Hi Dean,

You may want to look at the links in my Slurm Wiki page.  Both the 
official Slurm documentation and other resources are listed.  I think 
most of your requirements and questions are described in these pages.

My Wiki gives detailed deployment information for a CentOS 7 cluster, 
but much of this information should be relevant for Ubuntu as well.

/Ole
