Sudoku - validate errors

[trigggl]

I don't know if this is old news, but it seems like half the wu's for Sudoku are having validate errors. Windows or Linux makes no difference.

Have not crunched this in quite a while, so did not know this...

I figured out that all of my tasks that had validate errors, were those that had already previously had a validate error on some other computer. So, I went through one-by-one per host, located all the offenders and aborted them. No more validate errors and a lot more RAC is the result.

Oddly, my old processor that's over-clocked to 2.4 is getting better credit awarded than the processor running at the stock 3.06. Could it be that over-clocked hosts get preferential treatment on this project? Are credits awarded based on stock cpu freq despite what the cpu is running at?
