Method for determining an optimal frequency for execution of a software application

A method for determining an optimal frequency (fo) for the execution of a software application on an information processing system, comprising

• executing, for a first time, the application at a predetermined frequency (fd) to determine an overall execution time (Tg) and an overall energy consumption (Eg);
• executing, for a second time, the application at the predetermined frequency (fd), by means of a measurement tool, to determine measurements that include at least one of an overall execution time (Tg*), a time corresponding to the inputs-outputs of the software application (TIO*), and a time one calls to a management and communication system (TMPI*) measurements on the execution of the application;
• determining a first law providing an execution time (t(f)) as a function of the frequency (f), and a second law providing an energy consumption (E(f)) as a function of the frequency (f);
• and
• determining the optimal frequency (fo) as a frequency optimizing a criterion (C(f)) combining the execution time and the energy consumption, as a function of the frequency.
