Good question! I think the answer is Yes, as long as the "change directory" operation is run in each of the nodes when you start. That means as part of an AUTOEXEC or the standard snippet of code that runs when you connect to a server. It's worth testing to make sure it does what you need. Also, as you know, since each grid node has its own file system, you would target a shared network file location for any output (data sets, other files) that you want to persist after the work is done.
