/******************************************************* Mosel Example Problems ====================== file runrtpardistr.java ``````````````````````` Running several instances of a model remotely from a host program. - Parallel submodels in distributed architecture - Before running this model, you need to set up the NODENAMES with a machine name/address of your local network. All nodes that are used need to have the same version of Xpress installed and suitably licensed, and the server "xprmsrv" must have been started on this machine.
