add a table describing runs (from work colleague). i'll attempt to explain the table in next check in.

FLASH Performance Experiment Notes

WD_def problem

We generated a weak scaling curve (WD_weakscaling.pdf) on BG/P using data from 4416, 6144, 8192 processor runs.

"Updated numbers, all tests run with updated code, with Paramesh4dev:

Nblocks(ini) Nprocs t_evo tref max#blk/proc mem/proc[GiB]


110387 4416 573.8 32.5 29 .5 110387 8192 374.1 24.8 17 .5 154419 6144 609.8 47.5 29 .5 203443 8192 633.9 55.2 29 .5

Rows 1,3,4 constitute the weak scaling curve to be. Rows 1,2 test strong scaling."

t_evo is the total evolution time
