Hi,

I'm currently calling DMDAVecGet(Restore)Array on a subset of 
processors. It seems to work correctly. So why does documentation say 
they are collective on Vec? Are they really? Unlike VecNorm, for 
example, it's not really clear why DMDAVecGetArray should be collective.

Am I still on a safe side, or I'm seriously violating something that's 
not immediately obvious.

Thanks,
Anton
