title: Integer calculations on GPU
body: <p>For my work it's particularly interesting to do integer calculations, which obviously are not what GPUs were made for. My question is: Do modern GPUs support efficient integer operations? I realize this should be easy to figure out for myself, but I find conflicting answers (for example <a href="http://www.golubev.com/about_cpu_and_gpu_2_en.htm" rel="noreferrer">yes</a> vs <a href="http://www.gpgpu.org/w/index.php/FAQ#Which_number_formats_do_GPUs_provide.3F" rel="noreferrer">no</a>), so I thought it best to ask.</p>
  
  <p>Also, are there any libraries/techniques for arbitrary precision integers on GPUs?</p>
