The Promise of Load Balancing the Parameterization of Moist Convection Using a Model Data Load Index
White Paper The parameterization of physical processes in atmospheric general circulation models contributes to load imbalances among individual processors of message-passing distributed-multiprocessor systems. Load imbalances increase the overall time to... [10 Jul 2008]
Load Balancing for the Numerical Solution of the Navier-Stokes Equations
White Paper In particular, it studies the application of the Extrapolated DiFfusion (EDF) method for the efficient parallelization of a simple 'atmospheric' model, which involves the numerical solution of the steady state Navier-Stokes (NS) equations in the... [10 Jul 2008]
Photos: Supercomputers signal when storms are a-brewing
Photo Since it started in 1975 ECMWF's climate model has evolved from simply simulating atmospheric data to recreating its interaction with animals and plants, land, ocean and ice. In order to replicate the uncertainty of atmospheric systems ECMWF uses a... [06 Jun 2008]
Comparing Linux Clusters for the Community Climate System Model
White Paper Specifically, the authors examine the execution time and scalability of the Community Atmospheric Model (CAM) and the Parallel Ocean Program (POP) on Linux clusters with Intel Xeon and AMD Opteron processors, using Dolphin, Myrinet, and Infiniband... [01 Apr 2007]
