A PVM Executive Program For Use With RELAP5-3D

PDF Version Also Available for Download.

Description

An executive program has been developed that coordinates the coupling of any number of other computer programs to perform integrated analyses of nuclear power reactor systems and related experimental facilities. The ability to couple programs allows the analyst to apply different analytical models to specific domains in the problem to achieve accurate results. The coupling is accomplished using the PVM message passing software and the executive program manages all phases of a coupled computation. It starts up and configures a PVM virtual machine, spawns all of the coupled processes on the PVM virtual machine, coordinates the time step size between ... continued below

Description

An executive program has been developed that coordinates the coupling of any number of other computer programs to perform integrated analyses of nuclear power reactor systems and related experimental facilities. The ability to couple programs allows the analyst to apply different analytical models to specific domains in the problem to achieve accurate results. The coupling is accomplished using the PVM message passing software and the executive program manages all phases of a coupled computation. It starts up and configures a PVM virtual machine, spawns all of the coupled processes on the PVM virtual machine, coordinates the time step size between the coupled codes, manages the production of printed and plottable output as well as restart files, and shuts the PVM virtual machine down at the end of the computation. The executive program also monitors the status of the coupled computation, repeating time steps as needed to obtain an accurate solution and terminating a coupled computation gracefully if one of the coupled processes is terminated by the computational node on which it is executing. This paper discusses the application of the executive to RELAP5-3D.
