I am running the exe now - is it playing a game ? I'm seeing almost no CPU usage

It should play at least a couple of times per hour; it is in a mini-tournament.
If not at all then something is wrong.
I checked it and is still running.

Yes it is running and displaying output, but it uses just one core.

Hmmm that is odd.

I do:

Code: Select all

        // thread count, threads per group, etc
        nCores = std::thread::hardware_concurrency();

        if (nCores == 0)
                nCores = (int)sysconf(_SC_NPROCESSORS_ONLN);

Part of the output is:

Info string: 8:1 workers
sending work to zero workers
0 workers replied in time

What that means is:
- it detected 8 cores
- it has no local workers configured

Local workers: you could e.g. setup a proxy queenbee to which multiple workers connect. Then you have only 1 qb talking to my server.
Less traffic (altough 1KB per move is not that much), more latency.

Looks perfectly ok!

OK, but the CPU doesn't get above about 16% across 8 cores, meaning the overall load is about 1 core only. Same situation on the other 6-cpu box.
