User program measurement in a time-shared environment

ABSTRACT

A general discussion of the measurement of software systems is followed by a description of a hardware and software scheme for measuring user programs in a time-shared environment. The TX-2 computer at MIT Lincoln Laboratory was used for the implementation of such a system and the characteristics of this implementation are reported. A scenario showing the system in use is presented. Finally, it is shown how other time-sharing systems may provide similar measuring facilities.
