Accelerate AERMOD model runtimes with parallel processing
BREEZE developers are leaders in the development of high-performance computing models for air dispersion modeling. Our software developers were the first to tackle the complex process of developing parallel software for US EPA regulatory dispersion models. To comply with The Guideline on Air Quality Models, BREEZE developers were challenged with leaving the AERMOD mathematical algorithms unchanged while at the same time incorporating sophisticated CPU management routines to handle the simultaneous calculations among multiple processors. They succeeded in June 2007 with the introduction of BREEZE AERMOD Parallel. In addition to AERMOD Parallel, BREEZE had parallelized various internal processing routines incorporated in many BREEZE products (e.g., gridding methods and doublet theory).
Due to advances in scientific knowledge, higher resolution raw data, stringent air quality standards, and changing regulations, environmental modeling is demanding more and more from EHS professionals and their computers. All of these influences can cause AERMOD model runs to take significant amounts of time. Instead of minutes, AERMOD runtimes for large projects can take days or even weeks on a single-core computer.
To address the issue of increased runtimes, BREEZE offers a couple of options to modelers to increase productivity while managing model complexity. The options available for BREEZE AERMOD users interested in parallel processing include local and remote resources. (Note: A two-core local parallel processing version is included in BREEZE AERMOD.)
