Looking forward to testing the new version.

Yes, I saw : thank you a lot Leto (and all the CEGT team) for all these games ! I hope the new version will behave correctly with the popcnt detection : please let me know if you encounter problems (or not !)...

I'm pleased to announce a new release of my UCI engine : Orion 0.2

This version includes notably an attempt to automatically detect and use 'popcnt' instruction if present on your CPU. In case of problem, this can be disabled by running "Orion.exe -no-popcnt".

Unfortunately I couldn't test it, it's crashing when the engine has to make its move. It loads up and as soon as it has to make its first move it crashes.

Yes, Graham (from CCRL) has a similar problem on a PC without popcnt instruction : I apologize and I'm very confused...

I fixed the problem and I am currently playing non regression tests. The patched version should be available tomorrow morning.

Does your CPU support popcnt instruction (maybe there is another problem, according to the Murphy's law ) ?

Thanks,

David

Graham only know to write one line of code, which is the following:

when someone present an engine. He is polite, our chap here.

I have two computers that do (FX-8300, and i3), and two that don't (core 2 duo mobile and Q9650). It was on the c2d machine that it crashed, and I'm sure it would too on my Q9650. I now tried it on my i3 and it worked, it opened up a dos box saying something about popcnt support=yes, then it closed and it worked. I'm certain it would work on my FX-8300 as well but I won't have access to it until tomorrow.

Usually what I've seen other authors do is they release several versions, a standard version and an SSE4.2 version, because a lot of people still haven't upgraded to a modern cpu.

Thanks Leto for your feedback. I found yesterday evening an old laptop with a Core 2 Duo (T5500) CPU : after reinstalling Windows 7, I reproduced the problem and fixed it (the bug was strange : I will post a specific topic).

A patched version will be available soon but for the moment, according to the Murphy's law (:)) :

Yes, if problems persist, I won't have the choice. But I found interesting to find how to provide only one executable for everyone... It's also a sort of challenge

Thanks Fern.

The patch is available for all users that encountered problems on hosts without 'popcnt' support. Simply re-download Orion v0.2 from here.

I hope everything will be ok now... Don't hesitate to report any new problems. Thanks !

wait my next engine, Moron 5.0...
