Fremgangsmåde til indstilling af prioritetsniveauer i et multiprogram computersystem med prioritetsfastlæggelse, multiprogram computersystem og program dertil

摘要

A method for setting priority levels in a multiprogramming computer system (1) with priority scheduling, in which threads (15, 16, 17) of execution of each process (13, 14) have a standard priority level, comprises measuring relative use of one or more processors (2) in the system (1) by the threads (15, 16, 17) of execution of a process (13, 14). The priority levels of one or more threads (15, 16, 17) of execution are lowered if their measured relative use exceeds a certain escalation threshold for the duration of an escalation time period (DT1).
