—There is a significant, established code base in the scientific computing community. Some of these codes have been parallelized already but are now encountering scalability issues due to poor data locality, inefficient data distributions, or load imbalance. In this work, we introduce a new abstraction called loop chaining in which a sequence of parallel(More)
Structured-grid PDE solver frameworks parallelize over boxes, which are rectangular domains of cells or faces in a structured grid. In the Chombo framework, the box sizes are typically 16<sup>3</sup> or 32<sup>3</sup>, but larger box sizes such as 128<sup>3</sup> would result in less surface area and therefore less storage, copying, and/or ghost cells(More)
