Short answer: Yes, at the moment a shared disk area among the front end and the nodes is required. Long answer: The preferred installation (see Server side installation instructions) assumes that some disks (the grid area, the cache directory and the runtimeenvironment scripts) are NFS mounted on both the frontend and the nodes. Not having NFS results in losing functionality like the cache or the RuntimeEnvironments, furthermore the job submission backend of the Grid Manager needs to be modified.
