Numerical Wind Tunnel (数値風洞) was an early implementation of the vector parallel architecture developed in a joint project between National Aerospace Laboratory of Japan and Fujitsu.
It was the first supercomputer with a sustained performance of close to 100 Gflop/s for a wide range of fluid dynamics application programs.
[1][2][3][4] With 140 cores, the Numerical Wind Tunnel reached a Rmax[5] of 124.0 GFlop/s and a Rpeak[6] of 235.8 GFlop/s in November 1993.
[2] It consisted of parallel connected 166 vector processors with a gate delay as low as 60 ps in the Ga-As chips.
Each processor board was equipped with 256 Megabytes of central memory.
