I'm actively developing Monarch once again and I've nearly completed a substantial re-write of many fundamental routines (removing color dependency and assembly code). One thing I'd like to do is to make the code more portable across platforms - especially Linux and Mac. The main obstacle to this is the multi threaded code in Monarch. I have the engine calculate in one thread and I 'listen' for input in another. I realize that I could avoid this complication and do everything in a single thread (like Fruit and Glaurung) but eventually I'd like to make Monarch multi-threaded so I decided to create a separate thread for the engine from day one. Can anyone advise me on the best way to do this?
Here are the multi-threading routines I use under Windows.
- Code: Select all
thread_handle = (HANDLE)_beginthreadex( NULL, 0, &engine_loop, NULL, 0, &threadID );
aPriority = GetThreadPriority(GetCurrentThread());
SetThreadPriority(thread_handle, aPriority);
_endthreadex(0);
WaitForSingleObject(thread_handle, INFINITE);
Are there any (free) cross-platform libraries that I can use to replace these routines? Which one would be the best fit for this purpose?
At the same time I'd also like to add a routine to measure and display at the end of the search the CPU time utilized by Monarch (like Shredder and Fruit). Is this easy? Any pointers?
All help appreciated?
Steve
