I’m seeing a lot of mysterious behavior with Nsight 4.6, 347.88 and CUDA 7.0 on Win7/x64.
My primary debug target is a headless Maxwell 750 Ti.
Setting breakpoints in certain locations will hang the kernel. The debugger never resumes control at the breakpoint but you can break/stop out of the debugger.
Some kernels don’t seem to be debuggable no matter where the breakpoint is set.
This is in a very mature 24x7x365 codebase that was debugging fine with 4.5, CUDA 7 RC and the previous driver.
I hate rolling back… any suggestions?
