Double precision

Accelerated Computing CUDA CUDA Programming and Performance

Hi all,

Does current generation gpu’s are capable of actual double precision computation?
if so - how ? using CUDA - double precision memory buffers/Textures?
What about current generation shaders (glsl/hlsl) ? double precision samplers/ Textures?

Thanks!

Only the global memory nothing else.

Yes, NVIDIA GPUs can do double precision calculation in CUDA code, and have had this capability for 3 generations now. GeForce GPUs are much slower at double precision calculation, so you will want a Tesla or Quadro card if this is important.
