I had two windows open matching moves/times for run 3 and another open watching run 4. I got the wrong window a couple of times. I will check all 4 again today now that it is not running. And if you want to see the raw data to check yourself, feel free to yell and I'll put the logs somewhere they can be accessed. Take _all_ of this with a grain of salt until I/you/we check the numbers. I did these as they ran last night which makes it easy to screw up at 11pm or later... :) I found the errors I found by going back thru the logs, but I really need to make one more careful pass today (or someone does) to be sure that I didn't "cross over" on others... > >>20 160 112 (1.43) 117 (1.37) 109 (1.47) 107 (1.50) >>21 156 73 (2.14) 62 (2.52) 103 (1.51) 53 (2.94) >>22 77 60 (1.28) 73 (1.05) 41 (1.88) 42 (1.83) >>23 134 93 (1.44) 95 (1.41) 97 (1.38) 97 (1.38) >>24 131 84 (1.56) 82 (1.60) 115 (1.14) 105 (1.25) >> average speedup-> (1.66) (1.69) (1.71) (1.70) >>aggregate speedup-> (1.64) (1.66) (1.68) (1.64) >> >> >>This gives a pretty good idea of what I meant by "variability".
