Most computers are equipped with a
Graphics Processing Unit (GPU)
that handles their graphical output,
including the 3-D animated graphics used in computer games.
The computing power of GPUs has increased rapidly,
and they are now often much faster than
the computer's main processor, or CPU.
NVIDIA (a leading GPU manufacturer)
has developed a system called CUDA that uses GPUs for scientific computing.
With NVIDIA's assistance, we've developed a version of SETI@home
that runs on NVIDIA GPUs using CUDA.
This version runs from 2X to 10X faster than the CPU-only version.
We urge SETI@home participants to use it if possible.
Just follow these instructions:
(Note: CUDA apps are supported only on Windows and Linux;
Mac OS X support is coming soon.)
1) Check whether your computer has a CUDA-capable GPU
CUDA programs work on most newer NVIDIA GPUs.
To find out if your GPU is compatible:
Identify the model name of your GPU.
On Windows, right-click on your desktop, and select Properties / Settings / Advanced / Adapter.
Note the Adapter Type and Memory Size.
