Performance analysis of distributed parallel systems

The demand to economic high performance computers that do complex computationsvery fast is increasing day by day. In this thesis, a parallel machine with the aid of PVM(Parallel Virtual Machine) is set by using computers which are installed Linux operatingsystem. XPVM is used as an interface between the computers and the user. The communicationbetween computers are provided by Ethernet. The general performance of the system is affectedby the number of processors and the problem size. Therefore the performance analysis ofparallel systems is very important. PVM is a library which has linkable functions to provideinformation transfer between processes. In this study, parallel programs have been run bychanging the problem size and the number of processors. The system performance was observedfor each condition. The program activity graph had been obtained, and the performance isexamined. The optimum performance points were found in terms of the problem size and thenumber of processors by looking at the analysis results.
