Supercomputing Asia 2021 (SCA21), March 1-4, 2021, will be held in Singapore and will be hybrid (both physical and virtual). Given the success of the Asia Pacific Research Platform (APRP) virtual session, held at APAN 50 on August 4, 2020, an expanded APRP session is being planned for SCA21. The Program Committee envisions presentations and discussions on the progress and coordination of the growing Research Platform ecosystem. More details to come.
