191.07 support?

<< < (2/2)

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  ::)
