November 2014 Results (2nd Order)

Here are the older, second order (operators.7pt.c) HPGMG-FV results as presented at the Supercomputing 2014 BoF. Each machine was allowed to use any amount of memory per node. Unfortuantely, due to scheduling and allocation limitations, some machines only evaluated a single per-node problem size. Similarly, 'Fraction of System' represents what fraction of the system was available for benchmarking.  In order to reproduce these results, users should use the Chebyshev smoother (-DUSE_CHEBY or --fv-smoother=cheby) and modify finite-volume/source/local.mk to use operators.7pt.c.  However, submission for new ranking must use the approach described for the fourth order.
