Need help to make Crafty work

[hgm]

For the record, after I type "go" and wait a couple of seconds and type "force" crafty stops the search instantly.

Did you test that instant response to 'force' on a Mac? It is conceivable that testing for pending input has some platform-dependent effects.

That being said, delaying the execution of a force command to when the thinking expires naturally is a behavior you will find in many engines. It is not even clear whether this is improper implementation of CECP; the specs are a bit vague in this respect. The description of the 'force' command doesn't say it should be executed instantly, and it is not clear whether the discussion about possible implementations in the I/O section is part of the specs or just friendly advice. For the protocol it should not matter how long execution of commands takes; this only affects timing. Obviously the 'move now' command ('?') becomes a no-op if the engine does not watch its input during thinking, but even then the 'response' is as expected: the engine will eventually print a move.

Note that 'force' and '?' can never be the same: '?' does not change the engine's idea of which color it is playing ('player state'), while 'force' will set it to 'play neither'. So after '?' + 'usermove' the engine would start thinking and moving again, (and it might ponder in between the '?' and 'usermove'), while after 'force' + 'usermove' it will remain idle.

Always printing a move after 'force' interrupts thinking is a valid implementation, and the GUI should always be prepared for handling such a move even if it wasn't, as the thinking might have terminated spontaneously between the 'force' was sent and when it arrived. In that case one should consider the move a result of the thinking, rather than a response to the 'force' command; 'force' should never result in a move when the engine is not thinking, not even when it interrupts a ponder search. (This is the same as in UCI, where 'stop' will always be answered with 'bestmove', and the GUI must decide whether it should discard the move or not.)

Yes, this was on my mac. But the way Crafty handles input is quite serial. IE a chunk of text is read, and everything up to the first new line character (or ; if I remember correctly) is executed. Then the next segment of the input, again up to the new line or ; is read and executed. I don't see any way any commands can be executed out of order. IE there are not multiple threads reading input and executing commands in parallel, purely serial in this area. I personally never liked the force command. I actually had one in Cray Blitz, but the idea was (a) the program made a move and announced it; (b) you could use force to make it play a different move. When I started working on the board implementation, much of the winboard protocol of today did not exist. For example, when continuing a game, all we had was the "edit" command which was clumsy. And make it easy for humans to trick programs into repetitions. When I raised this issue with Tim (Mann), he came up with the "force" stuff that I thought was ambiguous and awkward. But it worked and solved the problem I wanted addressed. Probably 75% of the protocol came from me working with Tim to address each and every issue I encounter when playing chess on ICS, ICC, FICS, etc... Always wished we had just started over with a clean slate...

I still get some difficulties to make Crafty works smoothly.

Crafty continues to puzzle me by some ambiguous messages. E.g., it doesn't like to set cores=1 by displaying an error.

I am not sure it is better if I follow Crafty or insist to set that (cores=1) since I think users have all rights to set up their software. Do you think cores=1 is typically accepted by other Winboard engines?

First I guess Crafty may show messages only for the above issues and it is not a serious problem. However, sometimes (not always) looking to logs as well as testing it manually I see Crafty stops for a while and may refuse to reply "ping".

Below it is a log when Crafty says "AlignedRemalloc() failed, not enough memory." and stop working. It is weird since all other engines including Crafty can play normally before and after that match. So far I did not reuse any engine for matching.

Note that I have seen those issues several times.

Any idea to solve that issue?

crafty will always play cores=1 unless you tell otherwise - but the error means nothing here - so it seems like you are building GUI that combines UCI and xboard?? or are you building an xBoard GUI that is using a UCI to xBoard adaptor. If you turn the crafty log, it will provide more information - crafty should not crash at all under xboard - something else is going on here.

I would run crafty in terminal mode first using your commands with the log on, also crafty requires an 'rc' file (on mac OS ".craftyrc"

- something like this:

I just ran a 10 game crafty vs crafty with the log turned on , no crashes, no flags, at the time control you used 40 move /6 seconds -

everything ran perfect - a new instance of crafty was started for each game automatically with xBoard.

logs attached

cores=1 is illegal so far as Crafty is concerned. cores=0 says to disable the SMP thread stuff completely. If it accepted cores=1 it would incur some overhead that gains nothing useful at all. Has always been that way. The ideal solution would probably be to parse the cores command and if it is <= 1, then set it to zero silently, which would get rid of the error (which hurts nothing by the way).

If you want to fix this, go to option.c and look for "cores". In that block of code, you will see "if (smp_max_threads == 1) {

Delete the two Print statements that follow, leaving only the "smp_max_threads = 0;" line. The error will be gone and it will still work as it should.

Thank Mike and Bob,

From Mike's game logs, I suspected my Crafty binary may cause the problem. Thus I have downloaded a new (actually it is three years old, not really new ) one from Mike's github - Crafty 25.2 for macOS.

- It (Mike's binary) still displays the error message when I set cores to 1
- I have run some tournaments for almost whole days, Crafty played over 100 fast games. It surprised me: none of them are crashed or timeout!!! It means I can use Crafty from now on with my interface.

Thanks. I am willing to fix Crafty. However, I am wondering why my compiled binary of Crafty cannot run smoothly. Not sure that is caused by my broken system or Crafty has a problem with new gcc. Anyone has ideas about this issue?

BTW, in my system, Crafty created too many log/game files. Is there any way to turn them off via command line or Winboard features/options? Thanks.

add the line "log off" to the file ".craftyrc" , place the hidden file in the same folder as crafty.rc

Note that 'cores=1' is not CECP, but that I accidentally wrote that earlier when I meant "feature smp=1". When an engine does not understand this feature, it does not support the CECP 'cores' commans to set the number of search threads, and the GUI is not supposed to send it.
