Right now, for the first 8 cpu test run, here's what's happened to this point: position 1 Nxh6 is found in 1:06... position 2 Rxc5 is found in 8:31... position 3 Nxg5 not found in 20 minutes... position 4 Nxe6 found in 11:35 position 5 e5 not found in 20 minutes... position 6 axb5 not found in 20 minutes... Position 7 Rxd8 found in 12:45 position 8 Bxh7 not found in 20:00 from this point forward, I only have 4 processor results, the first 8cpu run has not yet completed. I'll give the 4 cpu results from here on and then update this later. position 9 Ng5 not found in 20:00 (it chooses Nxh6 here) position 10 Rxf7 found in 1:02 positoin 11 Rxh6 found in 0:17 (17 seconds) Total (so far, 6 correct, 5 wrong. Doubt this will change after the 8cpu test completes, but we'll see...
