array convol optimizationv slow now [message #67287]

Hi All,

I have an array of [2,100,000,000] corresponding to x, y and
100,000,000 particles. I need to render these particles as gasussian
spots at x, y locations

Currently, I run a for loop through each particle and render each
particle in this for loop; it takes forever.

I am thinking to create an array of zeroes. at each location where
there's particles, I increment the value by 1. Then use convol to draw
gaussian spot.

Any suggestion to implement this!

Thanks a lot!
