Important Disclaimer:  ASPLOS 2023 will be held primarily in person in Vancouver, BC.  Registration for remote attendance is provided on this site for those interested in attending but unable to travel to Vancouver or wishing to reduce their carbon footprint. There are important caveats as follows. The remote attendance option will be provided on a “best effort” basis for the main conference days ONLY (Monday-Wednesday, March 27-29). The remote option only includes (1) remote access to live-streamed video/audio of main conference paper presentations, provided via Zoom; and (2) keynote sessions live-streamed via Zoom. The remote option may include the opportunity to participate in mentoring programs (Meet-a-Senior-Architect or Meet-a-Senior-Student) based on the availability and schedules of mentors. “Best effort” means there will likely be issues with poor and/or missing sound and video and our volunteers will try their best to resolve them but that remote attendees must be willing to entirely miss a talk or even multiple talks they wanted to see/hear and/or not be able to fully hear what is being said during some talks especially by in person attendees asking questions. Questions from remote attendees will be limited to those submitted via Whova text chat and may only be answered asynchronously via a text chat response and only after the in person question and answer period has ended and though the organizers will encourage authors to respond to these questions whether a response is provided will be entirely at individual speakers’ discretion.

All in-person attendees are required to acknowledge the COVID-19 waiver as part of the registration process. Please review the COVID-19 waiver information.

The main conference registration includes a complimentary Banquet Ticket, but registrations for Workshops and Tutorials do not include a complimentary Banquet Ticket.

Please support the conference and the SIG by staying at the conference hotel.
Why stay at the conference hotel? It’s the center of conference activity, that’s why!  You’ll be able to network easily with other conference attendees. It’s a quick trip to get to the program and functions, and just as quick to nip back your room for a break. You’ll have a better conference experience. That’s obvious. But there are other reasons that you need to consider before you look at another hotel. 

  • The conference leaders have taken their role of finding a conference site very seriously. They looked at a number of locations. The needs of attendees as individuals were considered as well as the need for conference meeting spaces.   
  • Everyone enjoys meeting in a comfortable conference venue, offering quality service and support for workshops, tutorials, plenary sessions, etc. As the quid-pro-quo for that service and support, the conference guarantees that a percentage of attendees will stay in the hotel. The hotel generally discounts the rate for conference attendees from their normal charges.
  • The hotel rates are negotiated based on the number of expected attendees and the meeting space required to comfortably accommodate them. The basis for negotiation with the hotel is statistics from that conference in prior years. The contract with the hotel then guarantees specific numbers of sleeping rooms will be used each night during the conference. A complex negotiation of meeting room space, functions, and events (with food), and sleeping room provides the most value per dollar for the conference and those attending it.  
  • If the conference does not meet the contracted sleeping room commitment, the hotel gets paid anyway. Unfilled rooms can cost the conference thousands of dollars. (The conference does not get credit for the re-sale of sleeping rooms unless the hotel is completely filled.)   The next conference in the series cannot negotiate as beneficial a hotel contract, and the registration fee is then under pressure to increase unreasonably. 
  • On occasion, one of the many internet providers or sometimes the hotel itself will offer a few rooms in their inventory at a lower price than the conference is offering. There are often restrictions and penalties associated with these rates. If you somehow obtain a better rate than the one offered by the conference, your stay will still be counted toward our required room block. 
  • What if we don’t contract for sleeping rooms? Attendees will pay more to stay at the conference hotel. The conference will incur additional expenses for meeting room rental fees, which can be quite costly. The hotel will not hold a block of rooms for attendees, which may leave some people quite a distance from the conference venue. In short, the conference ends up with higher expenses, many of those attending will pay a higher price for their hotel rooms, future conference registration fees will be pushed higher.
