Computer grasshopper question loading and calculation time

[Mahdiyar]

…Modelling applications such as SolidWorks, 3D Studio Max and Rhino will use only one processor core for some modelling tasks. Some complex modelling calculations are linear and do not lend themselves well to multi-threading i.e. splitting the calculation between a number of processors. Rhino 6 and Grasshopper 1 are, however, more supportive of multi-threading than Rhino 5 and the Grasshopper Beta and we expect this situation to improve further as development continues… read more

Modeling has to be done ‘in order’. Consider the example of a box with filleted edges in a shaded display. The render mesh needed for the shaded display can’t be generated until after the edges of the box are filleted, and the fillets themselves can’t be made until after the box itself is created. First the box is made, then the edges are filleted, then the render mesh mesh created. You can’t put the box creation in one thread, the filleting in a second, and the mesh generation in a third and run all three processes at the same time.

A fast video card does not help Rhino calculate Booleans, generate meshes, at all. Rhino doesn’t use the GPU for any geometry calculation. What a good GPU does is lets you Zoom/Pan/Rotate the view more quickly.

V6 Feature: Multi-threaded GH Components

The latest WIP includes a new behavior in Grasshopper that we are experimenting with to improve performance; multithreaded component solving. The following four components have been modified to perform calculations using multiple threads. Contour Dash Pattern Divide Curve Boundary Surface We are decorating these components 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 s…
