Each evaluation study often uses a different model and / or data set, making it impossible to directly compare the performance and computational efficiency of various approaches that simulate the same aerosol process. (pnnl.gov)
It makes extensive use of template metaprogramming to achieve high computational efficiency. (qmcpack.org)
These range from the inability to resolve sub-grid features of the topography, approximations made for computational efficiency, the necessarily incomplete physical scope of the models and inevitable coding bugs. (realclimate.org)
