Runtime error

Open francescoli opened this issue 10 years ago • 2 comments

Hi, Paul Is there any video card requirement of this project? I'm using a GT620 video card and get a runtime error after successfully compiling the 2.4.9_backport branch. using cuda-gdb, I get the log as:

Any idea to solve this? Best regards Michel

Yes, At the moment it requires cards with compute capability 3.0 or above because the kernels use warp shuffle intrinsics and bindless textures. I could write a version without the warp shuffles pretty easily, but I have been unable to get old style textures to work. If you could figure out how to use the old textures, I'd be happy to write the shuffle free version. I should note that without warp shuffles it will probably run at about half speed, since the data will need to be loaded twice.

Got it. No need to rewrite, and my new video card is on the way. I will have another try then. Thank you, Paul
