Basically cluster_info only gets added to each node by vcld if there
is an image with subimages defined.

An HPC environment is typically using a parallel batch processing job
scheduler, like LSF (Load Sharing Facility), or MOAB for commercial
schedulers, open-src schedulers Condor, Maui, Torque.
Here is a link for overviews:
http://hpc-opinion.blogspot.com/2011/07/job-schedulers-overview.html
So you may want to check out each of those related sites for guides,
etc.

We use LSF here at NCSU with ~850 nodes.

As far as clusters within VCL, one could really build anything, but
what we've seen the most are researchers building hadoop clusters, a
distributed LAMP stack for a class, or SAS BI environment.

Hope this info helps.
