Most computers are equipped with a
Graphics Processing Unit (GPU)
which 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 5X to 10X faster than the CPU-only version.
We urge SETI@home participants to use it if possible.
Just follow these instructions:
1) Check whether your computer has a CUDA-capable GPU
The CUDA version of SETI@home works on most newer NVIDIA GPUs.
To find out if your GPU is compatible:
Identify the model name of your GPU.
On Windows, click on My Computer / Properties / Hardware / Device Manager,
and open Display Adapters.
This will show the model name.
