Hello,

Please anybody who is involved in development of the CPDN Application, have a look at Result-ID 5110074.

The story:

yesterday I upgraded my kernel, and wanted to give the binary nvidia driver another try. I wanted to check, whether I could view the Graphics of CPDN.

Just after I hit the \"Show Graphics\" button in boincmgr the Graphics showed up for about half a second, disappeared and an \"Computation error\" occured in just after that. After that i recognized, that the module failed to install, which might have caused the error. But IMHO showing the Graphics should not influence computation in such a way.

All those preciuos CPU-cycles :(

Please have a look at that Result and see the error message. And please keep me informed ;)

Thanks for your interest.

Greetings
SC

PS: If there is any info missing in this post please let me know. I\'ll see if I can get it ;)

The last set of messages suggest that BOINC caused the crash:

But there were errors in several palces before this, staring with:

The file conversion shouldn\'t result in a client error.
Most likely it was the display initialization.
Which isn\'t really done by the cpdn app.
Could you please provide detail of your graphics card.

Hi,

Thanks for the reply. So now there is a backup solution in place ;). Once a day there will be an update from now on. I am using backup-manager for that, and before starting the update the boinc client is stopped, the home-partition for the boinc client is then remounted readonly after waiting for 180 seconds (as I don\'t know yet how to tell when the app is really finished after requesting the shutdown). Please tell: Does the boinc client wait until the running app is definitely shutdown, or does it forward the request for shutdown and than immediately shuts down itself? Maybe a stupid question, but I want to do it right this time ;)
.
.
.
And sorry for wasting that much work. Some questions though:

What happens to WU\'s that finished with a client error. Are they ever being retransmitted to another client? Or are they gone and never computed again? It would be a pity if important data was never collected, because of a users fault.

Hi,

my graphics card is a GeForce3Ti200 AGP with 64MB of RAM.

But I want to add, that I was fiddeling around with my xorg.conf to find out, how to get the binary nvidia-driver to work again. I later recognized, that the nvidia module wasn\'t loaded but the nv-driver for X provided by Xorg. I had all config-parameters set up to start the nvidia module, but actually I forgot to change the name of the Display driver module to \"nvidia\" in the \"Device\"-Section of the xorg.conf. So the \"normal\" nv-module was loaded with a set of parameters tweaked according to nvidia\'s README:

Section \"Module\"
Load \"bitmap\"
Load \"dbe\"
Load \"ddc\"
#Load \"dri\"
#Load \"GLCore\"
Load \"evdev\"
Load \"extmod\"
Load \"freetype\"
Load \"glx\"
Load \"int10\"
Load \"record\"
Load \"type1\"
Load \"v4l\"
Load \"vbe\"
EndSection
.
.
.
Section \"Device\"
Identifier \"Nvidia GeForce3 Ti 200\"
Driver \"nv\"
VideoRam 65536
EndSection

At least I think the config looked like that, as the one I used for testing wasn\'t backed up too :/


Maybe that will help too.

Correction:

Failed wu\'s are marked for re-issue up to 4 times.
However, they may or may not be used again; there are millions of combinations to try.
