Hi All,
When testing Crafty on a position using long time controls, I've noticed that
the node counter reaches 4-5 billion, but never goes beyond this number, but
decreases giving a false nps. As the search does not appear to be affected
by this behaviour, It is not really a problem.
Is this a limitation of 32 bit computers, Crafty, or the C language, not sure,
I'd be interested to know the answer.
Here is Craftys output on the same position, the first is 333 min, the second
is 500 min
time=333:20 cpu=99% mat=-1 n=4160976338 fh=10% nps=208044
ext-> checks=209585241 recaps=13647126 pawns=4243489 1rep=19302187
thrt:1356639
predicted=0 nodes=4160976338 evals=827478374
endgame tablebase-> probes done=0 successful=0
time=500:00 cpu=99% mat=-1 n=1837858478 fh=8% nps=61261
