eleeye_engine runs very slowly

[jeremy-list]

Binary package hint: gmchess

To replicate: set search depth to 14, start game, and make a move.

The computer opponent takes a very long time to move. Checking the system monitor shows that eleeye_engine is only using 28% of available CPU time at the most. Usually the waiting channel is hrtimer_nanosleep.
I find it fairly easy to beat the engine with search depth at 12 and would love the challenge of the greater search depth that could be made possible by using all the available CPU time.
I have tried fixing this bug myself but I couldn't find where sleep was being called

Hi,
I am the maintainer of this package, I believe there is a bug in gmchess prior to 0.29.3. You should install libeval-dev as well to make eleeye find libeval0, which is very useful for it to improve the strength.

You can add this PPA to upgrade to 0.29.3 (maintained by me):

Thanks for your report.

Mark as fixed because already solved in new release (natty). For users using older release, please use ppa:gmchess/ppa instead.

Have upgraded to the version of eleeye in https://launchpad.net/~gmchess/+archive/ppa for natty. Although it is playing better, it is still leaving the CPU idle and taking a long time to move

Subscribed lerosua to have a look.

A note, with 0.29.3 installed, you might don't need to set such a high search depth, :)
