I downloaded the new cluster toolkit 3.2.2.
Little 128 node cluster with master node.
The install scipt installs the rpms onto the master node.
Then it is taking quite awhile to 'Analyze node configuration'
Watching it's progress: It's taken 46 minutes to process 23 nodes.
I'm guessing the installer is attempting to discern network topology, or if any compute nodes share the install directory.
Though, when prompted by the installer, I selected 'non-shared' install, i.e. /opt/intel is local on each compute node.
