What dose the CUDA SASS instruction "SAM" and "RAM" mean?

Hi, how to understand the function of the instruction “SAM” and “RAM” ?
These two instructions belong to control instrction catagory.
Thanks !

Sorry no idea and I don’t see them in the instruction set documentation:

I’m going to move your post over to the CUDA Forum (this one is for the NVHPC compilers), to see if you can get an answer there.
