Call for Presentations
All developers and users of LLVM and related sub-projects are invited to present at the first virtual 2020 LLVM Developers’ Meeting!
We are looking for the following proposals:
- Technical Talks (25-30 minutes including Q&A):
- LLVM Infrastructure,Clang and all related sub-projects
- On uses of LLVM in academia or industry
- On new projects using Clang or LLVM
- Tutorials (60 minutes)
In depth talks on LLVM infrastructure or other core libraries, tools, etc. Demos encouraged.
- Student Research Competition Technical Talks & Poster (20-25 minutes including Q&A)
Talks from students using LLVM, Clang, and all sub-projects in research.
The audience usually votes on a winner.
- Lightning Talks (5 minutes, no questions, no discussions)
Quick talks about a use or improvement of LLVM and other sub-projects.
- Birds of a Feather (30 minutes)
Historically these are informal and ad-hoc, but at our meeting they are prepared in advance and are guided discussions (usually with a slide deck) about a specific topic. For informal and ad-hoc, please consider a Round Table (details to come).
- Panels (30-60 minutes)
Panels may discuss any topic as long as it’s relevant to LLVM or related sub-projects. Panels can take many forms, but a common format is to begin with short introductions from each panel member, and follow with an interactive dialogue among the panelists and audience members. Panels should consist of at least 3 people and have a moderator.
- Posters (1 hour session)
Posters presenting work using LLVM and related subprojects. Poster presenters will answer questions from attendees and give mini presentations.
As this conference is virtual and our very first, we are still working out the numerous details. The length of the talk types below are subject to change, but the above gives you an idea of what we expect. The majority of the talks will be pre-recorded except for panels, birds of a feather, posters, and possibly lightning talks. In addition, we will be requiring most speakers to participate in some form of live Q&A. Time zones are a huge challenge with a virtual conference and we will do our best to be reasonable in our expectations.
The timeframe for submission is also much tighter due to allowing time for speakers to record and us to process videos. We apologize for the inconvenience.
The submission deadline is July 20, 2020 at 11:59PM PDT.
Please submit your proposal here:
For each proposal, please submit a title, short abstract, submission type, abstract for the website, include who the speakers or panel member/moderators are, and provide a more detailed description of the talk through an extended PDF abstract. We highly recommend you consult and follow the guide at the end of this CFP when submitting your proposal.
When will I be notified of acceptance?
Our goal is to notify all submissions by July 31, 2020.
When is the conference?
In order to not conflict with another large virtual conference, we have moved the 2020 LLVM Developers’ Meeting to October 6-8. The exact times of the conference are still under discussion.
Should I register if I have submitted a proposal?
Given this is a virtual conference and we have less space restrictions and a different fee structure, you can register at any time before the registration deadline. We will be providing details on registration in July.
When will the recordings be due?
Recordings should be completed by September 14.
Will I be required to have a video camera?
We do not want the lack of recording equipment to prevent submissions and will be sorting out options to help those without recording equipment available. Please stay tuned for details.
When will my live Q&A be?
As the conference is virtual, our attendees and speakers will be in many different time zones. We won’t know the program until closer to the event and then we can start to form a schedule. Our schedule will attempt to meet the needs of many time zones, but will not be a perfect solution. You may be asked to give a live Q&A early in the morning, late at night, or multiple times.
Who is on the program committee?
The program committee is composed of active developers of the LLVM, Clang, and related sub-communities. The website will be updated with the list of the program committee members.
I have a question, who do I contact?
