On-Site or Remote Participation?

For those who wish to attend SC remotely, we’re preparing a robust conference experience served through the SC21 HUBB remote content platform. Please review the FAQ below. It will help you decide if remote participation is right for you.

On-site attendees will be able to access remote content according to what’s included with their corresponding registration category.

To understand the measures taken for on-site participation, please review the guidelines on the Health & Safety page. We will continue to closely monitor dynamics surrounding COVID-19 as they impact SC and will provide updates with any developments.

For Attendees

How will SC21 content be delivered to remote attendees?

SC21 has chosen a new remote content provider to deliver the SC21 HUBB remote content experience, available on desktop and mobile app. We are working to provide single sign-in and syncing of custom schedules across all devices.

Will remote content be live-streamed and/or on-demand?

The majority of remote content will be synchronously live-streamed as the on-site SC schedule progresses throughout the week, with the exception of Tutorials. Recordings of all live-streamed sessions will be made available on-demand approximately 6 hours after each session occurs. For some programs, only select sessions will be live-streamed (please see below).

What will be available in the SC21 HUBB?

We intend to make available as much of the in-person program as possible, with the exception of receptions, lunches, and other on-site-only events. Please review the registration category accordions on the Registration page for what is and isn’t included with remote participation.

Please note:

  • Birds of a Feather: All sessions will be available via Zoom rooms, and only the TOP500 and Green500 Bofs will be live-streamed and available on-demand.
  • Tutorials: Only select sessions will be available on-demand (no live-steam), they will be pre-recorded, and will be available asynchronously on Sunday, November 14. Tutorials NOT appearing in the SC21 HUBB are designated with a blue In-Person Only tag in the Schedule.
  • Workshops: All sessions will be available via Zoom rooms, but only select sessions will be live-streamed and available on-demand.
  • Exhibits: Exhibitors are being offered space to promote their products and services in the SC21 HUBB. Attendees can expect booth Zoom rooms, special promotions, and more. A listing of exhibitors choosing to have representation in the SC21 HUBB will be made available closer to the conference.
  • Students@SC: Student programming will be available via Zoom rooms hosted through the SC21 HUBB, available to all registered attendees.

How do I register for remote participation and how much does it cost?

All on-site registrations will receive SC21 HUBB access corresponding with what’s included with their chosen registration category. Please check the Registration page for remote content included with each registration category.

How long will content be available on-demand?

All on-demand content will be available through January 31, 2022.

For Presenters

Do I need to be on-site to present?

We strongly encourage presenters to present on-site. However, if presenting on-site isn’t feasible, you may have the chance to submit a pre-recorded presentation and/or participate remotely via live-stream. Please contact your Program Chair as soon as possible in order to discuss options if there are dynamics impacting your ability to present on-site.

Do I need to register to present remotely?

Yes. Registration is mandatory for all presenters, and all are required to register at the on-site rate whether they present on-site or remotely.

Will I be required to sign a Video Consent Form (VCF) in order to present?

Yes. Signing the VCF to present is mandatory for all presenters whether they present on-site or remotely. Those who choose to not sign the VCF will not be allowed to present.

Will my paper be published even though I cannot present it in person?

Yes. All accepted papers will be published regardless of whether they are presented on-site or remotely, but they must be presented.

Will session Q&A be available for remote attendees on the SC21 HUBB?

Q&A will be available for all sessions delivered through the SC21 HUBB. More details to come.
