Description

System Information

Windows 7 , Quadro 4000 + Geforce GTX 690 (Driver 335.25)

Blender Version
Broken: 2.70 aee3018, b4d259f
Worked: 2.70 release 19e627c

Short description of error

When using Branched Path Tracing on GPU I get an error message and glitches in the viewport:

CUDA error: Not found in cuModuleGetFunction(&cuPathTrace, cuModule, "kernel_cuda_branched_path_trace")
CUDA error: Invalid context in cuCtxDestroy(cuContext)

Does not start rendering when all GPUs ("Geforce GTX690 (2x) + Quadro 4000") are enabled as compute device or only one GTX 690 is chosen.
But does start rendering with only using the Quadro 4000.

Similar to T39355 I get an empty image when pressing F12 (or only the Quadro renders its tiles) and the error message in the viewport.

Branched Path is currently disabled on sm_30 cards, due to compile failure after Multilight Sampling changes.

@Thomas Dinges (dingto), if it's disabled on purpose i don't think it's a bug.Just consider a known TODO and close?

Thomas Dinges (dingto) renamed this task from Branched Path disabled on sm_30 cards to Branched Path disabled on GPU.Apr 11 2014, 12:10 AM

It's a regression that should be fixed for 2.71, so I will leave it open.
