How can I tell boinc to use all 24 cores?

No, the first box is a HP DL980 G5. This box is a Dell R610. I actually have 2 other Dell servers along with an HP ML370 and a Precision 690. All are server class HW.
I collect old gear which is DE-commissioned or upgraded, so I have tonnes of old stuff. Ive been selling some on eBay and Craigslist, but these are still one I haven't' sold yet.

I ran a 'find' command on /var/lib as well as my working dir, and I can't locate either filename.

Message 61696 - Posted: 19 Apr 2015, 13:36:42 UTC - in response to Message 61687.  

Under the /var/lib directory, there is only 1 dir called 'boinc', which is empty. There is no /var/lib/boinc-client directory.

[root@dell1 ~]# ls -lRA /var/lib/boinc*
/var/lib/boinc:
total 0
[root@dell1 ~]#

Im running boinc-client command from the root directory, and ran a search on all files in the root tree, and couldn't find the cc_config.xml or the global_prefs_override.xml files. At startup, the boinc_client sais it's using defaults because cc_config.xml is not found. Does this mean I should manually create the file using the contents you posted?

So, go to Seti@Home, if need be log in, then go to Your Account->Global (computing) preferences->edit them, set "Use at most 100% of the CPUs", save changes to the web preferences (Update preferences button at the bottom of the page), and update BOINC, probably through BOINCCMD.

Message 61699 - Posted: 19 Apr 2015, 14:13:24 UTC - in response to Message 61697.  

The 2 files you listed are not present in any part of the boinc tree. So, I may have to create them as you suggest. Can I use the excerpt from the post above to do that or is there some better method to create the files using the tools?

When I went to computing preferences, they are set to 100% by default already.
PS, im trying to get this working with the milkyway project first, then when I figure out how to do this, I may expand back to Seti as well.

Also, the SW keeps saying there is a newer version available, but when I try the URL, it only shows windows versions, not Linux versions.

Anyhnow, where can I find a more up-to-date Linux software? The Boinc website only lists Windows clients.

The website only shows Windows versions because there was a severe problem with wxWidgets 3.0 and a lot of Linux distributions. Therefore it's better to get the BOINC from repository and update with that.

The BOINC from Berkeley installs by default in the home directory (~/BOINC/).

When I went to computing preferences, they are set to 100% by default already.

Computing preferences can be found at the local level (if you're running with BOINC Manager), or at the project web site. It's unclear to me which computing preferences you now speak of. If the local ones, these will override the ones from the project.

PS, im trying to get this working with the milkyway project first, then when I figure out how to do this, I may expand back to Seti as well.

Computing preferences set through the project web sites are global. This means that you set them on one project's web site and they'll migrate to the other projects when BOINC contacts those projects. So it's not necessary to set them first on Milkyway, then on Seti.

Besides, the excerpt I posted came from your own log, showing that you were using the preferences from Seti, set on the 17th of April, on the location/venue: none (or ---). Always check that you're working in the correct preferences, that of none, home, work or school, and that the computer's location is set to that same location.
