CRAY J90 is shared-memory multi-vector supercomputer with 1 - 32 processors.
The system has one multiply and add vector pipe set per CPU at a clock cycle of 2.2 ns which results in a theoretical peak performance of 1.8 GFlops.
In the CRAY T90 system there are no separate scalar processor and scalar and vector code have to share the same functional units. A small scalar cache is added to speed up scalar calculations.
The system main memory capacity is 8 GB.
The system maximum performance is 58 GFlops.
The operating system is UNICOS (Cray Unix variant).
The year of introduction is 1995.
