 Cray T90

The Cray T90 series (code-named "Triton" during development) was the last of a line of vector processing supercomputers manufactured by Cray Research, Inc, superseding the Cray C90 series.The first machines were shipped in 1995, and featured a 2.2 ns (450 MHz) clock cycle and two-wide vector pipes, for a peak speed of 1.8 gigaflops per processor; the high clock speed arises from the CPUs being built using ECL logic.
