Hi all,

is it possible to autokill VLAR WUs with this Linux application? My system is very laggy with these long Work Units...  :(

Thanks for info,

Autokill unfortunately no. You can do it with a script or manually (make a search for <true_angle_range>0.01 or 0.00 and delete or abort them).

I realize that the app_info.xml files are hints, but is there a reason for the MB file to differ from the MB+AP file?

Should the version_num, avg_ncpus, and max_ncpus match between the MB+AP app_info.xml and MB app_info.xml files in setiathome-CUDA-6.08.i686.tar.bz2?  Same for setiathome-CUDA-6.08.x86_64.tar.bz2?

The MB+AP app_info.xml has version_num of 607 while the MB app_info.xml has version_num of 608.

The version 603 MB+AP avg_ncpus, and max_ncpus are set to 1.0000 while the MB avg_ncpus, and max_ncpus are set to 0.040000.

My CPU is running on 2GHz (Athlon X2 3800+), GK is 8600 GT on default clocks, openSUSE 11.1 64-bit, here are some results:

[...]

CPU utilization is almost 100% for SETI
I see pretty much the same on my system for an AthlonXP 6400+ and 8600GT GPU (256 MB VRAM).

Is the CPU doing a busy-wait poll of the GPU? Or why the high CPU utilisation?

As an experiment I'm keeping the CPU priority down to nice 19 (instead of the default 10) to see if there is any slowdown for the CUDA processing. However, that only reduces the CPU load to between 75% and 90% for a core.

Is there any profiling that we can run to see what it is doing with the CPU time?

Happy crunchin',

45mins -> 56-59mins...


Sooo... The slowdown looks to be roughly proportionate to the lower proportion of CPU used...

Are the nVidia Windows drivers so very much more efficient than their compiles for Linux?

Or are there very many frequent busy-waits for many small GPU steps?

I tried the MB only version of setiathome-CUDA-6.08.i686.tar.bz2 and got the GaussFit_kernel errors that smurf mentioned earlier in Reply #7 on: 21 Jan 2009, 05:53:48 pm after about 14 minutes or processing.

It has an Nvidia 8800 GTS 640MB.  The GPU core temp is usually 68C, but went to 80C when processing a CUDA workunit.  There was a single cpu process of setiathome running at 100%.

Would it help to use a newer version of boinc than 6.4.5?

Fedora 9, nvidia-graphics180.22-kmdl-2.6.27.12-78.2.8.fc9-180.22-106.fc9.i686 from atrpms, boinc-client-6.4.5-2.20081217svn.fc9.i386 from Fedora, with the latest Nvidia cudatoolkit_2.1_linux32_fedora9.run, for this computer - http://setiathome.berkeley.edu/show_host_detail.php?hostid=4131779

Here is an example taskid http://setiathome.berkeley.edu/result.php?resultid=1154715237

I tried removing the cuda 2.1 libs and using the cudalibs (2.0?) that were in setiathome-CUDA-6.08.i686.tar.bz2, but got the same GaussFit_kernel errors.

This was in a different workunit's slots/0/stderr.txt before it was uploaded:

I have been trying to get the SETI MB CUDA client running and ever work unit so far immediately hits a computation error as soon as it trys to crunch.

Have any of you run into this problem and/or have any suggestions?

'Tis working fine here and for the same revision for the nVidia drivers.

Kernel 2.6.18 is from a while ago now... It could well be that Crunch3r has used a much more recent kernel and a more recent version of gcc for his compiles.

Can you try a more recent kernel/distro?

I'm using Mandriva 2.6.27.7-server-1mnb.

Good luck,

I have a GeForce 8800 GT. Whats wrong here ?  :(


Now I updated to 180.22. But same situation. The card is not overclocked and temperature is 62 C. There are two types of cases:
- small WUs with a time to completion of ~7 min are running fine without any errors and granted credit is the same as claimed credit (14-15)
- big WUs with a time to completion of ~25 min have the gausfit error message and the granted credit is smaller than the claimed credit (claimed ~50, granted ~40)


I have exactly the same situation.
Video card is 8600 GT 256 MB, NVIDIA 180.29 driver.
Exactly the same uncountable error messages in stderr out, the same clamed/granted credits.
