Hi Chuck, Are able to exit cleanly?
What happens if you disable hyperthreading? Robert. On 2/7/07, Chuck Cole <[EMAIL PROTECTED]> wrote:
I tried the updated osgviewer.cpp and I get the same results – locks up when pressing 'm'. Again, I've been testing .txp databases although it doesn't seem to make a difference what type of model is being displayed. What's a little interesting is that Zach is getting a slightly different result in a similar configuration as mine (see items 6 and 7 in his list). With my Pentium 4 3.0GHz, hyperthreading on, Windows XP configuration, the viewer locks up on the first press of 'm'. I'll try and do some more debugging to see what I can find out. chuck ------------------------------ *From:* [EMAIL PROTECTED] [mailto: [EMAIL PROTECTED] *On Behalf Of *Robert Osfield *Sent:* Wednesday, February 07, 2007 4:17 PM *To:* osg users *Subject:* Re: [osg-users] CVS performance test Hi Zach, There is chance that its Windows threading issue, but more likely a general threading issue. Unfortuantely, I don't have enough cores to test CullThreadPerCameraDrawThreadPerContext, but even without enough cores I've seen a few instabilities with this model, its very new and not yet debug well. I've disabled the toggling to this threading model in osgviewer.cppand checked it in. Could you try a cvs update and see how you get on. Cheers, Robert.
