Seems like they claimed a max of 35 gflops. Anyone have some >specifics? > rpalmer@dz.inre.asu.edu Here is a summary from the catalogue. The price is not mentioned. The nominal theoretical peak is 32 GFlops not 35. The information is translated inofficially from Japanese by the present poster. No guarantee of the correctness of the translation.

Yoshio Oyanagi ------------------------------------------------------------------------------- Hitachi's New Vector Supercomputer On March 31, 1992, Hitachi Ltd. announced new series of vector supercomputers, HITAC S-3800 and HITAC S-3600. S-3800 can consitute a multiprocessor system and the pipeline pitch is estimated to be 2 nano seconds. These are the third generation of HITAC supercomputers, following HITAC S-810 and S-820. For the first time in Hitachi super- computers, they support OSF (unix) operating system. (This paragraph is my comment, not from the catalogue.) S-3800 has six models: 160, 180, 182, 260, 280, 480. The first digit shows the number of processors, the second the speed and the last digit 2 shows that the system has two scalar units in one processor. The specification is as follows Model: 160 180 182 260 280 480 Max performance (GFlops)4 8 8 8 16 32 #scalar units 1 1 2 2 2 4 #vector units 1 1 1 2 2 4 (Hitachi calls scalar/vector processors instead of units.)

Two kinds of operating systems: HI-OSF/1-MJ(Unix) and VOS3/AS(MVS-like). ------------------------------------------------------------------------------
