Perfect, thanks Paranoid. Janzert also recommended a wrapper, and it's nice to have one written out for me!

I notice that badger is running parallel... you're an impressively fast programmer doublep!

On my new test set (where most positions are tested at around blitz speed), I get a speedup due to parallelization of 1.77. |

And now that I have access to quad-core, this ends up giving a speedup of 2.52, not quite such a big jump, but handy nonetheless.

The bot developers will definitely have to make their programs multi-threaded to take advantage of future hardware. It's getting difficult for the chip makers to squeeze more cycles per second and they are having to use multiple cores to continue providing more performance. By 2002 the chip makers had already reached the 3GHz mark, but have not yet hit 4Ghz.

Thanks  In my "defense", I kept parallellization in mind from the start (since the start was just around the New Year --- not so long ago). So, when I finally got to it (February 22nd, according to VCS logs), I only had to add proper locking to the reader. Everything else was already prepared, e.g. board was an object, not a global structure, etc.
