What does LOP.AND.NZ do?

(4) I didn’t dump SASS code with cuobjdump since the tool using JIT compiler (apparently the tool owner also wanted to protect it, even nvprof couldn’t run the app). I had to use cuda-gdb to get these SASS code. is it a good way to extract sass? or it can cause missing some line of code.

I may be misunderstanding what you’re saying here, but is this any use?

nvrtc + cuobjdump/nvdisasm

i can easily export CUDA and PTX when using nvrtc (i.e. the inputs and outputs of the nvrtc compilation), but i can’t seem to figure out a nice way to get the .cubin and/or view the disassembly for nvrtc-compiled functions after loading them with cuModuleLoadDataEx(). i can see the SASS using nvvp, but that seems a bit slow/cumbersome. i’d guess maybe the debugger could work similarly, but i didn’t try it. i can also use ptxas on the .ptx emitted from nvrtc: ptxas out.ptx -arch sm_52 -o out.c…
