Made SU use Multiple Processors!

HA! Got you.
Yes, you can make SU use multiple processors.
That is, if you are willing to run it on Linux (I'm using Ubuntu 8.04) and WINE 1.0.
Exactly why this is true I don't know, but I am getting very nice performance in most respects even though Fast Feedback doesn't work (due to issues with OpenGL in Linux).
I can't quite get the screencapture to hit the moment of maximum shared burden, but look closely at the graph.

Thats pretty cool, but howd you do it? wine running on 2 cores and pretending to only be one?

I didn't do anything besides the general Registry tweaks necessary to run SU on WINE. But it is showing on all four processors. All four will really spike if I load up a large model, turn on shadows, and do some heavy-duty camera rotations. And they spike at different rates, as well...one processor will begin ramping up and the others will after a tiny interval suddenly begin to react.
I only happened to notice because I was looking for something else on the System Monitor and saw the resource graph.

It may be running on different CPUs, but not at the same time.

No, assuming you trust the GNOME resource graph (and I have no reason not to do so), it does show concurrent CPU burden. They do move at the same time, and if I switch to percentages the numbers change at the same time, although the burden is not shared equally.
This is consistent with what I see with modeling programs that do use multiple processors.
You're the Google person...you explain it.

He he
...That's really funny.I can't imagine us all switching to Linux to run sketchup through Wine emulation (I know it's not just emulation
).Let's hope SU 7 will do that for windows and Mac...and pppplease also a 64 bit version.
-
I spoke with John Bacus today at the AIA convention about this...he insists that SketchUp as currently written can't run on multiple processors for quite valid technical reasons. "It must be WINE doing something," he told me.
But WINE doesn't show under the system processes as CPU use changes. SU does.

Damn Lewis I saw this post heading and thought YESSSSSS! Linux-- NOOOo!
I was so hoping! Well I must say I hope google will be bold enough to rewrite the engine one day soon to allow it to run over multipro and also to hanle better high poly counts. SU has so much potential that I feel is limited so much at present given the inability with high poly count!
FINGERS CROSSED!!!!

Where's that petition we should sign?
'multicore/64bit/high poly NOW' -
Petition away, but I don't think its in the cards quite yet, given my talk with John. Might as well ask for NURBS, while you're at it.
The Linux mystery here is amusing, but in any case multiple processors are no panacea for overly-complex modeling and too many polygons.
Hey Richard! Why don't I ever see you posting here?

Hey Lewis
Mate I've really only just joined this forum, the PPB is pretty much home for my SU fix as it covers a broader range of design topics not limited to SU!
I dropped in for the first time the other week from a link on the PPB and have decided to register and hang around a bit!
Must say I always find it funny how every forum I visit I get Richard as my username!! always a surprise really, make me feel important as if it's reserved - or is it simply no one wants to get called "Dick"?
