For the #39, it took the 1060 6GB card exactly 44 seconds to find the key. Start to finish = 44 seconds, with 1 card. Grid size of 3072x512.
sp, is 44 seconds good on an old 1060 card?
No it is slow. should run under 100ms. You can retrieve the precalculated keys from
https://privatekeys.pw/ . Since the answer to the puzzle is already known and can be precalculated.
Back to the speed of my bitcrack implementation.
puzzle 39: 2^39 = 549 755 813 888 possible combinations
with a speed of 400 000 000 (400MKeys)
#38: 274 877 906 944 / 400 000 000 = 1374 seconds (around 12minutes)
#39: 549 755 813 888 / 400 000 000 = 1374 seconds (around 23minutes)
You would expect the program to spend 12-23 minutes. The hashes used to find the solution is printed in the miner window and can easily be verfied. Bitcrack sp-mod is working. I see that my fanclub is present already. I welcome you all. Go crack some keys.
