Multiple Instances of Rhino - Grasshopper

Hi,

If I have a multiple cores on my computer as with many desktops nowadays, is it beneficial to run multiple instances of Grasshopper if I am trying to run through a long animation sequence.

For example, if I have 200 iterations/variations of a geometry to explore, would it be faster to have two instances of GH with one running the geometry iteration from 1 to 100 and the other from 101 to 200?

Right now, things run sequentially and it's ok speed wise but like everything else would be better faster.

Thanks.

I'd say only if you have enough memory. Yes, if you have the cores to do it, you can run GH on two separate instances. But GH will eat through a ton of memory, especially if your rendering an animation. That might alone cause Rhino/GH to crash.

Thanks Damien,

For my knowledge, what in your opinion is enough memory? The general impression is more is always better but I guess what is a good starting point for trying out these multiple instance runs?

First of all, are you running on a 64 bit machine? If you aren't, then I wouldn't do it. If you are on a 64 bit machine, then the answer would be 3.8 * the number of instances you'd want to run. So if you only have 4gbs of memory, then I'd stick to just one instance. If you have 6-8gbs then you can run two. If you've got a quad core and 10-12 gbs of memory than try 3.
