Overview
Grasshopper for Rhino 6 provides multi-threaded solving in specific components. Benchmarks have shown that Grasshopper can be up to 20% faster when using multi-threaded components. Results may vary as there are only specific components that can compute in parallel.
The following components have been modified to perform calculations using multiple threads.
- Curve Plane Intersection
- Project Curve
- Pull Curve
- Split with Brep
- Shatter
- Split with Breps
- Trim with Brep
- Trim with Breps
- Area
- Area Moments
- Volume
- Volume Moments
- Brep Closest Point
- Mesh Plane Intersection
- Brep Line Intersection
- Brep Brep Intersection
- Brep Plane Intersection
- Curve Curve Intersection
- Curve Curves Intersection
- Point in Brep
- Point in Breps
- Curve Self-Intersection
- Contour
- Dash Pattern
- Divide Curve
- Boundary Surface
Multi-threaded components are decorated with small dots in the upper left corner to help you understand the component’s capabilities and current ‘mode’ of operation.
- No dots : the component does not currently support multi-threaded calculations
- One dot: the component does support multi-threaded calculations, but is currently calculating with a single thread (i.e. legacy mode)
- Two dots: the component does support multi-threaded calculations and is solving using multiple threads.
For components that support multi-threaded calculations, the feature can be enabled/disabled using the right click context menu on the component itself.
We continue to look for components that would be useful to have multi-threaded. Join the Multi-threaded Grasshopper component discussion to participate.
Creating you own multi-threaded components in Grasshopper
Custom multi-threaded components are also possible by programmer your own components in C# or Python. for details on this read the Making Task Capable Components in Grasshopper guide
