X4 Ray Tracing - Optimal CPU

[Ian Pellant]

Thanks Doug,

I had forgotten to check the Ray Optimization on the Xeon. It was turned off... so turned it on an ran the tests again.

The results from the HP Workstation with Xeon processor:

***************************
Ray Trace Opimisations Off
Single session
Xeon 2.53GHz 12:56

2 simultaneous sessions
Xeon 2.53GHz 12:54
Xeon 2.53GHz 12:54

4 simultaneous sessions
Xeon 2.53GHz 24:48
Xeon 2.53GHz 25:48
Xeon 2.53GHz 24:48
Xeon 2.53GHz 24:54

***************************
Ray Trace Opimisations On
Single session
Xeon 2.53GHz 6:08

2 simultaneous sessions
Xeon 2.53GHz 12:50
Xeon 2.53GHz 12:37

Indications are that Ray Trace Optimizations are effective with a single session. Simultaneous sessions drop back to double time.

X2 Send to Layout introduced a lot of artifacts compared to CA 10. I had logged a sample plan with CA Support - typical problem was inner wall faces in external wall corners appearing in the Layout, but were not seen in the plan vector view. This has mostly been fixed in X4. (Artifacts still occur - am trying to isolate them to log for you). Increase in process time is related to reduction of redundant overlapping lines - which simplifies manual clean up... sort of... Ideally the aim is to have WYSIWYG between plan vector view and what is sent to Layout.

Cheers.
