Message 1496975 - Posted: 29 Mar 2014, 3:55:48 UTC

Finally upgraded to Win7 after Microsoft stopped updates for WinXP earlier this month. Installed Seti & MilkyWay on my 'new' PC, but I'm not sure how to get both processors massaging data like it used to be set up on my old PC. In fact, I'm not sure how or when my old PC decided to begin processing 2 work units at a time... it just happened one day. I DO have 2 processors setup in my 'computing preferences', but can't seem to convince this PC to quit slacking off.
Thanks for any tips or pointers would be appreciated.

Microsoft hasn't stopped updates for Windows XP yet. That comes next month.

How many tasks do you see in Task Manager?

Task Manager processes shows:
boinc.exe / boincmgr.exe / boinctray.exe
and currently it's showing ONLY a single milkyway_nbody running

What have you got 'On multiprocessors, use at most (Enforced by version 6.1+)' set to?

nbody is likely a multithreaded application, set to use all available cores.

(Milkyway do have a single-threaded version: what's the full text in the status column for the task in BOINC Manager, including anything in brackets?)

None of Steve's nbody tasks are labeled mt, and the stderr.txt of his completed tasks say:

<search_application> milkyway_nbody 1.40 Windows x86_64 double OpenMP, Crlibm </search_application>
Using OpenMP 1 max threads on a system with 2 processors

Claggy: My computing preference are
On multiprocessors, use at most/ 80% of the processors
Enforced by version 6.1+

as well as-
On multiprocessors, use at most/ 2 processors

Richard:

That seems to be your problem right there. BOINC will round down to the nearest whole core. So 80% of the processors on a dual-processor system would be 1 core.

I just noticed nothing is displayed (no .doc / .txt file) when I click on:
Read config files or
Read local prefs file
from the Advanced tab of Boinc Manager

Nothing 'visible' is supposed to be displayed with those options. When you select Read Config files or Read Local Prefs file, you are actually telling BOINC to re-parse and load app_config.xml, cc_config.xml and global_preferences_override.xml respectively. They are not links to documentation for BOINC.
