Notes
|
||
|
|
(April 2009)
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
- Press 'h' for help screen. This shows keyboard cmds available.
|
||
|
|
|
||
|
|
- By default, GPU simulation is off.
|
||
|
|
When running the fluid_gpu.exe, press 'g' to start/stop GPU simulation.
|
||
|
|
|
||
|
|
- Disabling shadows in common_defs.h will greatly speed up the simulation
|
||
|
|
(You can also press 's' to render without shadows)
|
||
|
|
|
||
|
|
- As of April 2009, CUDA builds only under Visual Studio 2005, not VS 2008.
|
||
|
|
To enable the CUDA build in VS2005, set the BUILD_CUDA define in common_defs.h
|
||
|
|
Be sure this is turned off if you build with VS2008.
|
||
|
|
|
||
|
|
- The GPU integrator is not yet complete. Integration always takes place on the CPU, in both CPU and GPU modes. (As a result, this forces a bus transfer to and from the GPU per cycle. Once the integrator is finished, GPU simulation performance should increase significantly.)
|
||
|
|
|
||
|
|
- Occassionally, the GPU simulation with crash cuda, causing the screen to blink and particles to move randomly. This is believed to be due to a not-yet-found out of bounds condition.
