Abstract: The invention deals with a method to control deployment of a program to be executed across a cluster of machines (M1-Mn), the method comprising steps of: measuring (102) an amount of available material resources at each machine (M1-Mn), determining (306) processes (P1-P5) of the program to be executed in parallel, for each process (P1-P5), estimating (308) an amount of material resources required for execution of the process, allocating (400) processes (P1-P5) to machines in the cluster on the basis of the amounts of measured material resources at each of the different machines and the estimated amounts of required resources, requesting installing a process allocated to a machine in said machine, if the process is not already installed in said machine.
