CRI_XCBC/README.md

-Simple playbooks to install OpenHPC version 1.0 using Ansible. 
-
-See the doc/README.md for a tutorial on using these scripts in a VirtualBox environment.
-
-The Ansible layout is fairly simple, using a series of roles for different parts of the installation process. 
-
-This repo will get you to the point of a working slurm installation across your cluster. It does not 
-currently provide any scientific software or user management options! 
-
-The basic usage is to set up the master node with the initial 3 roles (pre\_ohpc,ohpc\_install,ohpc\_config)
-and use the rest to build node images, and deploy the actual nodes (these use Warewulf as a provisioner by default). 
-
-Trigger the roles individually via tags, like:
-
-```
-ansible-playbook -t pre_ohpc -i inventory/headnode headnode.yml
-```
-
-None of these Ansible roles actually touch the compute nodes directly - at most, they build a new vnfs image and
-trigger a reboot. 
-
-A more detailed description is available in the /doc folder.
