HYPAR Module
HYPAR is a parallelized version of the standard two-dimensional and three-dimensional HYDRUS computational modules (h2d_calc.exe and h3d_calc.exe). HYPAR uses parallel programming tools and techniques to take advantage of new multicore and/or multiprocessor computers and significantly speed up time-consuming simulations, especially those requiring a large number of finite elements. HYPAR currently supports only calculations in the direct mode (does not support the inverse mode), and it does not support any add-on modules (e.g., HP2, UnsatChem, Wetland, and/or C-Ride).
The name HYPAR (HyPar) is an acronym for "Hydrus Parallelized". The term, which has been suggested by Rien, is also intended to indicate a "Hyper" action when a multiple cores of a PC processor work in unison like 'a bunch of bees'.
