A new version of BOINC is ready for public use. You can download it here. See the release notes and version history for details.

Hi all !
This is ONLY for Windows !!
Linux still to 7.2.42 recommended version ...

Sounds like an application error. Did they start using a new application?


Hi ! Could it be that these are applications for Kepler not for Fermi ?
How can I see ? This is a bunch of CUDA 31 so ....

I plan an update to Ubuntu 12.10 this w.e. . I'll see...

Hi ! I already posted this on GPUGRID forum : http://www.gpugrid.net/result.php?resultid=6086684

here I am : http://www.gpugrid.net/hosts_user.php?userid=57540

Since about 2 days, all WUs are failed as soon as they start if even they did with BOINC 7.0.39 Latest nvidia drivers.

This is the last error I've got (sorry this is in french) :

4) Message boards : Questions and problems : Missing CPU core ! (Message 45825)
Posted 27 Sep 2012 by jlhal

So answer the question:
what is shown in Tasks tab - Status column for one GPUGRID task:
Running (0.XX CPUs + 1.00 NVIDIA)

(what is the exact value for 0.XX)



Right now for 2 GPUGRID running tasks :

0,568 CPUs + 1 NVIDIA GPU (device 0)
0,568 CPUs + 1 NVIDIA GPU (device 1)

+ 6 cores running 6 active World Community Grid tasks (1 each)

ALL 8 cores are busy for crunching (75% max power set in preferences)!
So WCG using 6 cores I can reasonably conclude that 2 are used by GPUGRID !
If there was only 1 core used for both GPUs, what is the 8th core doing at 75% of its power ?

By your explanations I think that BOINC automatically free one CPU core for 2 GPUGRID tasks.
...
Look in Tasks tab - Status column:
- does it say for the 2 GPUGRID tasks:
Running (0.50 CPUs + 1.00 NVIDIA)
Running (0.50 CPUs + 1.00 NVIDIA)

BOINC will add 0.50 + 0.50 and automatically free one CPU core
(taking 1 core from what you allow total for BOINC use)

The values '0.50 CPUs + 1.00 NVIDIA' are supplied by the project.
If you see some change in that it is not caused by BOINC version but by GPUGRID - maybe new app?


My understanding is that BOINC should allocate 1 CPU for 1 GPU, 2 for 2, 3 for 3 etc...
This is what's happening still now. 2 cpus are allocated, 1 for each GPU.
The problem is, according to me, that it allocates 2 cpus but counts only 1 is allocated , thus saying that 7 are used as a max...

Post:

Why do you think that GPUGRID will occupy/use a CPU core?
Do you really have enough CPU tasks on-board to utilize all your CPU cores?



HI !
Sorry for the late response but I 've not been emailed about your answer...

Anyway, I have to give the following precisions , for my Windows system (the same applies to the Linux one with 6 cores total) :
My CPU is an AMD FX8150 with 8 cores.
My GPU is a GTX 590 : 2 GPUs
SWAN_SYNC is set to 0
I have enough WUs preloaded for work with WCG
If I want 6 cores for WCG ( 2 for GPUGRID), I used to set Max number of CPUs to (100/8)*6 = 75%
Now , to obtain 6 CPUs working for WCG, I have to set this to 87,5% , and Boinc tells me in the journal that I'm using a max of 7 CPUs which is correct according to 87,5% !
I just verified right now this : coming back to 75%, the number of active WCG tasks went down to 5 , instead of 6. Back again to 87,5 it went to 6 tasks active again .
GPUGRID uses actually:
0,491 of 1 CPU for GPU0
0,568 of 1 CPU for GPU1

If GPUGRID was sharing 1 CPU for 2 GPUs , I should have 7 tasks active for WCG
Looking at Windows task manager I can see that ALL CPUs are well busy .

Do you need more informations or are my explanations still not clear ?
What flags could be set in cc_config to help diagnose this ?
Regards and thanks for your time.

HI ! Did someone notice that on both Linux and Windows , since 7.0.34, 1 CPU is missing in the total count of active WUs?
For Windows I have 8 cores , 2 for GPUGRID (GTX590) and only 5 for WCG !
On Linux I have 6 cores, 2 for GPUGRID (GTX590) and only 3 for WCG !

On both OS the max nr of CPUs used is correct.

Great work !
If this CPU is capable, is a version for AMD Tegra 3 planned ? I would like to try it on my Acer A510 (Android 4 ICS)!
