How to maintain parallel processing in attribute wrangle

[DougStruthers]

My question is:  Can the following functionality be implemented with the node running in point mode?

Not sure this is possible but there may be a work around to keep it running in parallel?

I have dense geom (about a million or more points) at input 0

I have some points with 1 attribute "A" (a per point rotation value) at input 1

Using a for loop for each point at input 1, use its "A" value to rotate geom at input 0.

When geom at input 0 is rotated, use point at input 1 to shoot it at the rotated geom.

Add a point with the hitpoint coord, 

Create some attributes on the new point for distance, direction to hitpoint, etc.

I have spent several days, including implementing this with a foreach loops but that is way too slow.

Any suggestions appreciated.

Can you rotate (and reposition) those "some points" upfront? Instead of rotating the heavy geometry.

Then you could use the Ray Sop just once, for all the "some points" and just one collision heavy geometry.

Difficult to interpret exactly what you mean, example file?

Thanks for suggestions.  I am implementing Jiri's suggestion.  I think it sounds like the solution.
