I’m getting immediate “CUDA error: Launch failed in cuCtxSynchronize()” on default cube on buildbot builds starting from r57284. CPU rendering works.
System is linux Mint14 64bit on 2x AMD Athlon™ 64 X2 Dual Core Processor 3800+, 5081MB RAM, GeForce GTX 560 2Gb. Nvidia driver is 304.88.
Will appreciate any suggestions on what i’m possibly missing or should do in order to get Cycles working on GPU again.
there has been a big reported for it here

Thanks, ng-material!
Oh, now they come… Googled yday, but it slipped by me; got results just from the last year.
Fixed:

Thanks, mib2berlin, for a good news!
One can just admire such operativeness and confidence of devs!
Unfortunately even after this http://lists.blender.org/pipermail/bf-blender-cvs/2013-June/056474.html patch for r57319 cycles GPU rendering fails with the same symptoms here on r57327.

Hi eppo, do you have a SM_21 video card, this mean Compute Capability 2.1?
You may find your card here:
Brecht disable something in r57360, should work again.
Cheers, mib.
Hi, mib2berlin,
GeForce GTX 560, it shouldn’t have any capability problems yet afaik?
NV list simply ignores this and mentions Ti and mobile M only; Geeks say it’s 2.1 which i believe i have seen somewhere on NV site too.
Guess i have to wait again when it appears on builder. Not really tried to build after reinstall OS.
Cheers.
I have still problems with my 2.1 card after rebuild, can´t get it to work.
Think brecht fix this next days, will report here.
Cheers
Hi eppo, brecht fix it.

Yep, downloaded, yesterday’s build (have no number atm, r5738x iirc) works with GPU.
Thanks all!
