%'cluster_command': creates the command string for launching jobs in the cluster

% NbProcess: number of processes in the list, these processed are grouped by the systwm into jobs dipatched to NbCore cores
% NbCore: number of computer cores to which the processes are dispatched
% CPUTimeProcess: estimated CPU time for an individual process (in min)
