Dell HPC Benchmarking (ccls.research.sfsu.edu)
For reasons of security, we don't post our benchmark results publically. However, in addition to research calculations, here are a few of our methods for estimating cluster peformance:
The Dell Cluster as a Render Farm
MPI-Povray 
is a computationally parallel version of the award-winning
POV-Ray 
ray-tracing rendering software. POV-Ray simulates how light would travel from one or more light sources, reflect off objects in a scene into one's eyes. As one might expect, this is a computationally expensive feat, and lends itself well as a high-performance cluster computing application.
High-Performance Linear Systems Package (HPL)
[[http://www.netlib.org/benchmark/hpl/][HPL] is a software package that solves a (random) dense linear system in double precision (64 bits) arithmetic on distributed-memory computers. It can thus be regarded as a portable as well as freely available implementation of the High Performance Computing Linpack Benchmark.
