Subcommand

Description
The number of hosts nhosts is provided on the command line, followed by nhosts lines containing the keyword *HOSTiPVM (i=1,...,nhosts) and the name of the host. The wild card * must be a unique identifier if more than one iTOUGH2-PVM applications are run simultaneously. The name of the host must be identical to that appended to the file name of the iTOUGH2 executable on that specific machine. A host (especially a multiprocessor machine) may be named several times in the list of hosts. The parent process must not be included in the list. However, a child process can be spawned on the parent host. If the Levenberg-Marquardt algorithm is used, parallelization can be restricted to the evaluation of the Jacobian matrix by using keyword JACOBIAN on the command line. The parent process can be suspended for isleep seconds each time it checks for incoming residuals (default: isleep = 1).
