BOINC will delete all the cuda stuff if it finds you don't have a cuda device. This normally happens if you uninstalll the old drivers and BOINC starts up before you have managed to install the new one. Its happened to me once, how I remember to tell it not to run at startup before I do the driver upgrades.

To fix it shut BOINC down and put the two dll's back into your projects\setiathome folder and the vlar kill .exe file back. Start it up and check the messages tab to see if there are any [error] messages about missing files.

Its supposedly addressed in 6.10.13 so it won't delete them, but it will abort all the cuda workunits still (if you have any that is).

With the new version of Boinc (6.10.13) you will lose only the wu.

Interesting. Just about to start up on a mixed ATI / Nvidia rig. Fingers crossed

I tried switching over to the 2.3 CUDA DLLs and it works fine but after a few WUs on the next comminication with the servers, it seems boinc insists on replacing the files with 'known' versions:
11/17/2009 3:32:35 PM    SETI@home    [error] File cudart.dll has wrong size: expected 192512, got 285696

It then stops processing WUs on the CUDA device

What am I missing to keep BOINC from downgrading cuda 2.3 dlls?

You need to be running "anonymous platform" - i.e. with an app_info.xml file - to stop BOINC checking the file sizes.

But most people who visit here are doing that anyway - they come here for the optimised applications, which rely on the same mechanism. If you're running optimised applications, you can just drop the DLLs in without thinking about it.

ah thanks !
Funny thing I missed that because a app_info.xml.bak is already there certainly from when the CUDA acceleration was still in development but I must have removed it when it was added in the normal builds.

Silly me
