Increase CPU Usage VW

Recommended Posts

Hi guys,

 

Using VW on a complex Site Model, each Update takes more than a minute. I tried to increase the priority to High but it didn't had major impact. Any suggestions?

Hi

I have found that increasing the simplification tollerance of sitemodifiers helps improving the speed without decresing the visual. My document is set up in meters and having the simplification tolerans to 0,1 is ok

Thanks for your reply. I've done that. I was only wondering if we can increase the CPU usage by the program itself.

Your CPU is already used at 100%, but only on one core. The calculations for the terrain model were not or maybe can't be parallelized, they cannot therefore be distributed over several cores. For example, with a 4-core CPU, Windows shows a load of 25% (100%/4 cores), although the full single-core performance is used. Not all calculations can be parallelized. For example, everything that has to do with rendering can be parallelized well while Geometry calculations are difficult to parallelize because the result of the calculations depends on the previous calculations.

So that would be a massive increase on productivity, to have these kind of calculation parallelized. Wishlist material, what do you thing? Worth a post on the correspondent forum?

This is not worth a wish list entry. The developers are aware of the potential and write new code in a way that makes the best use of the hardware. Nevertheless, it will never be possible to parallelize all processes, because for many it is mathematically impossible.
