[HiW'20] Call for Talks
by Ben Gamari 16 Mar '20

16 Mar '20

Hello everyone, Haskell Implementors Workshop is calling for talk proposals. Co-located with ICFP, HiW is an ideal place to describe a Haskell library, a Haskell extension, compiler, works-in-progress, demo a new Haskell-related tool, or even propose future lines of Haskell development. The deadline for submissions is July 2nd 2020. Call for Talks ============== The 12th Haskell Implementors’ Workshop is to be held alongside ICFP 2020 this year in New Jersey. It is a forum for people involved in the design and development of Haskell implementations, tools, libraries, and supporting infrastructure, to share their work and discuss future directions and collaborations with others. Talks and/or demos are proposed by submitting an abstract, and selected by a small program committee. There will be no published proceedings. The workshop will be informal and interactive, with open spaces in the timetable and room for ad-hoc discussion, demos and lightning talks. Scope and Target Audience ------------------------- It is important to distinguish the Haskell Implementors’ Workshop from the Haskell Symposium which is also co-located with ICFP 2020. The Haskell Symposium is for the publication of Haskell-related research. In contrast, the Haskell Implementors’ Workshop will have no proceedings – although we will aim to make talk videos, slides and presented data available with the consent of the speakers. The Implementors’ Workshop is an ideal place to describe a Haskell extension, describe works-in-progress, demo a new Haskell-related tool, or even propose future lines of Haskell development. Members of the wider Haskell community encouraged to attend the workshop – we need your feedback to keep the Haskell ecosystem thriving. Students working with Haskell are specially encouraged to share their work. The scope covers any of the following topics. There may be some topics that people feel we’ve missed, so by all means submit a proposal even if it doesn’t fit exactly into one of these buckets: - Compilation techniques - Language features and extensions - Type system implementation - Concurrency and parallelism: language design and implementation - Performance, optimization and benchmarking - Virtual machines and run-time systems - Libraries and tools for development or deployment Talks ----- We invite proposals from potential speakers for talks and demonstrations. We are aiming for 20-minute talks with 5 minutes for questions and changeovers. We want to hear from people writing compilers, tools, or libraries, people with cool ideas for directions in which we should take the platform, proposals for new features to be implemented, and half-baked crazy ideas. Please submit a talk title and abstract of no more than 300 words. Submissions can be made via HotCRP at https://icfp-hiw20.hotcrp.com/ until July 2nd (anywhere on earth). We will also have lightning talks session. These have been very well received in recent years, and we aim to increase the time available to them. Lightning talks be ~7mins and are scheduled on the day of the workshop. Suggested topics for lightning talks are to present a single idea, a work-in-progress project, a problem to intrigue and perplex Haskell implementors, or simply to ask for feedback and collaborators. Logistics --------- We recognize the on-going threat that COVID-19 poses to our participants' safety. While August is nearly half a year away, we must account for the possibility that the virus continues to pose a significant threat into the summer. For this reason, we are investigating options that would allow remote presentations this year. In light of this, we urge potential presenters not to be discouraged from submitting and encourage participants to keep time open in their calendars, regardless of the on-going COVID situation. Rest assured that the conference organizers are working to ensure that the Implementors Workshop can be held safely and productively, regardless of how the COVID-19 situation evolves. Program Committee ----------------- - Andrey Mokhov (Newcastle University) - Ben Gamari (Well-Typed LLP) - Christian Baaij (QBayLogic) - George Karachalias (Tweag I/O) - Klara Marntirosian (KU Leuven) - Matthew Pickering (Univeristy of Bristol) - Ryan Scott (Indiana University Bloomington) Best wishes, Ben

The purpose of the meeting is to enable sharing of results, experiences, and novel ideas about how high-level, declarative techniques can help make high-performance, distributed/parallel, or numerically-intensive code dealing with computationally challenging problems easier to write, read, maintain, or portable to new hardware architectures. Areas of interest include, but are not limited to: * relevant compiler technologies * runtime systems (including fault tolerance mechanisms and those supporting distributed or parallel computation) * domain-specific languages (embedded or standalone) * type systems * formal methods * software libraries (e.g. for exact or interval arithmetic). Submission details ------------------ Submissions should fall into one of two categories: * Regular research papers (up to 12 pages) * Extended abstracts (1 - 2 pages) The bibliography will not be counted against the page limits for either category. Regular research papers are expected to present novel and interesting research results, and will be included in the formal proceedings. Extended abstracts should report work in progress that the authors would like to present at the workshop; they will be evaluated primarily for relevance and interest. Extended abstracts will be distributed to workshop attendees but will not be published in the formal proceedings. We welcome submissions from PC members (with the exception of the PC Chair(s)), but these submissions will be held to a higher standard. Submission is handled through the HotCRP site. All submissions should be in portable document format (PDF) and formatted using the ACM SIGPLAN style guidelines. Submissions written with LaTeX are required to use the acmart format and the two-column sigplan subformat (not to be confused with the one-column acmlarge subformat!). Extended abstracts must be submitted with the label ‘Extended abstract’ clearly in the title. Publication ----------- The proceedings of FHPNC 2020 will be published in the ACM Digital Library.
