re: “This hardware is for VERY large databases (2,000,000 records x 1012 fields), and very large spreadsheet calcs happening simultaneously.”
Ya .. I’ve got a Win 7 box I run a 3D EM ‘solver’ on, using FEM where an object is described via ‘tets’ (tetrahedrons) ... the smaller the tet the better the resolution, so the trick is to _not_ over-run installed memory in a PC/machine by wisely choosing the tet size and orientation. Some antennas are longer than wide, so, one can adjust resolution to ‘fit’ memory!
