Loading opening book and tablebases (xboard vs uci)

Post by pedrox » Sun Oct 15, 2017 10:55 am

xboard:
--------

Until recently my engine had only the xboard protocol. When the engine receives the xboard command the first thing it does:

printf("feature done=0\n");

This gives the time needed to initialize all kinds of things, I can read the configuration file or the command line for different options and then I can create and allocate memory to the hash table, load opening book and for example load gaviota tablebases, even I can load 6 mem scorpio bitbases.

After receiving the protover command I finish with:

printf("feature done=1\n");

I have no problems with this and with any GUI with xboard protocol.


uci:
----

When I read the uci protocol, I thought I understood that isready and readyok could be the equivalent. The protocol recommends that the GUI send the engine the isready command to give the engine time to load for example tablebases.

So I have used these 2 commands in the uci protocol to do the same thing that with the feature done command in the xboard protocol. But I have some problems with this:

- On cutechess, I have problems loading the gaviota tablebases when they are first started, it seems that the gui considers that the time has been exceeded and the game is not started, however once the tablebases are cached the rest of games are played smoothly. Bigger is the problem if I want to load 6 mem of scorpio bitbases, again the problem is the first time they start, then in cache the rest of games go well.

cutechess GUI allows changing the response time to the isready command?

- In Arena there is no loading problem for tablebases or bitbases, even if it is the first time and they are not cached. However I find another problem is that Arena does not send the command isready when the user changes engine options and therefore my engine then does not know that you have to make those changes until the engine is restarted.

This isready and readyok seems dependent on the GUI. Are there any alternatives?

You shouldn't load them unless the GUI sends the relevant UCI option, and certainly not automatically as part of the engine startup procedure.

And isready is not there to tell the engine something has changed, it is there for the GUI to check whether the engine is responsive.

The engine should change configuration things when the relevant setoption command for some engine parameter has been processed without waiting for isready.

It can make a lot of sense to wait for isready, because otherwise the order that options are set may be important.

For example, if the hash table is allocated before the use of large pages is indicated, the allocation has to be redone. That makes little sense.

Or if NUMA is being used, allocation may have to be redone if the number of threads or the subset of nodes to be used is changed.

In Cfish, I delay the processing of such settings to the moment isready or the first "go" command is received.

Show the log, with cutechess-cli use -debug option and redirect output to a file with >log.deb, then examine the log.

If GUI has sent isready to the engine, you are guaranteed that the GUI will wait for the readyok.

Code: Select all

* isready
	this is used to synchronize the engine with the GUI. When the GUI has sent a command or
	multiple commands that can take some time to complete,
	this command can be used to wait for the engine to be ready again or
	to ping the engine to find out if it is still alive.
	E.g. this should be sent after setting the path to the tablebases as this can take some time.
	This command is also required once before the engine is asked to do any search
	to wait for the engine to finish initializing.
	This command must always be answered with "readyok" and can be sent also when the engine is calculating
	in which case the engine should also immediately answer with "readyok" without stopping the search.

It makes sense to do this at engine startup, because UCI specs say that 'isready' is mandatory there. There is no guarantee 'isready' will be sent at any later time, however. So the engine must immediately respond to setoption command when not in the startup phase. Waiting for 'go' is inadvisable, as that is probably the moment your clock starts running in the GUI.

That is the price the user will have to pay for changing such options halfway a game :-)

I used to do this before, but I had a problem.

The engine can use scorpio bitbases, in these bitbases the user could change 3 options: path, cache size and load type.

If I receive an option to change the cache size I would have to download the bitbases and reload with the desired cache. If the user changes the load type or path also then I might have to do that process 3 times and then, which also gave me some problem like for example in chessGUI.

Maybe there is a possibility to wait to receive all the options and delay it to do all the configuration once and not use isready, but it would be more complicated and I do not see how either.

So you could process the delayed options the next time you receive one of "isready" or "go" and perhaps also "ucinewgame".

If the processing/loading takes long, then obviously delaying it until a "go" command has the considerable disadvantage that the processing is done while the clock is running, but if costly options are being changed while the game is being played there seems to be a problem anyway...

In the end, I guess this shows yet another shortcoming of the UCI protocol.

And one important thing is that the problem only occurs on the first load attempt, then it seems like the bitbases are in memory and load much faster.
