Air quality modeling on massively parallel computers
Abstract
The use of massively parallel computers provides an avenue to overcome the computational requirements of air quality modeling. General considerations on parallel implementation of air quality models are outlined including domain decomposition. The implementation of the CIT urban photochemical model on the Intel Touchstone Delta, a distributed memory multiple instruction/multiple data (MIMD) machine is described. When both the transport and chemistry portions of the model are parallelized, a speed-up of about 30 is achieved using 256 processors.
