3.5.10 F90_T3D

Compile for the T3D, this has only minor effects, for instance some compiler directives like

!DIR$ IVDEP

are changed to

!DIR$

The first directive is required on a Cray vector machines for correct vectorization, but it gives a warning on the T3D.

In addition the STOPCAR file will not be read on the T3D on each iteration (see previous subsection), because re-reading the STOPCAR file is too expensive (0.5-1 sec) on a T3D. The F90_T3D flag must also be specified if the scaLAPACK flag is used on the T3D, because the T3D requires that some arrays are allocated in a special way (shmem-allocation).
