title: "register" keyword in CUDA
body: <p>I have a large program that uses all the registers I allocated per thread (64) and spills to local memory. I would like to be able to tell the compiler which variables should remain in registers at all cost, and which ones I don't really care about. Does the "register" C/C++ keyword work in nvcc? Is there a different mechanism perhaps?</p>
  
  <p>Thanks!</p>
