Parallel computing is the simultaneous execution of the same task (split up and specially adapted) 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.
Approaches to parallel computers include:
- Computer cluster
- Parallel supercomputers
- Distributed computing
- NUMA vs. SMP vs. massively parallel computer systems
- Grid computing
