Don't split if reduced depth is below min_split_depth It seems to increase SMP performances. To note that this patch goes in the opposite direction of "Active reparenting" where we try to reparent an idle slave as soon as possible. Instead here we prefer to keep it idle instead of splitting on a shallow / near the leaves node. After 11550 games on a QUAD (4 threads) at 15"+0.05 Mod vs Orig 1972 - 1752 - 7826 ELO +6 (+-3.6) No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
