If the perl script doesn't work for you (which it might), you might be able to write an expect script. Expect will wait for certain conditions before proceeding. That way, for example, the script can wait for "readyok" before sending "position ...", and wait for "bestmove ..." before sending "quit"

The UCI protocol says nothing about command line arguments. I am guessing you were using some engine-specific feature. Do you know which engine you were using? Also, it sounds really useful to have a standard "interface" for executing commands using command-line parameters. It would simplify certain...

The entire point of ASICs is that they are designed to do exactly 1 thing very well, unlike CPUs and GPUs which are very general-purpose.

BTW using CGI, if you set up your server correctly, you can get the basic auth username and password passed through CGI: https://httpd.apache.org/docs/trunk/mod/mod_authnz_fcgi.html . By default, it appears that the webserver attempts to perform auth for you. You can get the request method from REQU...

Wait, I think I am misunderstanding you. When you say "score", do you mean the static evaluation of the current position?

I haven't implemented null move pruning, but theoretically... Pruning when score == beta should only fail for the same case as pruning when score > beta -- when the side to move is in zugzwang. Pruning for score >= beta should be strictly better, unless there is some other bug with your null pruning...

I believe it should be:

What I currently have is a CGI 'server engine' that supports the following arguments on HTTP GET requests: A couple things to note: you should never use HTTP GET for requests which update the state of the server. The way the HTTP protocol works is that GET requests are designed to be cachable anywh...

I agree with Srdja. Also, dealing with plain text files will limit scalability after some point. And you pointed out that multiple processes will have to modify the same file at a time, which could introduce concurrency bugs. The simple solution (IMO) is to let a DB handle that complexity for you. I...

My engine GearHeart is around the strength of TSCP. It's supposed to be a reference implementation of a chess engine, with most of the same features as Vice, but written in a C++ style. It should build on linux, but you'll need boost and sparsehash libs (you should be able to apt-get them).
