- Replaced the overloaded Cray Y-MP
-
Much cheaper to run than the Y-MP (power and maintenance)
- Twice the capacity and 4 times the memory
-
32 vector processors, binary compatible with the Y-MP
-
200 Mflop/sec sustainable performance
- Eight 333 Mflop processors of the Y-MP8 to the thirty-two 200 Mflop processors of the J90
- More like a parallel processing system
-
Unicos Operating System
