Composite Theoretical Performance

Computer hardware export license requirements are evaluated according to
Composite Theoretical Performance (CTP), which replaced the former
Processing Data Rate (PDR) parameter. CTP is measured in Million
Theoretical Operations Per Second (MTOPS). CTP was developed by the U.S.
as a new parameter, and was adopted by CoCom during the Core List
negotiations, because PDR was not applicable to certain modern computer
architectures such as vector processors, massively parallel processors, and
array processors. CTP is designed to measure all of these architectures,
as well as signal processing equipment.
