High Quality Content by WIKIPEDIA articles! 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. As with the Cray J90, each CPU contained a scalar data cache, in addition to the instruction buffering/caching which has always been in Cray architectures.
