title: 128 bit integer on cuda?
body: <p>I just managed to install my cuda SDK under Linux Ubuntu 10.04. My graphic card is an NVIDIA geForce GT 425M, and I'd like to use it for some heavy computational problem.
  What I wonder is: is there any way to use some unsigned 128 bit int var? When using gcc to run my program on the CPU, I was using the __uint128_t type, but using it with cuda doesn't seem to work.
  Is there anything I can do to have 128 bit integers on cuda?</p>
