What are some of the practical applications of CSP process algebra?

Question

CSP is used for the description and representation of concurrent systems, how it is used in practice (theoretically and programmatically)?

What are the application areas (other than concurrent and parallel systems) where it is used?

Answer 1

One of the most celebrated applications of CSP and was the use of the CSP tool FDR in the analysis of the Needham-Schroeder protocol. It has had other applications in analyzing protocols and software design.

Answer 2

CSP is the formal basis of the programming language Occam which compiled to INMOS Transputers. Transputers appeared in all sorts of devices, such as set-top boxes for satellite TV. Eventually, however, the company doing all of this work failed to achieve commercial success, and was eventually absorbed by another company.
