It is amazing to see such hard DIAMONDS coming out following 2 days of searching a pattern. I recall 1.5 years ago when I posted my first 9.9. it took much longer than that

adding pearls/diamonds has made it interesting
finally in this round I've become competitive
but only after adding 8x2.6Ghz to do the searching/se-rating

are you counting cores ... as in, e.g., running two applications on two-core machines

its a 16 cpu machine, each dual core, so 32 cores
no one else is on it at the moment
so half are searching for 17s (success rate decreased dramatically recently)
the the other half just conscripted to patterns searching today

this is probably old news for you, and you're likely using unix
but I just recently learned that with Windows XP on single dual-core CPU

one sudoku.exe application only uses about 50% of available CPU power
75% of one core and 25% of 2nd core; two applications uses 100% of both
