Technical question: Memory management.

Question to Ondra:

Can You explain how memory managed between cores of CPU by Corona. Let’s say that we have two PC’s with different number of cores (4 core i7 and 2xXeon E5-2650 with total 16 cores) and scene that needs 16Gb of RAM to render. Do we need to increase memory x4 times on 2xXeon PC to compensate number of cores or we need exactly the same 16Gb to render this scene?

Thank You in advance.

you need about 2 MB ram more per core. So… you need always the same RAM

Great! Thank You!

And how much cores Corona supports? I heard that V-Ray can render at 60 cores maximum. Does Corona can utilize more than that?

I havent tried it, but there are no obvious limits. Just as many cores as your windows machine can handle. There is the memory bottleneck though, so the scaling wont be perfect.
