Abstract

Method for regulating in real time the clock frequencies of at least one cluster of electronic machines, characterized in that it provides for carrying out the following steps: a) defining a finite number of discrete virtual capacity values f[l], f[2],.... 00 f[K], as global performance indices, of said cluster of machines; b) calculating by means of a randomized optimization procedure, for each value of said virtual capacity, a set of 1 vectors containing clock frequency values for each machine in said cluster; c) defin 00 ing a reference queue value, related to the number of processing requests received by said cluster; and provides for iteratively carry ing out the following steps: d) measuring the deviation between a current queue value, related to the number of processing requests in said current queue, and said reference queue value; e) selecting one of said discrete virtual capacity values on the basis of said » measured deviation, said selection occurring on the basis of a procedure that, at each iteration, analyzes said measured deviation, o compares it with the measured deviation value obtained at the previous iteration, and chooses whether to keep the current virtual ca - pacity value or to adopt one of the two adjacent or non-adjacent admissible virtual capacity values of said finite number of discrete values; f) selecting, based on said selected virtual capacity value, a vector of clock frequency values for each machine from said set o of 1 vectors, so as to optimize a multi-target performance index (J), and then setting the clock frequency of each machine in the cluster
