The large workflow of the Square Kilometre Array (SKA) Phase 1 scale was successfully executed on the world’s fastest supercomputer Summit, as demonstrated in this movie. At its peak execution, 4561 compute nodes (Note: Summit has a total of 4608 nodes) are used, marking a milestone of astronomical data challenge.
