Intro: All tests done with Shear15, ~¼ way through simulation. I am assuming that the other runs will scale similarly. Astrobear was built with hypre library 2.9.0 without global partition.

Method: In global.data, changed number of frames and restart frame by factor of 10. So final frame went from 200 to 2000, and restart frame was changed from chombo00050.hdf to chombo00500.hdf. Running this simulation then produces frames with dt = 1/10th of original frame, which I then multiply run time by 10 to get an estimate of the run time per frame (see below).

Nodes	Start time	Frame times	Average run time (not including first frame)	Avg. time to write to file	Frames/hr
32	3:09	3:43, 4:15, 4:49	33 min/ .1 frame	1.9 min	.19
128	3:09	3:29, 3:43, 3:57, 4:12	14.3 min/ .1 frame	3.7 min	.55
256	3:14	3:29, 3:42, 3:55, 4:09	13.3 min/ .1 frame	6.8 min	.83
512	5:17	5:34, 5:47, 6:00, 6.13	13 min/ .1 frame	9.4 min	1.3
