Hello, Please, find below the call for papers for IFL 2019. With respect to the previous call, the deadline for submitting regular papers has been changed to June 15th. Please forward these to anyone you think may be interested. Apologies for any duplicates you may receive. best regards, Jurriaan Hage Publicity Chair of IFL --- ================================================================================ IFL 2019 31st Symposium on Implementation and Application of Functional Languages National University of Singapore September 25th-27th, 2019 http://2019.iflconference.org ================================================================================ ### Scope The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2019 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming. Topics of interest to IFL include, but are not limited to: - language concepts - type systems, type checking, type inferencing - compilation techniques - staged compilation - run-time function specialization - run-time code generation - partial evaluation - (abstract) interpretation - metaprogramming - generic programming - automatic program generation - array processing - concurrent/parallel programming - concurrent/parallel program execution - embedded systems - web applications - (embedded) domain specific languages - security - novel memory management techniques - run-time profiling performance measurements - debugging and tracing - virtual/abstract machine architectures - validation, verification of functional programs - tools and programming techniques - (industrial) applications ### Keynote Speaker * Olivier Danvy, Yale-NUS College ### Submissions and peer-review Differently from previous editions of IFL, IFL 2019 solicits two kinds of submissions: * Regular papers (12 pages including references) * Draft papers for presentations ('weak' limit between 8 and 15 pages) Regular papers will undergo a rigorous review by the program committee, and will be evaluated according to their correctness, novelty, originality, relevance, significance, and clarity. A set of regular papers will be conditionally accepted for publication. Authors of conditionally accepted papers will be provided with committee reviews along with a set of mandatory revisions. Regular papers not accepted for publication will be considered as draft papers, at the request of the author. Draft papers will be screened to make sure that they are within the scope of IFL, and will be accepted for presentation or rejected accordingly. Prior to the symposium: Authors of conditionally accepted papers and accepted presentations will submit a pre-proceedings version of their work that will appear in the draft proceedings distributed at the symposium. The draft proceedings does not constitute a formal publication. We require that at least one of the authors present the work at IFL 2019. After the symposium: Authors of conditionally accepted papers will submit a revised versions of their paper for the formal post-proceedings. The program committee will assess whether the mandatory revisions have been adequately addressed by the authors and thereby determines the final accept/reject status of the paper. Our interest is to ultimately accept all conditionally accepted papers. If you are an author of a conditionally accepted paper, please make sure that you address all the concerns of the reviewers. Authors of accepted presentations will be given the opportunity to incorporate the feedback from discussions at the symposium and will be invited to submit a revised full article for the formal post-proceedings. The program committee will evaluate these submissions according to their correctness, novelty, originality, relevance, significance, and clarity, and will thereby determine whether the paper is accepted or rejected. ### Publication The formal proceedings will appear in the International Conference Proceedings Series of the ACM Digital Library. At no time may work submitted to IFL be simultaneously submitted to other venues; submissions must adhere to ACM SIGPLAN's republication policy: http://www.sigplan.org/Resources/Policies/Republication ### Important dates Submission of regular papers: June 15, 2019 Submission of draft papers: July 15, 2019 Regular and draft papers notification: August 1, 2019 Deadline for early registration: August 15, 2019 Submission of pre-proceedings version: September 15, 2019 IFL Symposium: September 25-27, 2019 Submission of papers for post-proceedings: November 30, 2019 Notification of acceptance: January 31, 2020 Camera-ready version: February 29, 2020 ### Submission details All contributions must be written in English. Papers must use the ACM two columns conference format, which can be found at: http://www.acm.org/publications/proceedings-template Authors submit through EasyChair: https://easychair.org/conferences/?conf=ifl2019 ### Peter Landin Prize The Peter Landin Prize is awarded to the best paper presented at the symposium every year.

GPCE seeks conceptual, theoretical, empirical, and technical contributions to its topics of interest, which include but are not limited to: * program transformation, staging, macro systems, preprocessors, program synthesis, and code-recommendation systems, * domain-specific languages, language embedding, language design, and language workbenches, * feature-oriented programming, domain engineering, and feature interactions, * applications and properties of code generation, language implementation, and product-line development. Authors are welcome to check with the program co-chairs whether their planned papers are in scope. PAPER SELECTION The GPCE program committee will evaluate each submission according to the following selection criteria: * Novelty. Papers must present new ideas or evidence and place them appropriately within the context established by previous research in the field. * Significance. The results in the paper must have the potential to add to the state of the art or practice in significant ways. * Evidence. The paper must present evidence supporting its claims. Examples of evidence include formalizations and proofs, implemented systems, experimental results, statistical analyses, and case studies. * Clarity. The paper must present its contributions and results clearly. PAPER CATEGORIES GPCE solicits three kinds of submissions. * Full Papers reporting original and unpublished results of research that contribute to scientific knowledge in any GPCE topic listed above. Full paper submissions must not exceed 12 pages excluding bibliography. * Short Papers presenting unconventional ideas or visions about any GPCE topic listed above. Short papers do not always require complete results as in the case of a full paper. In this way, authors can introduce new ideas to the community and get early feedback. Please note that short papers are not intended to be position statements. Short papers are included in the proceedings and will be presented at the conference. Short paper submissions must not exceed 6 pages excluding bibliography. * Tool Demonstrations presenting tools for any GPCE topic listed above. Tools must be available for use and must not be purely commercial. Submissions must provide a tool description not exceeding 6 pages excluding bibliography and a separate demonstration outline including screenshots also not exceeding 6 pages. Tool demonstrations must have the keywords "Tool Demo" or "Tool Demonstration" in their title. If the submission is accepted, the tool description will be published in the proceedings. The demonstration outline will only be used by the program committee for evaluating the submission. PAPER SUBMISSION All submissions must use the ACM SIGPLAN Conference Format "acmart", using the "sigplan" sub-format, and 10 point font. Additional details and links to templates and the LaTeX class file can be found on the conference web site: https://conf.researchr.org/home/gpce-2019. To increase fairness in reviewing, a double-blind review process has become standard across SIGPLAN conferences. GPCE will follow a very lightweight model, where author identities are revealed to reviewers after submitting their initial reviews. Hence, the purpose is not to conceal author identities at all cost, but merely to provide reviewers with an unbiased first look at a submission. Author names and institutions should be omitted from submitted papers, and references to the authors' own related work should be in the third person. No other changes are necessary, and authors will not be penalized if reviewers are able to infer their identities in implicit ways. Papers must be submitted using HotCRP: https://gpce19.hotcrp.com/ For additional information, clarification, or answers to questions please contact the program co-chairs.

C FFI calls recap
by Adam 05 Jui '19

05 Jui '19

Hi Marc and list, Can you help me recap the speed aspect of C FFI use in C-compiled Scheme files: "Trampoline" in Gambit means specifically inter-module calls between C-compiled Scheme files, as well as call between binary backend-compiled code and C-compiled code, right. When you make a call to the C world from a C-compiled Scheme file, or vice versa when you call the Scheme world from the C world within a C-compiled Scheme file, I recall a bit of work takes place. This is not called a "trampoline" right, per above. It's called "continuation serialization", and which includes some Scheme stack and heap overflow checks? This work is an implied part of all the standard C FFI code forms |c-lambda| |c-define| |c-initialize| isn't it, also this is independent of compile mode e.g. (declare (not safe)), yes? About how heavy is it, per call? For even-higher-speed C access, such as doing tons of C or C++ acquire/release operations inlined in Scheme code, given acceptance of constraints on what my code does (to not overflow the Scheme stack/heap), can I use a C FFI form that does not do that? If so, which one is it - |##c-code|? Please clarify what I cannot do in |##c-code|. Thanks, Adam

Marc, Q:s re sequential consistency and critical sections in SMP Gambit
by Adam 02 Jui '19

02 Jui '19

Hi Marc, Below some questions about sequential consistency and critical sections in SMP Gambit. The Sutter slides below illustrate the problematique addressed beautifully. * Please have a look at the below and confirm that this is what Gambit does? * In thread-local code does Gambit internally do any optimizations that alters the execution order? In C-compiled code I presume the C compiler can make such optimizations, and that in itself pulls Gambit to need to address this problem domain. * The baseline constraint on Gambit's as well as any C compiler's optimizations are that optimizations that alter order will not span module-external calls, isn't it? * Does Gambit offer any low level primitives for (critical sections for) doing low level in-module sequentially consistent operations between cores? I.e. anything lower level than thread-send/receive and mutex-lock/unlock. What about fence, acquire/read fence, release/write fence. * Does Gambit guarantee that newly allocated objects have some initialization when accessed from any CPU core, or if malloc() gave trash then may a Gambit thread see trash? Example: Context: (define x #f) (##fence!) Core A: (set! x (vector 1 2)) Core B: (let loop () (let ((v x)) (if v (print (##vector-ref v 0))) (loop))) Which are all possible values that may be printed? C/C++ standardized SMP/memory model in the C11/C++11 specs. It's great to see Gambit spec the same now. Thanks, Adam Re critical sections, do you have primitives in SMP Gambit to force the compiler to respect them, and then in the code output produce assembly instructions that honor them? Today in SMP Gambit, I presume thread-send/receive and mutex-lock/unlock will abstract away the underlying architecture's memory model, and ensure that thread-receive will have access to the whole structure that thread-send sent. Example: GVM processor A: (thread-send B (list 1 2)) (define l (list 3 4)) (set-car! l 5) (thread-send B (list 1 2)) GVM processor B: (let loop () (for-each print (thread-receive) (loop)) This is to illustrate that thread-send/receive ensures that the list elements will be accessible (= read correctly) at the receiving site. In this case on any architecture, four print calls are done, each with the respectove argument: 1, 2, 5, 4. I guess that design feature is helped by that the Gambit compiler will not do optimizations that garble the code order, over module-external procedure calls, and thread-send/receive & mutex-lock/unlock count as procedures. I presume on strongly ordered architectures the following will make 2 3 go through: GVM processor A: (define l (list 1 2)) (thread-send B l) (set-car! l 3) GVM processor B: (define m (thread-receive)) (let loop ((i 0)) (if (not (eqv? (expt 3 12) i)) (loop (+ i 1))) (for-each print m) On a weakly ordered architecture the code would not SIGSEGV nor throw exception, but the first value could be 1 or 3. Importantly on a weakly ordered architecture the code would never cause a SIGSEGV, because Gambit's memory management ensures that pending memory bus transactions are flushed before it initiates collection of a dead object. Similarly any allocated object's space is immediately accessible on all cores: Common workup: (define s #f) GVM processor A: (set! s (make-u8vector 5)) GVM processor B: (let loop () (let ((v s)) (if v (##u8vector-ref v 1)) (loop)) The promise is limited to that the content is accessible only though - on a weakly ordered architecture, it may not have been initialized yet and therefore the type and range check in (u8vector-ref v 1) could fail, (##u8vector-ref v 1) do not do that though and while it may return junk, at least it will not crash. The above two described behaviors are is in symmetry with any host OS' malloc/free.

27 Mai '19

Hello, Please, find below the call for papers for IFL 2019. Please forward these to anyone you think may be interested. Apologies for any duplicates you may receive. best regards, Jurriaan Hage Publicity Chair of IFL --- ================================================================================ IFL 2019 31st Symposium on Implementation and Application of Functional Languages National University of Singapore September 25th-27th, 2019 http://2019.iflconference.org ================================================================================ ### Scope The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2019 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming. Topics of interest to IFL include, but are not limited to: - language concepts - type systems, type checking, type inferencing - compilation techniques - staged compilation - run-time function specialization - run-time code generation - partial evaluation - (abstract) interpretation - metaprogramming - generic programming - automatic program generation - array processing - concurrent/parallel programming - concurrent/parallel program execution - embedded systems - web applications - (embedded) domain specific languages - security - novel memory management techniques - run-time profiling performance measurements - debugging and tracing - virtual/abstract machine architectures - validation, verification of functional programs - tools and programming techniques - (industrial) applications ### Keynote Speaker * Olivier Danvy, Yale-NUS College ### Submissions and peer-review Differently from previous editions of IFL, IFL 2019 solicits two kinds of submissions: * Regular papers (12 pages including references) * Draft papers for presentations ('weak' limit between 8 and 15 pages) Regular papers will undergo a rigorous review by the program committee, and will be evaluated according to their correctness, novelty, originality, relevance, significance, and clarity. A set of regular papers will be conditionally accepted for publication. Authors of conditionally accepted papers will be provided with committee reviews along with a set of mandatory revisions. Regular papers not accepted for publication will be considered as draft papers, at the request of the author. Draft papers will be screened to make sure that they are within the scope of IFL, and will be accepted for presentation or rejected accordingly. Prior to the symposium: Authors of conditionally accepted papers and accepted presentations will submit a pre-proceedings version of their work that will appear in the draft proceedings distributed at the symposium. The draft proceedings does not constitute a formal publication. We require that at least one of the authors present the work at IFL 2019. After the symposium: Authors of conditionally accepted papers will submit a revised versions of their paper for the formal post-proceedings. The program committee will assess whether the mandatory revisions have been adequately addressed by the authors and thereby determines the final accept/reject status of the paper. Our interest is to ultimately accept all conditionally accepted papers. If you are an author of a conditionally accepted paper, please make sure that you address all the concerns of the reviewers. Authors of accepted presentations will be given the opportunity to incorporate the feedback from discussions at the symposium and will be invited to submit a revised full article for the formal post-proceedings. The program committee will evaluate these submissions according to their correctness, novelty, originality, relevance, significance, and clarity, and will thereby determine whether the paper is accepted or rejected. ### Publication The formal proceedings will appear in the International Conference Proceedings Series of the ACM Digital Library. At no time may work submitted to IFL be simultaneously submitted to other venues; submissions must adhere to ACM SIGPLAN's republication policy: http://www.sigplan.org/Resources/Policies/Republication ### Important dates Submission of regular papers: May 31, 2019 Submission of draft papers: July 15, 2019 Regular and draft papers notification: August 1, 2019 Deadline for early registration: August 15, 2019 Submission of pre-proceedings version: September 15, 2019 IFL Symposium: September 25-27, 2019 Submission of papers for post-proceedings: November 30, 2019 Notification of acceptance: January 31, 2020 Camera-ready version: February 29, 2020 ### Submission details All contributions must be written in English. Papers must use the ACM two columns conference format, which can be found at: http://www.acm.org/publications/proceedings-template Authors submit through EasyChair: https://easychair.org/conferences/?conf=ifl2019 ### Peter Landin Prize The Peter Landin Prize is awarded to the best paper presented at the symposium every year. The honored article is selected by the program committee based on the submissions received for the formal review process. The prize carries a cash award equivalent to 150 Euros. ### Organization and Program committee Chairs: Jurrien Stutterheim (Standard Chartered Bank Singapore), Wei Ngan Chin (National University of Singapore) Program Committee: - Olaf Chitil, University of Kent - Clemens Grelck, University of Amsterdam - Daisuke Kimura, Toho University - Pieter Koopman, Radboud University - Tamas Kozsik, Eotvos Lorand University - Roman Leschinskiy, Facebook - Ben Lippmeier, The University of New South Wales - Marco T.

[TFP'19 and TFPIE'19] call for participation
by Peter Achten 21 Mai '19

21 Mai '19

--------------------------------- C A L L F O R P A R T I C I P A T I O N --------------------------------- ====== TFP 2019 ====== 20th Symposium on Trends in Functional Programming 12-14 June, 2019 Vancouver, BC, CA https://www.tfp2019.org/index.html ====== TFPIE 2019 ====== 8th International Workshop on Trends in Functional Programming in Education 11 June, 2019 Vancouver, BC, CA http://www.staff.science.uu.nl/~hage0101/tfpie2019/index.html The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions (see below at scope). Please be aware that TFP uses two distinct rounds of submissions (see below at submission details). TFP 2019 will be the main event of a pair of functional programming events. TFP 2019 will be accompanied by the International Workshop on Trends in Functional Programming in Education (TFPIE), which will take place on June 11. == Invited Speakers == TFP 2019 is pleased to announce keynote talks by the following two invited speakers: Nikhil Swamy, Microsoft Research: Structuring the Verification of Imperative Programs with Functional Programming Frank Wood, University of British Columbia: Probabilistic Programming TFPIE 2019 is pleased to have the following invited speaker: Gregor Kiczales: Functional Programming at the Core of a High Throughput Software Engineering Curriculum == Scope == The symposium recognizes that new trends may arise through various routes. As part of the Symposium's focus on trends we therefore identify the following five article categories. High-quality articles are solicited in any of these categories: Research Articles: Leading-edge, previously unpublished research work Position Articles: On what new trends should or should not be Project Articles: Descriptions of recently started new projects Evaluation Articles: What lessons can be drawn from a finished project Overview Articles: Summarizing work with respect to a trendy subject Articles must be original and not simultaneously submitted for publication to any other forum. They may consider any aspect of functional programming: theoretical, implementation-oriented, or experience-oriented. Applications of functional programming techniques to other languages are also within the scope of the symposium. Topics suitable for the symposium include, but are not limited to: Functional programming and multicore/manycore computing Functional programming in the cloud High performance functional computing Extra-functional (behavioural) properties of functional programs Dependently typed functional programming Validation and verification of functional programs Debugging and profiling for functional languages Functional programming in different application areas: security, mobility, telecommunications applications, embedded systems, global computing, grids, etc. Interoperability with imperative programming languages Novel memory management techniques Program analysis and transformation techniques Empirical performance studies Abstract/virtual machines and compilers for functional languages (Embedded) domain specific languages New implementation strategies Any new emerging trend in the functional programming area If you are in doubt on whether your article is within the scope of TFP, please contact the TFP 2019 program chairs, William J. Bowman and Ron Garcia. == Best Paper Awards == To reward excellent contributions, TFP awards a prize for the best paper accepted for the formal proceedings. TFP traditionally pays special attention to research students, acknowledging that students are almost by definition part of new subject trends. A student paper is one for which the authors state that the paper is mainly the work of students, the students are listed as first authors, and a student would present the paper. A prize for the best student paper is awarded each year. In both cases, it is the PC of TFP that awards the prize. In case the best paper happens to be a student paper, that paper will then receive both prizes. == Instructions to Author == Papers must be submitted at: https://easychair.org/conferences/?conf=tfp2019 Authors of papers have the choice of having their contributions formally reviewed either before or after the Symposium. == Pre-symposium formal review == Papers to be formally reviewed before the symposium should be submitted before an early deadline and receive their reviews and notification of acceptance for both presentation and publication before the symposium. A paper that has been rejected in this process may still be accepted for presentation at the symposium, but will not be considered for the post-symposium formal review. == Post-symposium formal review == Papers submitted for post-symposium review (draft papers) will receive minimal reviews and notification of acceptance for presentation at the symposium. Authors of draft papers will be invited to submit revised papers based on the feedback received at the symposium. A post-symposium refereeing process will then select a subset of these articles for formal publication. == Paper categories == There are two types of submission, each of which can be submitted either for pre-symposium or post-symposium review: Extended abstracts. Extended abstracts are 4 to 10 pages in length. Full papers. Full papers are up to 20 pages in length. Each submission also belongs to a category: research position project evaluation overview paper Each submission should clearly indicate to which category it belongs. Additionally, a draft paper submission—of either type (extended abstract or full paper) and any category—can be considered a student paper. A student paper is one for which primary authors are research students and the majority of the work described was carried out by the students. The submission should indicate that it is a student paper. Student papers will receive additional feedback from the PC shortly after the symposium has taken place and before the post-symposium submission deadline. Feedback is only provided for accepted student papers, i.e., papers submitted for presentation and post-symposium formal review that are accepted for presentation. If a student paper is rejected for presentation, then it receives no further feedback and cannot be submitted for post-symposium review. == Format == Papers must be written in English, and written using the LNCS style. For more information about formatting please consult the Springer LNCS web site (http://www.springer.com/lncs) == Program Committee == Program Co-chairs William J.
