![]() ![]() Note that AdditionalPaths only helps to find files when you For more information, see Set Up Datastore for Processing on Different Machines or Clusters. You use a datastore, use 'AlternateFileSystemRoots' instead to deal For example, if Z:\data on your local Windows ® machine is /network/data to your Linux ® cluster, then add the latter to 'AdditionalPaths'. 'AdditionalPaths' must be the paths as seen by the machines in Note that path representations can vary depending on the target machines. You can use 'AdditionalPaths' to access files in a shared file Workers look for files, such as code files, data files, or model files, in the correct 'AdditionalPaths' name-value pair argument helps ensure that ( cwd), platforms, or network file system access. The default search path might not be the same on the workers as it is on theĬlient the path difference could be the result of different current working folders 'AdditionalPaths' and a character vector, string array, or cell Specified as the comma-separated pair consisting of Paths to add to the MATLAB search path of the workers before the script or function executes, For example, you might want to control it if your cluster uses a different filesystem, and therefore the paths are different, such as when you submit from a Windows client machine to a Linux cluster. It can be useful to control the initial working folder in the workers. batch uses an additional worker to run the function itself.īy default, batch changes the initial working folder of the workers to the current folder of the MATLAB client. If your code uses a parallel pool, use the 'Pool' name-value pair argument to create a parallel pool with the number of workers that you specify. To reduce overhead in this example, divideData is defined in a file outside of this live script. You can do this by simply adding a function line at the beginning of your script. ![]() As a best practice, convert your script to a function file to avoid this communication overhead. If you have a large workspace, it impacts negatively the data transfer time. Note that if you send a script file using batch, MATLAB transfers all the workspace variables to the cluster, even if your script does not use them. Specify the expected number of output arguments and a cell array with inputs to the function. For an example of a custom function, see the supporting function divideData. Place your code inside a function and submit it as a batch job by using batch. ![]()
