max number of cpu cores

[alemanda]

Hi,
I recently updated my system to a dual xeon 14 cores. So Totally I have 28 cores.
When I launch a rendering I see that not all the 28 cores work together ... it seems that only 14 or 16 work.
Is there a limit in the number of cores used by Archicad?

Why is there no ArchiCAD/CineRender Benchmark model ? - so we can do some testing.
I have a new big dog computer now and I want to see how it actually compares.

Might be a fun idea. It would just need to be an PLA with included materials and objects, and we all could use it.

I have mostly used cinebench, from Maxon, the company behind cinerender. I think it's rendering motor is based on Cinema 4D R15, and ArchiCAD uses a more recent motor nowadays. Still, it has given quite reliable results comparing different machines - at least according to my observations.

OpenGL bench is not so good in this particular software, according to what I have read elsewhere.

I've got an ~800 figure with my ancient (but upgraded) Mac Pro 2009 now. You might want to give it a try.

Thanks. For testing with Maxwell I use this https://www.maxwellrender.com/benchwell/benchmarks/v4

One comparison test I can make for my self is to render a scene in CineRender, and then and because I have the Maxwell plug-in I then select Maxwell as the rendering engine and compare those results. I will be using GPU or CPU with Maxwell and I can see what difference that makes. Even that is not really a good test because I don't think it is possible to set up the rendering engines to do exactly the same thing. Also some card configurations will be better for one rendering engine than the other. Very difficult to compare apples to oranges.

This is why we need lots of tests so people can improve their settings to find what it optimal for their unique hardware/software set ups.

My biggest problem is optimizing the card for use with ArchiCAD. The NVIDIA set up gives a brief description about what the settings mean but I don't know if they are relative to ArchiCAD.
