  GeneralThe heart of Distributed Computing is the Main Controller which acts as a broker of information between the front ends and the solvers. The front ends submit jobs to the Main Controller which then distributes those jobs to the solver computers available within the network. The system also controls the transmission of status messages as well as the transfer of result data back to the front end.
  The Main Controller may connect to an arbitrary number of front ends on one hand and to an arbitrary number of solvers on the other hand.
  Each computer designated to run simulation jobs needs to have a Solver Server installed locally. The purpose of this server is to maintain communication with the Main Controller and to locally run and control the solver’s executables.
  The following diagram illustrates this system:
  
  Once a solver has been started remotely, the corresponding solver server communicates directly with the respective front end concerning status messages. This strategy helps to reduce network traffic through the Main Controller which otherwise may become a bottleneck for the flow of information.
  Communication within the distributed computing system is done via TCP/IP by using fixed ports. Make sure that the firewalls are properly configured such that communication channels can be established.
  The front end stores the actual job data within a subfolder contained in the project’s main folder. This subfolder is named DC. The data are then sent to the Main Controller and stored locally in the queue folder. The Main Controller needs to have only local file access to its queue folder so that no further network load is generated by accessing files on a network drive. However, since this folder may contain large amounts of data, make sure that sufficient disk space is available.
  Once the job is submitted from the Main Controller to a Solver Server, the job’s data are transferred and stored locally on the Solver Server’s disk. When the simulation has finished, the data are automatically transferred back to the Main Controller’s disk and deleted on the Solver Server’s disk. Therefore the Solver Server needs to store data for the currently simulated project only, but the available disk space should still be  sufficiently large.
  The simulated data will then reside on the Main Controller until the corresponding front end has successfully transferred the data back to the local disk for further post processing operations. Afterwards, the data are deleted from the Main Controller’s disk.
  This system also allows disconnecting the front end from the Distributed Computing system while the simulation is running even for parameter sweeps. Once the front end is connected to the system again, it will automatically receive all previously computed simulation results for the currently opened project.
  So far, we have focused on the basic architecture of the Distributed Computing system. In the next section we will explain the installation and configuration of both the Main Controller and the Solver Server.
  The front end does not require any special setup procedures other than the specification of the Main Controller’s computer name and TCP/IP port (File Network Computing):
  
  

  
  Main ControllerThe main controller needs to be installed on one computer in the network only. The computer does not necessarily have to have any other components of CST STUDIO SUITE™ installed.
  The installation of the Main Controller is very similar to the installation of the other components. Once you are prompted for the installation type, select Custom to open the following dialog box:
  
  

  
  At the bottom of the list of features, find an entry named Distributed Computing System – Main Controller. Clicking on the down arrow next to the corresponding icon will open a context menu. Select “This feature will be installed on local hard drive” to change the icon from a red cross to a hard drive symbol. In the same way, you may de-select all other components such as the Program Files, Dongle Drivers, License Server and Example Files by selecting “This feature will not be available” in the corresponding context menus.
  
  The following picture shows the dialog box and how the feature list should look for the installation of the Main Controller only:
  

  
  Afterwards you can complete the installation of the component as usual. Once the installation is finished the Main Controller’s administration panel can be invoked via the start menu beyond CST STUDIO SUITE Distributed Computing System Main Controller Administration.
  

  Here you need to specify a Working directory where all network job data will be stored until the simulation results have successfully been transferred back to the front end. It is highly recommended to use a local hard drive to avoid unnecessary network traffic. The amount of data stored within this folder may become significant, so make sure to have sufficient disk space available.
  Furthermore, you need to specify the TCP/IP Server port which will then be used by the Main Controller for communicating with both the front ends and the solver servers. Make sure that your firewall (if any) is configured such that this port can be accessed properly.
  You also need to set a Reference installation directory which is used as a source for the automatic update which keeps the DC network the same version.
  Furthermore it can be chosen whether a log file should be written. Try to restart unfinished jobs when starting is an option for the unlikely case when the main controller is stopped while a calculation is running. After the restart the main controller will try to restore the projects based on the remaining files in the working directory.
  Show icon in tray will display the following icon in the task tray if enabled.
  
  
  Enabling this option on Windows operating systems also adds the administration panel to the autostart, so that it will be automatically loaded after every restart. This option is independent of the Main controller server start.
  Please note that this icon is shown in gray color only, as long as the server is not started. Double-clicking on the icon will open or hide the Main Controller’s administration panel.
  Clicking the Start Server button finally starts the Main Controller’s service.
  You can click on the View log tab to see the logging information which provides assistance for troubleshooting:
  

  
  Solver ServerThe Solver Server needs to be installed on every computer in the network that should be able to remotely run simulations. In contrast to the computer hosting the Main Controller, the dedicated Solver Server computers also need an installation of the Program Files component.
  The installation of the Solver Server is done by default with every installation of the CST STUDIO SUITE™.  You can access the Solver Server administration panel via the start menu.
  

  
  Here you need to specify the Server port number that will be used for communication between the solver modules and the Solver Server. Furthermore, a Working directory has to be specified where the currently simulated job’s data will be stored temporarily. It is highly recommended to use a local hard drive to avoid unnecessary network traffic. Make sure that sufficient disk space is available in order to hold the job’s data.
  You also need to specify the name or IP address of the CST Main Controller’s computer together with its TCP/IP Port address. Once started, the Solver Server will automatically connect to the Main Controller.
  You may also specify the Number of servers to run on the local computer. This number specifies the number of simultaneously executed solver runs on the local computer. In many cases, it makes sense to run as many servers on one computer as the computer has processors.
  If Automatic updates is enabled and the Main controller was updated to a newer version the Solver server and the solver executables are also updated via the DC network to keep the system synchronized.
  On Windows machines the postprocessing can be started also on the remote machine if Remote postprocessing is enabled.
  TIP:
  The Windows operation system has a known limitation in the so-called desktop heap memory, which e.g. allows only a certain number of opened windows application.
  The Desktop Heap memory is defined and can be increased in the registry editor in the following place:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems -> Windows
  This key "Windows" contains a very long string, which should be similar to the following lines
  %SystemRoot%\system32\csrss.exe
  ObjectDirectory=\Windows
  SharedSection=1024,3072,512   
  Windows=On
  SubSystemType=Windows
  ServerDll=basesrv,1
  ServerDll=winsrv:UserServerDllInitialization,3   
  ServerDll=winsrv:ConServerDllInitialization,2
  ProfileControl=Off MaxRequestThreads=16  
  In this long string the Desktop heap memory is defined under: "SharedSection=1024,3072,512" (third value is not always present).
  On a 32bit system we recommend to change the SharedSection values into:   SharedSection=1024,4096,2048
  On a 64bit system we recommend to change the SharedSection values into:   SharedSection=2048,20480,2048
  These values also depend on the number of started servers on the system.
  
  Clicking the Start Server button finally starts the Solver Server’s service.
  When enabling the Show icon in tray option the following icon will appear in the task tray:
  
  
  Please note that this icon will be displayed in gray color as long as the corresponding service has not been started. If a calculation is performed the icon changes the color to signal the active desktop user the calculation process.
  
  
  
  You can also use the context menu which is display if you right-click on the icon to start/stop the server and show or quit the administration panel.
  You can now switch to the View log page in order to get some information that will be valuable for troubleshooting purposes:
  

  
  Please note that once the Solver Server has started and has automatically connected to the Main Controller, it should appear in the Connected clients page in the Main Controller’s control panel:
  
  

  
  Here you can find information about the connected solver servers like ping, status and OS information. You can also enable or disable special solver server. Just click the Use check box to do so. Disabled Solver Servers are marked with a grey dot in front of the name. If you enable or disable Solver Servers the Apply button will be enabled. Push the button to apply the changes.
  
  When running a remote calculation you can switch to the Running jobs tab where an overview of the actual running jobs is displayed.
  
  

  
  Here you can find the status of the currently running jobs. By right-clicking on the entry a context menu will appear where you can kill the complete project. If the project is still running it will be aborted immediately and all results will be lost.
