PSS®E-31 and all future planned releases use the Intel Visual FORTRAN (IVF) compiler. 2 i4 |3 j- a/ f; @1 J3 E% |
User-written software used with PSS®E-31 (e.g. Conec, Conet, user-written dynamics models, or ; P. G [: z. d2 J
programs that call USRCAS) must be compiled with Intel Visual FORTRAN (IVF) 9.1 or later (the : s' J- B$ U7 g6 b6 s
10.1 compiler is recommended). PTI cannot provide support for problems that arise when mixing - z/ T1 l u z! K
code from different compiler versions. ' A* C6 @6 L, @/ J8 O" I
Additional Notes 3 d1 a) r# X4 @& `- j* h# P** Please note that purchase of the compilers is not necessary to run PSS®E. The FORTRAN and 9 t* A6 J" `* ~& T xC run-time libraries will continue to be included with PSS®E, as in the past. The purchase of a - U4 {. T9 a- H
