Owen,

HPC system requirements are pretty much 100% application-dependent.  Large
scale ABM simulations, like EpiSims require clusters with fast
interconnects, as Marcus indicated.  Other HPC apps have different
requirements.  E-Commerce needs large memory + lots of CPU horsepower for
database transaction processing, but not necessarily low-latency MPP
interconnect.

Other apps might have low-bandwith, high-latency behaviors that cloud-style
HPC could satisfy.

BTW, I got a case of the Willies looking at the NMCAC page.  The have a
pretty capable cluster, but the organization looks like it was patterned
after the worst of the bureaucracies that LANL and the State of New Mexico
have demonstrated.  Look at

for an example of what I mean.
