Report on IPDPS 2021

Excerpt from the Proceedings Message of the 2021 General Co-Chairs:

We are pleased to be able to welcome you to the 35th edition of the IEEE International Parallel and Distributed Processing Symposium (IPDPS 2021). This is the second year that we are unable to meet up in person, but we have had a chance to improve our virtual meeting skills, so we are hoping to provide an online meeting experience that gives good value to attendees and helps showcase the invited speakers and the contributed papers that make up the program for this year. We had looked forward to holding the conference in Portland, Oregon, but what a difference a year makes.

We have all had varying experiences in meeting the challenges of the pandemic year, personally and professionally, but our international community has coalesced to carry on the networking and collaboration required to organize a conference of this caliber. We believe that the heart and soul of the conference is as vibrant as ever and that the same level of rigor and the usual high standards of previous years have been supported to create the technical content of the main conference and eighteen workshops.

While the program committee conducted their work for the main conference, and the workshops solicited submissions and invited speakers, the organizers explored the options for presenting the conference virtually. In parallel, the Computer Society Conference Services staff were building their toolkit for supporting the virtual conference format. Further, most of the conference community were also learning how to conduct their research and educational programs in virtual and online and remote modes. Thus, our first expression of gratitude goes to the IPDPS community who have stayed the course with us, and to all of you who stepped up to serve on committees and to organize the programs that are part of IPDPS 2021.

On Monday and Friday, the eighteen workshops will conduct their online programs, utilizing several virtual platforms and providing live and asynchronous discussions. This year we were able to restore the PhD Forum to our program, and on Monday there will be breakout sessions for presenting and discussing the fourteen posters accepted for the conference. The Main Conference program on Tuesday, Wednesday, and Thursday includes four keynote talks and 22 technical sessions of contributed papers, including the plenary Best Papers session on Wednesday.
