I was on revision 1081 and things seemed fine.

I just updated to 1083 and I get the right scaling for arachne and muzzle for the default scene.

What machine is this on and what is the scene you are rendering?

Do you know what version you were coming from?

Also keep in mind you may have pulled in changes from the SCIRun/Core libraries.

Before I updated with James's last commit, when I specified -np 2 I got roughly a 2x speed increase. Now, for some reason, I get a slight speed decrease. This seems to happen for all scenes -- the default manta scene as well as my isovolume work. Has anyone else noticed anything like this?
