in all aspects of managed programming languages and runtime systems, which serve as building blocks for some of the most important computing systems in use, ranging from small-scale (embedded and real-time systems) to large-scale (cloud-computing and big-data platforms) and anything in between (desktop, mobile, IoT, and wearable applications).

Topics

The areas of interest include but are not limited to:

• Languages and Compilers
  • Managed languages (e.g., Java, Scala, JavaScript, Python, Ruby, C#, F#, Clojure, Groovy, Kotlin, R, Smalltalk, Racket, Rust, Go, Lua, MATLAB, Raku, Pony, …)
  • Domain-specific languages
  • Language design
  • Compilers and interpreters
  • Type systems and program logics
  • Language interoperability
  • Parallelism, distribution, and concurrency
• Virtual Machines
  • Portable intermediate representations (e.g., JVM, WebAssembly, RPython, …)
  • Managed runtime systems (e.g., GraalVM, Android Runtime (ART), V8, JavaScriptCore, .NET, …)
  • VM design and optimization
  • VMs for mobile and embedded devices
  • VMs for real-time applications
  • Memory management and garbage collection
  • Hardware/software co-design
  • Persistence
• Techniques, Tools, and Applications
  • Static and dynamic program analysis
  • Testing and debugging
  • Refactoring
  • Program understanding
  • Program synthesis
  • Security and privacy
  • Performance analysis and monitoring
  • Compiler and program verification and model checking

If you are unsure whether a particular topic falls within the scope of MPLR ’25 or if you have any other questions, please do not hesitate to contact the Program Chair Tomoharu Ugawa at ugawa ci i u-tokyo ac jp.

Submission Categories

MPLR accepts three types of submissions:

• Regular research papers, describing novel contributions involving managed language platforms. Research papers will be evaluated based on their relevance, novelty, technical rigor, and contribution to the state-of-the-art. (Format: up to 12 pages, excluding bibliography and appendix);
• Work-in-progress research papers, describing hot topics or promising new ideas, with perhaps less maturity than full papers. Work-in-progress papers will be evaluated with an emphasis on novelty and the potential of the new ideas instead of technical rigor and experimental results. (Format: up to 6 pages, excluding bibliography and appendix);
• Industry and tool papers, presenting technical challenges and solutions for managed language platforms in the context of deployed applications and systems. Industry and tool papers will be evaluated on their relevance, usefulness, and results. Suitability for demonstration and availability will also be considered for tool papers. (Format: up to 6 pages, excluding bibliography and appendix; up to 12 pages allowed if justified by the content);

Accepted submissions will be published in the ACM Digital Library, except if the authors prefer not to be included.

MPLR 2025 submissions must conform to the ACM Policy on Prior Publication and Simultaneous Submissions and to the SIGPLAN Republication Policy. See http://www.sigplan.org/Resources/Policies/Republication

MPLR 2025 will not hold its own poster session. Please consider submitting to the SPLASH poster track.

Author Instructions

Submissions need to use the ACM SIGPLAN format with the sigplan style.

If you are using LaTeX, submissions need to use the acmart document class with the sigplan option (not the sigconf option). In the acmart-primary.zip file that downloads from the LaTeX (Version 1.90) link on the https://www.acm.org/publications/proceedings-template page, look for samples/sample-sigplan.tex as a guide. If you use Overleaf, be sure to change the documentclass option manuscript to sigplan. For ease of reviewing, please include page numbers in your submission using the LaTeX command \settopmatter{printfolios=true}. Please use the standard setting, e.g., the default font size for the SIGPLAN style is 10 point and the format uses two columns for the test.

All submissions need to be in PDF format. MPLR now uses double-blind reviewing. Authors should not show their names on a submission and should refer to their own work in third person. We further recommend that they avoid publicizing the work, at least under the same or similar title, while it is under review.

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.
