The 39th IEEE International Performance Computing and Communications Conference (IEEE IPCCC 2020) will be held in Austin, Texas, USA, November 6--8, 2020. In addition to the main conference's technical program, IPCCC 2020 is soliciting proposals for one-day workshops to be held in conjunction with the main conference. Workshops on any topic related to the broad set of research and application areas covered by the IPCCC conference are welcome, particularly on topics that represent new research areas and directions. The workshops will be an integral part of IPCCC 2020 and will be fully incorporated into its logistical and budget planning process. Workshop papers will be published in the same set of proceedings as the main conference, and available on IEEE Xplore. At least one author of each accepted paper is required to register at the full registration rate, and needs to present the paper at the workshop. No-show workshop papers will be excluded from the conference proceedings.
