easy enough. Don't "give" it an amount of time to use and fix the depth based on that. Instead, start the search and stop when time runs out...

This is not a new idea. Same thing occurs in a cluster chess engine where you distribute the transposition across all nodes. Latency is high compared to local memory. There are several papers around on cluster chess engines. You might give 'em a whirl to see what has been done in the past. The bigge...

Someone recently wasted their time writing up 20 paragraphs showing how they could "exploit" Stockfish into crashing.... If you send a chess engine garbage, you should expect garbage. If you don't know it is garbage, then maybe a GUI should be doing it for you. The above has been affirmed many time...

I am not sure why your example fails. IE when the parent dies, the kernel should change the PPID to 1, which lets "init" take over as the parent, where it will absorb those SIGCHLD signals and wait() to get their status and dismiss 'em. Of course, you do have to make sure the processes terminate, ot...

The most elegant solution to this is to do the following: (1) I assume you use either fork() or to spawn new processes. Either works. (2) in the code that does the fork (the one where fork returns pid of child you need to catch the signal SIGCHLD. When a process terminates in unix/linux/etc, the O/S...

You might check out your compilers many alignment optimization options...

This is a bit confusing using normal terminology. "age" refers to the search that an entry is stored. IE it advances once for each real move played on the board. The idea is to let you recognize entries that come from the previous search (which might be great for the current search or completely use...

In 1969/1970 PL/1 was "the up and coming language" with bits of Algol, FORTRAN and COBOL included. And then in the 80's it was ADA. There is always going to be the next great language that turns out to be "not so great". C is 50 years old. That much history can't be completely wrong.

Probably would work, but you won't have a PV for the best move at that point. Would be sort of an odd circumstance as to how this might happen, however. There's a moderately good chance that the PV can be recreated by following the stored best move from the hash for as far as it goes, which optimal...
