Choosing the Shared temp-dir option means that temporary files created will be accessible to all execution nodes and the master server, without having to move them between machines.
For an external application to be executable in a grid environment, the Share temp-dir option must be chosen for the working directory.
For external applications that will be run on job nodes, one can choose either the Shared temp-dir or the Default temp-dir option. Here, the default temp-dir would not normally be an area shared between machines, and thus the choice of the Default temp-dir means that files will be moved between the master and job node(s).,
If you configure the Shared temp-dir for an external application, this area must:
- Be configured in the Import/Export directories area under the Main Configuration tab (see section 3.3).
- Be a shared directory, accessible to your all machines that will execute the external application.
