[petsc-users] ghost size of a ghosted vector

2013-09-20 Thread Mohammad Mirzadeh 
Hi guys,

Is there any function that would return the ghost (or ghost+local
preferably) size of a ghosted vector? VecGetSize returns the total
global size and VecGetLocalSize returns only the local part.

I need this size for a error-checking guard i'm adding in my code.

Thanks,
Mohammad

  You need to call VecGhostGetLocalForm()  and call VecGetSize() on that. Don't 
worry, its cost is only the function calls.
