—Dynamic load balancing both within and between constituent subsystems is required to achieve ultrascalabil-ity in coupled multiphysics and multiscale models. Intercon-stituent dynamic load balancing requires runtime resizing—or malleability—of subsystem processing element (PE) cohorts. In our previous work, we developed and introduced the Malleable Model(More)
High-precision accelerator modeling is essential for particle accelerator design and optimization. However, this modeling presents a significant computational challenge. We discuss performance modeling of and computational quality of service (CQoS) results from Synergia2, an advanced particle accelerator simulation code developed under the ComPASS SciDAC-2(More)
