Shen, Yuying Nan, Zhibiao Bellotti, Bill Robertson, Michael Chen, Wen Shao, Xinqing Exiting the Simile model (e.g., before initializing an updated version) will delete the pipe or socket. Resetting the Simile model will cause it to accept a new connection for each submodel instance. It is up to the remote system to close the pipes at the end of its run, which signals Simile also to pause. The two systems then exchange data over the pipe as the models run, as described in the next section. These can all be made to the same server location. If the submodel is multiple-instance, Simile will accept one client connection for each instance. The remote system can then connect as a client. When the model is initialized, Simile opens a connection as the server at the given location. if you enter 'year' while the Simile time unit is default or 'day', then the Simile model will advance 365 units for each time unit in the remote model. At the start of the simulation, Simile works out the offset between the times as represented on each system, but if the unit is something other than 'day' on the remote system it must be entered here. Default is 'none', meaning no command is issued. This can be used if it is possible to run the remote model from the command line, in order to save the modeller from having to start the remote model via its own interface at this point. This is a system command that is called to start the remote model each time the Simile model is initialized or reset. The dialogue for specifying the remote interaction has two other fields: #RUNNING APSIM COMMAND LINE WINDOWS#Selecting remote connection allows the modeller to enter the name of the connection, which can be anything in Windows but must be an available filesystem location in MacOS or Linux. Note that the commands in c# to operate on named pipes work unchanged on Unix sockets in these systems, allowing remote models implemented in c# to be cross-platform. Communication is via named pipe in Windows, or Unix socket (which is the closest equivalent to a Windows named pipe) in MacOS or Linux. Implementation of the connectionįor these reasons, we have built a remote connection interface specification into Simile itself, and this can be selected as a third option, after normal execution or use of external procedure, in the Submodel Properties dialogue. Also, in the case of a multi-instance submodel, the external procedure is called once for each instance in sequence, meaning it is hard to avoid problems if the remote process is running the instances in some other order. However, doing communication this way would require the procedure to be manually re-written each time a change was made to the format of data being passed back and forth while developing the combined model. It is possible to implement such communication using externally-supplied procedures as described in the previous section, but supplying a procedure that carries out communication with another process rather than implementing the submodel itself. For instance, one might use Simile to create a farm-scale or larger model of an agricultural system, but want to use existing models in another tool such as APSIM for the various crops and soils in the system The purpose of this feature is to enable systems to be modelled where individual components in different modelling environments must run in combination, and each system has its own means of managing execution. Simile version 6.11 introduces the ability for a submodel to incorporate communication with a separate application during model execution.
