Dear Smalltalk friends Please find the following conference call for papers that can interest you. If you know other forums that could be interested in virtual machines, compilers …. do not hesitate to forward this call. S. Ducasse and C. Scholliers PC chair of MPLR 26 ################################################################################## The 23rd 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). https://2026.ecoop.org/home/mplr-2026 Important Dates --------------- - Abstract Submission Deadline: February 27, 2026 - Paper Submission Deadline: March 6, 2026 - Paper Author Notification: April 15, 2026 - Camera Ready for Papers: April 30, 2026 - Conference Date: June 29, 2026 All deadlines are 23:59 AoE (UTC-12h). #### Topics The areas of interest related to managed programming languages and runtime systems include but are not limited to: - **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 - Domain-specific languages - Security and privacy - Persistence - **Languages and Compilers** - Managed languages - Compilers and interpreters - Type systems and program logics - Language interoperability - Parallelism, distribution, and concurrency - **Techniques, Tools, and Applications** - Static and dynamic program analysis - Testing and debugging - Simulation - Refactorings - Program synthesis - 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 ’26 or if you have any other questions, please do not hesitate to contact the Program Chair. #### 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 2026 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 #### 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.
