parallel computing

Parallel computing is the simultaneous execution of some combination of multiple instances of programmed instructions and data on multiple processors in order to obtain results faster. The idea is based on the fact that the process of solving a problem usually can be divided into smaller tasks, which may be carried out simultaneously with some coordination. The technique was first put to practical use by ILLIAC IV in 1976, fully a decade after it was conceived.
