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. In contrast, for a setup with CLC execution nodes that chooses the Default temp-dir setting, where such a directory is usually not shared between machines, files will be moved between the master and job node. The Default temp-dir setting will not work for any setup where the CLC Grid Worker will be used to submit jobs to a local grid.

If you work on a single server, then the Shared temp-dir setting can be used to specify a non-default area for temporary files.

If you work on a master-execution node setup, whether it be grid nodes or CLC execution nodes, the Shared temp-dir must be chosen, and this area must:
