Flynn's classical taxonomy
Parallel computers can be classified in at least four ways:
- Single Instruction stream Single Data stream (SISD)
- Single Instruction stream Multiple Data stream (SIMD)
- Multiple Instruction stream Single Data stream (MISD)
- Multiple Instruction stream Multiple Data stream (MIMD)
These classifications are discussed in more detail in the Appendix:
Michael J. Flynn proposed this classification in 1966, and it is still in use today. The Cray-1 and the CDC 7600 supercomputer discussed in the following sections are of the SISD class. Use the following link to learn more about Flynn: https://en.wikipedia.org/wiki/Flynn's_taxonomy.
