thought i'd try 2x3x3 ... then this happened (hope next WU will use 18?) (EDIT: Yes, using 18 now)

Can you show a bit more from your log, so we can see what project this was? I had the same thing, and there are some projects with a maximum number of computing threads, which in these cases seems to be 9. These may be assigned to your machine even if you have advertised 18 cores, when no suitable other work units are available.

Here's what it looked like for me:

Code: Select all

14:50:35:WU00:FS00:Connecting to 129.32.209.203:8080
[...]
14:50:42:WU00:FS00:Received Unit: id:00 state:DOWNLOAD error:NO_ERROR project:16932 run:13 clone:53 gen:0 core:0xa8 unit:0x0000003500000000000042240000000d
[...]
14:51:17:WARNING:WU00:FS00:AS lowered CPUs from 12 to 9
14:51:17:WU00:FS00:Running FahCore: /usr/bin/FAHCoreWrapper /home/hopfgeist/FAH/cores/cores.foldingathome.org/lin/64bit-sse2/a8-0.0.9/Core_a8.fah/FahCore_a8 -dir 00 -suffix 01 -version 706 -lifeline 13604 -checkpoint 15 -np 9
I have a couple more, in at some cases lowering from 24 directly to 9, they are all from a certain range of projects, I have seen 16923, 16930, 16932, 16934, 17201.

Cheers,
HG.

P.S. I see you are running Client 7.6.13. Although I don't think this is related, you might consider upgrading to a more recent version.

Unfortunately I got distracted by some other thing so ended my test without saving the log
