History
Perft(10) took 85 hours to calculate for 4 computers (two of them not working
24/7). The current project is calculating on perft(11). I'll post statistics
here when the project is getting somewhere.
Perft(11) started 2003-12-11 12:49:47 and finnished 2003-12-19 05:54:52 taking
over a week to calculate. Several computers worked on the calculation, I guess
that over 50 computers contributed to the result with many of them working
24/7. The problem had a slow start and slow end so in practice the problem
could have probably been completed in 5 days when running on full speed.
