No multi thread archiCAD?

Anonymous — Tue, 31 Oct 2006 01:34:23 GMT

Seems like AC10 only uses 1 of my four processors in my G5 Quad. Is this fixed for Intel Macs? Why isnt archicad able to use 4 processors?

archicad isn't a multi-processor aware application . . . and apparently re-writing it to be one is a huge job.

the lightworks rendering module is multi-processor aware, but the testing i did with it suggested that this aspect, too, only managed to use 2 processors at a time max in a quad . . .

I took a class on that recently.... it's a HUGE undertaking to make a program work with a multi-processor setup.

I know AC9 Lightworks ran all 4 processors on my Quad G5 but I have not tried it AC10.

I think the transition to multi-threading in Archicad will be slow, and gradual, but it will happen with time. Remember, Lightworks now works within Archicad and it's still multi-threaded. We will see that within other Archicad program modules eventually, as needed, and as prioritized within Graphisoft.

The issue is that the .pln file is a database, and you can't have multiple threads updating it simultaneously. Priorities and privileges must reign, or we'll have chaos. What I think is possible, though, is multiple threads running in the background updating background views/windows while you're working, this would give you less delays when you switch views.

it does not work that way.
Archicad has a core programming layer. An internal graphic engine.
That part has to be rewritten. This is not a part by part procedure.

Lightworks is an external program. It has nothing to do with archicad.
It may be multicore aware or not. The procedure goes [send file to renderer->get image]
