ABSTRACT:
Scalability and time-to-solution studies have historically been focused on the size of the problem and run time. We consider a more strict definition of “solution” whereby a live data analysis provides continuous and reconfigurable insight into massively parallel simulations. Specifically, we used the Argonne ALCF’s Blue Gene/P machine with 163,840 cores tightly linked through a high-speed network to 100 visualization nodes that share 200 GPUs. Two meshes with 416M and 3.3B elements discretize the flow over a full swept wing with an unsteady synthetic jet. The 416M element mesh takes about 2 seconds per flow solve step including the extraction and rendering of a slice or a contour, slowing currently the simulation by only 10 and 15% respectively. The 3.3B element case proved scalable at about 15 seconds per time step. This work will be presented with informational slides combined with a looping video and live demonstrations of our software.
