A massivelyparallel, high-performance computing system is particularly sensitive tooperating system overhead. Traditional, multi-purpose, operating systemsare designed to support a wide range of usage models and requirements.To support the range of needs, a large number of system processes areprovided and are often inter-dependent on each other. The computingoverhead of these processes leads to an unpredictable amount ofprocessor time available to a parallel application. A very commonparallel programming model is referred to as the bulk synchronousparallel model which often employs MPI for communication. Thesynchronization events are made at specific points in the applicationcode. If one processor takes longer to reach that point than all theother processors, everyone must wait. The overall finish time isincreased. Unpredictable operating system overhead is one significantreason a processor might take longer to reach the synchronization pointthan the others.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 84 pp. Englisch.
