But you will _never_ with any chess program run more processes than you have processors. And I do mean _never_.

I do not agree. This is very useful for testing.

Threads doesn't work, not all programs use threads I know you'd say that :) But processes and threads are basically the same thing. On Linux threads are created by the clone call which is a sort of fork except that all memory is (or can be) shared. Internally everything is managed by the scheduler....

I think it should definitely be Threads.

I often run several threads on 1 CPU for testing. Of course performance goes down but for testing that's ok.

The default value for Threads should be the number of CPUs.

I have my client (icsdrone-ng) send a "ping" command every minute.

I.e. an (illegal) command

ping_timestamp

That seems to overcome the 60 min idle time limit.

I have now included some sample code in the specification * pg_key.c: This little utility computes the PG key of a FEN. Note that it does ZERO error checking on the legality of the FEN and hence will segfault if something is wrong. * pg_show.c: This utility looks up a PG key in a PG book and prints ...

Say for instance as white, I only play 1. e4. Other possible moves such as 1. d4 or 1. c4, need to be in the book because I need to know how to respond to them as black, but I would never play them as white. Ok I understand. In PG you would set the weights of d4 and c4 equal to zero. In fact it see...

Once again a new version. There are no changes in the specs but one
of the test keys was wrong (a copying error).

I have now independently verified them.

I did not see mention of color support in the book spec. So with this format it is not possible to specify opening to be played only as white? I don't quite understand what you mean. The color is encoded in the position. Can you explain? If you add some of the ideas from this model to the polyglot ...

I have posted a new version as I had forgotten to indicate how castling moves are represented.
