November 2015 Results (2nd order)

Here are the results for the older, second order (operators.7pt.c) HPGMG-FV implementation. 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.
