Parallel InterfaceA parallel interface accepts input for processing on a variety of systems simultaneously. Web search programs which submit the same request to a variety of search sites use such an interface.
Parallel processing involves the simultaneous use of more than one computer or processor to solve a problem. In the classic application, a complex problem is partitioned into individual tasks that are allocated separately. The processors may then cooperate in solving the problem or run completely independently. Load balancing attempts to keep all processors busy by moving tasks from heavily loaded processors to less loaded ones.
In single instruction/multiple data (SIMD) mode, many processing elements perform the same operations on different data. In multiple instruction/multiple data (MIMD) mode, each processor executes different instructions. Parallel interface search programs on the Web use SIMD.
