How do I choose grid and block dimensions for CUDA kernels?
... size can impact performance and suggest a common heuristic for its choice based on occupancy maximization. Without wanting to provide the criterion to choose the block size, it would be worth mentioning that CUDA 6.5 (now in Release Candidate version) includes several new runtime functions to aid i...
Difference between decimal, float and double in .NET?
...thing that makes 0.1 "better" than 0.10000001 is because human beings like base 10.

We've come up with what we think is a reasonable solution using macros, but was curious to know if people could think of cases where this might fail or if there is a better way to do this. Please note we are trying to...
