I have some code that I have been using for a while under cuda 3.1 and previous versions. After upgrading to 3.2, I can still compile, but now get an “unspecified launch failure” from my kernels.
I naturally went through the documentations and took a look at my kernels, but I can’t see anything incorrect (not surprising since the kernels have been in use for a while already). I am not using the Driver API.
Does anyone have any suggestions for what to look out for here? What changed in 3.2 that might be breaking my code?
fyi: I’m using a multi-Tesla c2050 system with ubuntu 10.04. I have the same problems on a different system with a GTX285.
