Unlike PDE1 and NAS-MG, complete program execution times are relevant for NAS-FT. Again, the benchmark size classes W and A are chosen, which are defined as follows: text/html 2016-10-30T18:41:14+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.sac-home.org/cases:nasft:implementation?rev=1477852874&do=diff Implementation Support for Complex Numbers SAC does not provide a built-in data type for the representation of complex numbers. However, they can easily be mimicked by vectors of two floating point numbers. The typedef construct allows to abstract from this implementation by introducing a user-defined type complex. With this type definition at hand, the usual arithmetic and relational operators can be overloaded with implementations on complex numbers. Embedding the type definition and a basic…
