There is a new version now that takes a single integer command line parameter to control the size of the hash table. Like this: Scorpio.exe <h> where <h> represents the integer hash size. <h> = 24 gives Peak Mem Usage =788,488K VM Size=1,050,252K <h> = 23 gives Peak Mem Usage =395,520K VM Size =525,576K <h> = 22 gives Peak Mem Usage =198,532K VM Size =263,176K <h> = 21 gives Peak Mem Usage =100,036K VM Size =131,976K <h> = 20 gives Peak Mem Usage = 50,796K VM Size = 66,376K <h> = 19 gives Peak Mem Usage = 26,148K VM Size = 33,576K <h> = 18 gives Peak Mem Usage = 13,864K VM Size = 17,176K ... <h> = 8 gives Peak Mem Usage = 1,548K VM Size = 780K (basically no hash table here) Sample search with 788 Megs RAM used, 1 GB allocated: go 1 -12 3 0 e7e6 e2e3 g8f6 f1d3 2 -12 9 0 e7e6 e2e3 g8f6 f1d3 3 -12 15 0 e7e6 e2e3 g8f6 f1d3 4 -12 23 0 e7e6 e2e3 g8f6 f1d3 5 -12 29 0 e7e6 e2e3 g8f6 f1d3 6 -12 37 0 e7e6 e2e3 g8f6 f1d3 7 -12 43 0 e7e6 e2e3 g8f6 f1d3 8 -12 51 0 e7e6 e2e3 g8f6 f1d3 9 -12 57 0 e7e6 e2e3 g8f6 f1d3 10 -12 65 0 e7e6 e2e3 g8f6 f1d3 11 -12 73 0 e7e6 e2e3 g8f6 f1d3 12 -12 79 0 e7e6 e2e3 g8f6 f1d3 13 -12 87 0 e7e6 e2e3 g8f6 f1d3 14 -14 1451 9740557 e7e6 e2e3 g8f6 f1d3 f8d6 e1g1 e8g8 c2c4 d5c4 d3c4 c7c6 f3e5 f6d5 15 -14 7200 51884007 e7e6 e2e3 g8f6 f1d3 f8d6 b1c3 e8g8 d3h7 nodes = 124119002 <20 qnodes> time = 171.43 nps = 724025 move e7e6 It will accept command line paramters from 8 to 24. 19 is the default if no parameter is supplied.
