Thrust is the C++ parallel algorithms library which inspired the introduction of parallel algorithms to the C++ Standard Library.
The first use of SIMD instructions was in the ILLIAC IV, which was completed in 1966.. SIMD was the basis for vector supercomputers of the early 1970s such as the CDC Star-100 and the Texas Instruments ASC, which could operate on a "vector" of data with a single instruction.Vector processing was especially popularized by Cray in the 1970s and 1980s.
