Extending scalability of the community atmosphere model

Extending scalability of the community atmosphere model

The Community Atmosphere Model (CAM) is the atmosphere component of the Community Climate System Model (CCSM), and is the largest consumer of computing resources in typical CCSM simulations. The parallel implementation of the Community Atmosphere Model (CAM) employs a number of different domain decompositions. Currently, each decomposition must utilize the same number of MPI processes, limiting...

Improving the performance scalability of the community atmosphere model

The Community Atmosphere Model (CAM), which serves as the atmosphere component of the Community Climate System Model (CCSM), is currently the most computationally expensive CCSM component in typical configurations. Improving performance scalability in CAM has been a challenge, due largely to algorithmic restrictions necessitated by the polar singularities in its latitude-longitude computational...
