Answer 2

I would try using network paths instead of local paths for working directory, input, and output directories(\servername......). That has worked for me when running jobs on multiple nodes.

Answer 3

You have to setup network shares to run from all nodes. We did it so on our cluster. All users have their own directory on \<headnode>\users\<username>. Hope that helps.

Kind regards
