40000 Fluid Particles in Grasshopper with FlexHopper, FlexCLI and NVidia Flex

This rough preview shows the functionality for fluid particle emittance, self collision and force fields in Grasshopper using the plugin FlexHopper (to be released soon). Particles can be grouped, assigned different properties and identified later for color indexing.
FlexHopper is built on top of FlexCLI. FlexCLI is built on of NVidia Flex.

Hi Friedrich,
I did this with a Dell Precision M4800.
i7-4800MQ @ 2.7GHz, 16GB RAM
The GPU is an NVidia Quadro K2100M

At the end when all 40000 particles are out it runs at about 5 - 8 FPS. Not amazingly fast. The main bottleneck is not solver update but bringing everything in the Rhino viewport. Solver update and the rest of the GH canvas run in parallel, so the slower one of the two dictates the resulting FPS. I'm assuming a faster CPU and high frequency RAM will speed up things quite a bit. I'll test that soon.
