My 2D Hydrodynamic GPU code is over an order of magnitude faster than CPU codes (its source is in my git repository). It is wasteful if I do not apply it to study some (astro-) physical problems. It turns out that, by introducing a simple -term, [...]

When working with LaTeX, it is recommended to start each sentence on a new line. The reasons can be found in Axel Brandenburg’s computing tips and this stack overflow page so I won’t repeat them here. However, as an emacs user, I always want emacs do the [...]

Reduction on GPUs

By On May 17, 2011 · Leave a Comment

I am recently interested in the properties of Bose-Einstein condensation in two-dimension hydrodynamic turbulence. Without the Ekman term (linear friction), the time to reach a saturated state is proportional to the Reynolds number, which can be very long. Therefore, I want to improve my GPU code to [...]
