Is this normal? I\'d hope that BOINC should use most of the processor when nothing else is going on. Is there a way to crank it up?

BOINC will use as much as possible, up to 100%.
You may have other programs running which are using the rest.
Check your preference settings to make sure that says 100%.
You may find something about it <a href="http://boinc-doc.net/boinc-wiki/index.php?title=Main_Page"> here</a> in the Wiki.

There are not many people using Macs, so there isn't much info available on them.

What is telling you it is only using LT 1% of the CPU? The way I check this to to go to my Applications/Utilities folder and start up Activity Monitor. You'll be able to see the CPU usage here for each process in your computer. You can also go to your account preferences on this web site and make sure your settings look like this:

Do work while computer is running on batteries?
(matters only for portable computers) yes
Do work while computer is in use? yes
Do work only between the hours of (no restriction)
Leave applications in memory while preempted?
(suspended applications will consume swap space if 'yes') yes
Switch between applications every
(recommended: 60 minutes) 60 minutes
Confirm before connecting to Internet?
(matters only if you use a modem) no
Disconnect when done?
(matters only if you use a modem) no
Connect to network about every .1 days
On multiprocessors, use at most 2 processors
Write to disk at most every 600 seconds

I'm also running Macs on various boinc projects, and when crunching CPDN, the computer just does about nothing. Checked that with Menumeter and a top command in a shell. No doubt : nothing happens.

Any CPDN boinc developper around here ?

Let me add some details :

On my 2CPU G5, when starting CPDN from boinc manager, 2 instances of hadsm3_4.1 appear, but no activity :

PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE
835 hadsm3_4.1 0.0% 0:00.18 1 11 33 96K 2.81M 1.15M 38.8M
834 hadsm3_4.1 0.0% 0:00.21 1 11 33 96K 2.81M 1.15M 38.8M

In the manager, eveything seems OK, 2 WU are declared 'running' but progress stay @ 0%, and no CPU time appears...

Does it sounds like a BIG bug, or am I missing something ?

hadsm3 is the CPDN control process. The actual work is done by hadsm3um, which should be spawned automatically.

Looking at your results I see that one has returned the error message:

dyld: hadsm3um_4.12_powerpc-apple-darwin can't open library: /opt/ibmcmp/lib/libxlsmp.A.dylib (No such file or directory, errno = 2)
