One quick note. A couple of typos in last table in the 3rd two cpu column. Got careless as to which file I was looking at and had to re-enter a couple of the numbers. Plus the 4th 2 cpu run... Similar to the others, with some better, some worse, speedup is still remaining fairly constant overall. The new "aggregate" is simply the sum of the 2cpu times from one column, divided into the sum of the 1cpu column. This tends to weight the searches with the longer times more heavily, while the average counts all 24 positions equally... The data:pos 1cpu 2cpu 2cpu 2cpu 2cpu 1 153 89 (1.72) 88 (1.74) 90 (1.70) 89 (1.72) 2 139 90 (1.54) 90 (1.54) 90 (1.54) 90 (1.54) 3 130 82 (1.59) 87 (1.49) 87 (1.49) 82 (1.59) 4 176 100 (1.76) 99 (1.78) 100 (1.76) 99 (1.78) 5 147 95 (1.55) 99 (1.48) 87 (1.69) 95 (1.55) 6 135 77 (1.75) 77 (1.75) 78 (1.73) 77 (1.75) 7 92 50 (1.84) 50 (1.84) 50 (1.84) 50 (1.84) 8 149 104 (1.43) 89 (1.67) 79 (1.89) 103 (1.45) 9 80 60 (1.33) 62 (1.29) 60 (1.33) 50 (1.60) 10 155 82 (1.89) 76 (2.04) 75 (2.07) 81 (1.91) 11 142 80 (1.77) 80 (1.77) 82 (1.73) 82 (1.73) 12 105 76 (1.38) 76 (1.38) 76 (1.38) 75 (1.40) 13 149 105 (1.42) 105 (1.42) 87 (1.71) 107 (1.39) 14 147 104 (1.41) 87 (1.69) 74 (1.99) 93 (1.58) 15 150 86 (1.74) 86 (1.74) 86 (1.74) 86 (1.74) 16 159 73 (2.18) 72 (2.21) 72 (2.21) 99 (1.61) 17 158 97 (1.63) 97 (1.63) 77 (2.05) 107 (1.48) 18 85 42 (2.02) 41 (2.07) 42 (2.02) 40 (2.12) 19 125 61 (2.05) 63 (1.98) 73 (1.71) 61 (2.05) 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". Some are solid, some vary significantly... More of this tomorrow perhaps...
