Call for Papers

Workshop on Virtual Machines and Language Implementations (VMIL’23)

Co-located with SPLASH 2023
October 22-27, 2023, Cascais, Portugal

https://2023.splashcon.org/home/vmil-2023
========================================================================

The concept of Virtual Machines is pervasive in the design and implementation of programming systems. Virtual Machines and the languages they implement are crucial in the specification, implementation and/or user-facing deployment of most programming technologies.

The VMIL workshop is a forum for researchers and cutting-edge practitioners in language virtual machines, the intermediate languages they use, and related issues.

The workshop is intended to be welcoming to a wide range of topics and perspectives, covering all areas relevant to the workshop’s theme. Aspects of interest include, but are not limited to:

- design issues in VMs and IRs (e.g. IR design, VM modularity, polyglotism);
- compilation (static and dynamic compilation strategies, optimizations, data representations);
- memory management;
- security considerations;
- concurrency (both internal and user-facing);
- performance engineering;
- tool support and related infrastructure (profiling, debugging, liveness, persistence);
- the experience of VM development (use of high-level languages, bootstrapping and self-hosting, reusability, portability, developer tooling, etc.);
- empirical studies on related topics, such as usage patterns, the usability of languages or tools, experimental methodology, or benchmark design;
- the use of VMs in teaching programming, programming languages, and programming language implementation.

----------------------------------
Submission Guidelines
----------------------------------

We invite high-quality papers in the following two categories:

- Research and experience papers: These submissions should describe work that advances the current state of the art in the above or related areas. The suggested length of these submissions is 6–10 pages (maximum 10 pages, excluding references).

- Work-in-progress or position papers: These papers should document ongoing efforts in an area of interest which have not yet yielded final results, and/or should present and defend the authors’ position on a topic related to the broad area of the workshop. The maximum length of these submissions is 6 pages, but we will consider shorter submissions (e.g. a well-written 2-page abstract).

Submissions will be judged on novelty, clarity, timeliness, relevance, and potential to stimulate discussion during the workshop.
The workshop has two submission deadlines. For the first submission deadline, we will consider all paper types. For the second deadline, we will consider only work-in-progress and position papers.
Regardless of the submission deadline, all accepted papers will be published in the ACM Digital Library, except if the authors prefer not to be included.

      novelty, technical rigor, and contribution to the state-of-the-art.

   Format: up to 12 pages, excluding bibliography and appendix

 2. Work-in-progress research papers

      describing 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 new ideas instead of

      technical rigor and experimental results.

   Format: up to 6 pages, excluding bibliography and appendix

 3. 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

 4. Posters and Demonstrations

      They will be evaluated similarly to work-in-progress papers.

      Posters can accompany any submission as a way to provide additional

      demonstration and discussion opportunities.



    Format: poster and 1-page abstract

Accepted submissions will be published in the ACM Digital Library,

except if the authors prefer not to be included.

MPLR 2023 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 `acmart` format with the `sigconf` style:

[rvm-research] [CfP] 7th International Workshop on Modern Language Runtimes, Ecosystems, and VMs: Deadline Jan 22 AoE

[Stefan M. <ji...@st...>]

============================================================================
              Call for Extended Abstracts and Talks: MoreVMs’23

                       7th International Workshop on
               Modern Language Runtimes, Ecosystems, and VMs

                     Co-located with ‹Programming›’23
             March 13rd to 17th, 2023, Tokyo, Japan

         https://2023.programming-conference.org/home/MoreVMs-2023
============================================================================

The 7th MoreVMs 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, compilation strategies, as
well as the interaction of modern languages and runtimes with operating systems
and modern hardware architectures. 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. MoreVMs welcomes early-stage work, emerging ideas, insightful
discussions of existing systems, as well as extended abstracts for publication
in the ACM DL. 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 developments environments
 - Interaction of virtual machines, operating systems, and computer architecture
 - Case studies of existing language implementation approaches
 - Language implementation challenges and trade-offs
 - Surveys and usage reports to understand usage in the wild
 - Survey and analysis of existing VMs and compilers
 - 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. We will also
consider submissions in form of blog posts. These can be submitted either as
HTML files or URL, as well as a brief (ca. 100 word) abstract for the workshop
website. The extended abstracts, talk proposals, and if the speakers wish,
their slides, will be published on the workshop’s website. Extended abstracts
can be published as part of the companion of ‹Programming›’23 in the ACM DL.
Publication in the ACM DL is conditional on the acceptance by the program
committee. Please note that MoreVMs’23 is organized as an academic workshop,
and as such, speakers will be required to register for the workshop.

[Stefan M. <ji...@st...>]

============================================================================
              Call for Extended Abstracts and Talks: MoreVMs'23

                              7th Workshop on
                  Modern Language Runtimes and Ecosystems

                      Co-located with <Programming>'23
                  March 13rd to 17th, 2023, Tokyo, Japan

        https://2023.programming-conference.org/home/MoreVMs-2023
============================================================================


The 7th MoreVMs 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, compilation strategies, 
as well as the interaction of modern languages and runtimes with operating 
systems and modern hardware architectures. 
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.



MoreVMs welcomes early-stage work, emerging ideas, insightful discussions of 
existing systems, as well as extended abstracts for publication in the ACM DL.



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
 - Interaction of virtual machines, operating systems, and computer architecture
 - Case studies of existing language implementation approaches
 - Language implementation challenges and trade-offs
 - Surveys and usage reports to understand usage in the wild
 - Survey and analysis of existing VMs and compilers
 - 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. 
We will also consider submissions in form of blog posts. These can be submitted 
either as HTML files or URL, as well as a brief (ca. 100 word) abstract for the 
workshop website. 

The extended abstracts, talk proposals, and if the speakers wish, their slides, 
will be published on the workshop's website. Extended abstracts can be published 
as part of the companion of <Programming>'23 in the ACM DL. Publication in the 
ACM DL is conditional on the acceptance by the program committee.

Please note that MoreVMs'23 is organized as an academic workshop, and as such, 
speakers will be required to register for the workshop.

[rvm-research] [CFP] 2022 Workshop on Virtual Machines and Language Implementations @ SLASH 2022

[Christos-efthymios K. <Chr...@ma...>]

========================================================================
Call for Papers

Workshop on Virtual Machines and Language Implementations (VMIL’22)

Co-located with SPLASH 2022
December 05, 2022, Auckland, New Zealand

https://2022.splashcon.org/home/vmil-2022<https://2021.splashcon.org/home/vmil-2021>
Follow us on twitter @VMIL2022
========================================================================

The concept of virtual machines is pervasive in the design and
implementation of programming systems. Virtual machines and the
languages they implement are crucial in the specification,
implementation and/or user-facing deployment of most programming
technologies.

VMIL 2022 will have a hybrid model, though the details are yet to be
fully worked out. You can keep up to date with the hybrid conference
model on SPLASH's web site: https://2022.splashcon.org<https://2021.splashcon.org/>

The workshop is intended to be welcoming to a wide range of topics and
perspectives, covering all areas relevant to the workshop’s theme.
Aspects of interest include, but are not limited to:

- design issues in VMs and IRs (e.g. IR design, VM modularity, polyglotism);
- compilation (static and dynamic compilation strategies, optimizations,
data representations);
- memory management;
- concurrency (both internal and user-facing);
- tool support and related infrastructure (profiling, debugging,
liveness, persistence);
- the experience of VM development (use of high-level languages,
bootstrapping and self-hosting, reusability, portability, developer
tooling, etc).
- empirical studies on related topics, such as usage patterns, the
usability of languages or tools, experimental methodology, or benchmark
design.


Submission Guidelines
---------------------

We invite high-quality papers in the following two categories:

  * Research and experience papers: These submissions should describe
work that advances the current state of the art in the above or related
areas. The suggested length of these submissions is 6–10 pages (maximum
10pp, excluding references).

  * Work-in-progress or position papers: These papers should document
ongoing efforts in an area of interest which have not yet yielded final
results, and/or should present and defend the authors’ position on a
topic related to the broad area of the workshop. The maximum length of
these submissions is 6 pages, but we will consider shorter submissions
(e.g. a well-written 2-page abstract).

For the first submission deadline, all paper types are considered for
publication in the ACM Digital Library, except if the authors prefer not
to be included. Publication of work-in-progress and position papers at
VMIL is not intended to preclude later publication elsewhere.

Submissions will be judged on novelty, clarity, timeliness, relevance,
and potential to stimulate discussion during the workshop.

For the second deadline, we will consider only work-in-progress and
position papers. Abstracts do not have to be submitted before the
deadline. These will not be published in the ACM DL, and will only
appear on the website.

The address of the submission site is: https://vmil22.hotcrp.com<https://vmil22.hotcrp.com/>


Important Dates
---------------

All deadlines are Anywhere on Earth (AoE), i.e., UTC-12h

Unfortunately no. But here are two tips:

- Build BaseBase (prototype) or BaseAdaptive (prototype-opt), depending on what you need in your tests. They build a lot faster than FullAdaptive (development) or FastAdaptive (production).

- Is the build taking longer than a minute? Try a different machine if so. :)

I wanted to know if there’s a way to partially compile the RVM.

I am asking because I want to debug the code I’ve written, and right now, the compilation is taking too long and it’s impossible to debug.

Onward! is more radical, more visionary, and more open than other conferences to ideas that are well-argued but not yet proven. We welcome different ways of thinking about, approaching, and reporting on programming language and software engineering research.


Submissions Due: 8 May 2021

** Onward! Essays **

Onward! Essays conference is looking for clear and compelling pieces of writing about topics important to the software community construed broadly. An essay can be an exploration of a topic, its impact, or the circumstances of its creation; it can present a personal view of what is, explore a terrain, or lead the reader in an act of discovery; it can be a philosophical digression or a deep analysis. It can describe a personal journey, perhaps that by which the author reached an understanding of such a topic. The subject area should be interpreted broadly and can include the relationship of software to human endeavours, or its philosophical, sociological, psychological, historical, or anthropological underpinnings.

**** DSM’21 ****

Domain-Specific Modeling (DSM) languages provide a viable and time-tested solution for continuing to raise the level of abstraction, and thus productivity, beyond coding, making systems and software development faster and easier.

In DSM, the models are constructed using concepts that represent things in the application domain, not concepts of a given programming language. The modeling language follows the domain abstractions and semantics, allowing developers to perceive them-selves as working directly with domain concepts. Together with frameworks and platforms, DSM can automate a large portion of software production.

The goals of the workshop are to share experiences and demonstrate the DSM solutions that have been developed by both researchers and practitioners, identify research questions and continuing to build the community.


Submissions due: 6 August 2021

https://2021.splashcon.org/home/dsm-2021


**** HATRA 2021 ****

Programming language designers seek to provide strong tools to help developers reason about their programs. For example, the formal methods community seeks to enable developers to prove correctness properties of their code, and type system designers seek to exclude classes of undesirable behavior from programs. The security community creates tools to help developers achieve their security goals. In order to make these approaches as effective as possible for developers, recent work has integrated approaches from human-computer interaction research into programming language design.


This workshop brings together programming languages, software engineering, security, and human-computer interaction researchers to investigate methods for making languages that provide stronger safety properties more effective for programmers and software engineers.


Submissions due: 6 August 2021

**** LIVE 2021 ****

Programming is cognitively demanding, and too difficult. LIVE is a workshop exploring new user interfaces that improve the immediacy, usability, and learnability of programming. Whereas PL research traditionally focuses on programs, LIVE focuses more on the activity of programming.

The LIVE 2021 workshop invites submissions of ideas for improving the immediacy, usability, and learnability of programming. Live programming gives the programmer immediate feedback on the behavior of a program as it is edited, replacing the edit-compile-debug cycle with a fluid programming experience. The best-known example of live programming is the spreadsheet, but there are many others.


Submissions due: 6 August 2021

https://2021.splashcon.org/home/live-2021


**** REBLS 2021 ****

Reactive programming and event-based programming are two closely related programming styles that are becoming ever more important with the advent of advanced HPC technology and the ever increasing requirement for our applications to run on the web or on collaborating mobile devices. A number of publications on middleware and language design — so-called reactive and event-based languages and systems (REBLS) — have already seen the light, but the field still raises several questions. For example, the interaction with mainstream language concepts is poorly understood, implementation technology is in its infancy and modularity mechanisms are almost totally lacking.


This workshop will gather researchers in reactive and event-based languages and systems. The goal of the workshop is to exchange new technical research results and to define better the field by coming up with taxonomies and overviews of the existing work.


Submissions due: 6 August 2021

https://2021.splashcon.org/home/rebls-2021


**** VMIL 2021 ****

The concept of Virtual Machines is pervasive in the design and implementation of programming systems. Virtual Machines and the languages they implement are crucial in the specification, implementation and/or user-facing deployment of most programming technologies.

The VMIL workshop is a forum for researchers and cutting-edge practitioners in language virtual machines, the intermediate languages they use, and related issues.

Submissions due: 6 August 2021

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


The 18th 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).

This year, MPLR will be held in Munster, Germany, as permitted
considering the health and safety concerns. We expect there will be a
mix of in-person and remote attendance options for the event.

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, ...)
    Portable intermediate representations like Webassembly
    Domain-specific languages
    Language design
    Compilers and interpreters
    Type systems and program logics
    Language interoperability
    Parallelism, distribution, and concurrency

MPLR'21 or if you have any other questions, please do not hesitate to
contact the Program Chair (jeremy dot singer at glasgow dot ac dot
uk).


Submission Categories
=====================

MPLR accepts four 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)
    
    Posters, which will be evaluated similarly to work-in-progress
    papers. Posters can accompany any submission as a way to provide
    additional demonstration and discussion opportunities. (Format:
    poster and 1-page abstract)

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

MPLR 2021 submissions must conform to the ACM Policy on Prior
Publication and Simultaneous Submissions and to the SIGPLAN
Republication Policy.

Submissions need to use the ACM acmart format with the sigconf style.

Re: [rvm-research] [External Email] Re: IR class wrap around NormalMethod

[Kenan L. <kl...@bi...>]

Hi David,

Thank you so much for the prompt response!

I did find the way how it replaces HIR instructions with runtime
routines in ExpandRuntimeServices.java but missed there are inlining calls
cases ;-)
Thanks to point it out, it really helps.

Thanks,
Kenan

Hi,

	Take a look at ExpandRuntimeServices.java (
https://github.com/JikesRVM/JikesRVM/blob/master/rvm/src/org/jikesrvm/compilers/opt/hir2lir/ExpandRuntimeServices.java
). This code is replacing HIR instructions like NEW with calls to runtime
routines, then immediately inlining those calls.    You should be able to
do something similar to add your instrumentation.

[rvm-research] IR class wrap around NormalMethod

[Kenan L. <kl...@bi...>]

Hi,

I have a few questions regarding the behavior after the instrumentation
inserted into the code as IR.


   - When the user-defined methods inserted into the opt compiler. Let's
   say, inserting the IR in the stage of hir2lir. Would the compiler treat
   this IR/NormalMethod as the real method? To clarify it, does this
   instrumentation would introduce the real method invocations or it would be
   inlined automatically?
   - If the IR instrumentation is treated as a method, is there any way
   that I can explicitly inline it?
   - If the answers for both questions above are no. Is there any way that
   I can add instrumentations without introducing extra method invocations?

Thanks,
Kenan

java.lang.String is a fairly complicated class with many other classes it
depends on for full functionality.  Atom is much simpler, and thus easier
to use in restricted environments (Uninterruptible code; early in VM
booting before full Java language functionality is available.)

Re: [rvm-research] [External Email] Re: Quick Question about genThreadSwitchTest code Intention

[Khaled Z M. <kma...@bi...>]

Hi,

Thanks for your explanation.
So, anything between Point A and Point B will be jumped over if the
condition is met.
Is my understanding correct ? I had a reverse understanding of it.


Point A - fr1 = asm.forwardJcc(EQ)
          ..........
Point B -  fr1.resolve(asm);

Generally yes, but there are caveats.  See JNIFunctions.java for comments.
The implementation is mostly complete at the JNI 1.4 level, but even then
there are gaps.
