Report Parallelisation of LESSTAG(Publicatie)In this paper, the optimization and parallelisation of the program LESSTAG, developed at the University of Twente is described. Method: MPI, speedup: 20, field: Large Eddy Simulation.
Short description of the program
The current Large Eddy Simulation (LES) model was first developed in 1995 (published in Water Resources Research in 1996) to study the effects of spatially variable surface properties on areal averaged momentum and scalar (heat and water vapour) transport at the land-atmosphere interface. At a later stage the LES model was coupled to a remote sensing based soil-vegetation-atmosphere-transfer (SVAT) scheme, or land surface model (LSM), in order to study the feedback effects between surface state and spatial variability in fluxes, through the induction of spatial variability in the lower atmosphere.
