CGRA accelerator for weather/climate dynamics simulation

摘要

A coarse-grained reconfigurable array accelerator for solving partial differential equations for problems on a regular grid is provided. The regular grid comprises grid cells which are representative for a physical natural environment wherein a list of physical values is associated with each grid cell. The accelerator comprises configurable processing elements in an accelerator-internal grid connected by an accelerator-internal interconnect system and memory arrays comprising memory cells. The memory arrays are connected to the accelerator-internal interconnect system. Selected ones of the memory arrays are positioned within the accelerator corresponding to positions of the grid cells in the physical natural environment. Thereby, each group of the memory cells is adapted for storing the list of physical values of the corresponding grid cell of the physical natural environment.
