Suddenly my i7 x980 is working only 10 cores of 12. My prefs are:
On multiprocessors, use at most 100 % of the processors
Use at most 100 percent of CPU time
On multiprocessors, use at most 24 processors
I use Vista 32bit and latest Nvidia frivers. Anyone else saw that? I test also the 6.10.57 but same thing. Now I am back at 6.10.56. The funny thing is that I didn’t change anything.

Maybe you just run out of work for the CPU

Do you have any
SETI@home Enhanced v6.03
tasks left on your computer? (only 6.03 can be done by the CPU)

To see if you have any CPU workunits to crunch
in Tasks tab sort by Application column.
(make sure you Show all tasks - not just Show active tasks)

Yes i have only....1200 tasks SETI@home Enhanced v6.03. All tasks are visible.:-)

No, you have none

You are talking about this computer:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=5344008

All In progress tasks for computer 5344008
http://setiathome.berkeley.edu/results.php?hostid=5344008&offset=0&show_names=1&state=1
...........
http://setiathome.berkeley.edu/results.php?hostid=5344008&offset=1700&show_names=1&state=1

are only CUDA tasks (1700+ of them - I browsed all 85 pages)

Maybe this thread have clues about the problem:
Have work but only runing 7 tasks not 8?

Yes. the thread you send me help alot. I find out that when i Snooze Gpu all cores come alive. But now... what is this mean?

---

It means SETI is using all of one of your cores to support your GPUs. In BilBg's post he linked to a thread that is talking about this problem and a possible solution.

Seems that if you install
Lunatics' Unified Installer
http://setiathome.berkeley.edu/forum_thread.php?id=54288&nowrap=true#994550

the problem goes away.


Use CPU-Z to find the capabilities of your CPU
http://www.cpuid.com/softwares/cpu-z.html
(Download links at the right)

Select SSSE3 or SSE4.x app/setting in the installer.
Select CUDA 2.3 DLLs for faster GPU calculation.


You also will be able to use
ReSchedule 1.9
http://setiathome.berkeley.edu/forum_thread.php?id=59291

to move the tasks as you wish between CPU <--> GPU

So with new ‘’feature’’ Seti guys are punishing all the users with ‘’big’’cpus?
Because as I read at BilBg's post, he have the same problem, and if we do not use the Lunatics' Unified Installer and continue to use the default installer then we will never use all the cores of our cpus.
And perryjay what did you mean by ‘’SETI is using all of one of your cores to support your GPUs’’. Before that why seti could support it and now is not.
My other i7 965 is working the cores perfectly.

Tim,
I'm not all that techie but something that has been done on the server side while trying to fix the problem with the new Fermi cards has caused the % used by the CPU to increase. Apparently it is not effecting all CPUs but enough to be annoying. Give the guys time to work out what all is going wrong and get things going again. Hopefully that will be today.

Ok my friend.Thanks in advance. I will wait and see what will happen. :-)

... My other i7 965 is working the cores perfectly.

Your Computer with CPU:
Intel(R) Core(TM) i7 CPU 965 @ 3.20GHz
have 2 GPUs
[2] NVIDIA GeForce GT 240 (986MB)

Your Computer with CPU:
Intel(R) Core(TM) i7 CPU X 980 @ 3.33GHz
have 3 GPUs
[3] NVIDIA GeForce GTX 285 (1009MB)

So if the standard SETI CUDA app "thinks" it needs e.g. 0.40 (40%) of a CPU core to support feeding of 1 GPU with data you have:

For 2 GPUs
2 * 0.40 = 0.80 (80%) of a CPU core is reserved for feeding of 2 GPUs with data

For 3 GPUs
3 * 0.40 = 1.20 (120%) = more than one CPU core --> so 1 + 0.2 CPU cores are reserved for feeding of 3 GPUs with data


Obviously recently standard SETI CUDA app overestimates the need for CPU feeding support.


What do you see (in BOINC Manager - Tasks tab) on the two above mentioned Computers
about the CPU usage of any running CUDA task
(it shows as e.g. "Running (0.40 CPUs, 1 CUDA)" or "Running (0.40 CPUs + 1.00 NVIDIA GPUs)" for newer BOINC)







( I borrowed the image from this post (I have no CUDA host):

)

BilBg, The example you are showing, I bet is running optimized. If you look at it again it is showing running 0.04 cpus,1 cuda

So?

The picture (one year old) is only to illustrate where to look to find the numbers
and then post this numbers here (X.xx CPU + Y.yy GPU).

I say "e.g. 0.40 (40%) CPU" - there is NO correlation between my example of 0.40 and the 0.04 on the picture.

I don't know what it is really so I ask people which have CUDA to post the real numbers.
