iWAPT 2021 Program

Reminder about IPDPS 2021 registration: All papers in the workshop must have one author registered at full (non-student) fee. It is assumed that all attendees to the workshop will be registered with IPDPS 2021 to give access to the proceedings and to all live events and recorded sessions of the conference.

iWAPT is held in limited live sessions for about 2 hours for discussions and Q&A, and the online discussion forum using slack.
Please take the time to view the presentation video with slides before the live session and join in the live sessions or post your questions into slack by registering/joining the slack workspace: https://iwapt.slack.com/join/shared_invite/zt-pfxa7c1v-BCN8CjO0Kn5XKpddvFRefw#/
Zoom URL is available on IPDPS web system. After registration, please check e-mail from "noreply at rdmobile.com". (The e-mail title is "Begin Your IPDPS Experience".)
In the live sessions, chairs will read all questions from slack to four papers and presenters will answer them. Session time (40 minutes) is not split into four papers.
