What You Need To Know<br />
FP64 instructions will be slower than FP32<br />
It takes more than just wider data paths to implement<br />
double precision<br />
For best performance, use FP64 judiciously<br />
Analyze your computations<br />
Use FP64 only for precision/range-sensitive computations<br />
Use FP32 for computations that are accurate and robust<br />
with 32-bit floating point<br />
<strong>CUDA</strong> compiler supports mixed usage of float and<br />
double<br />
Supported since <strong>CUDA</strong> 1.0<br />
