Runprime - Remote model execution

Description
  • runprimedistr.c, runprimedistr.java, runprimedistr.mos: Running a model on a remote Mosel instance (requires prime.mos)
  • runprimeiodistr.c, runprimeiodistr.java: Running a model on a remote Mosel instance and retrieving output data: data saved to file or in memory on the remote machine (requires primeio.mos)
  • runprimeiodistr2.c, runprimeiodistr2.java: Running a model on a remote Mosel instance and retrieving output data: data saved in memory on the local machine. Implementation of a file manager for data exchange in memory (requires primeio.mos)
  • runprimeiodistr3.c, runprimeiodistr3.java: Running a model on a remote Mosel instance and retrieving output data: data saved to a file on the local machine (requires primeio.mos)
  • runprimeiodistr.mos: mmjobs implementation. Running a model on a remote Mosel instance and retrieving output data (requires primeio.mos)
