Non-local values

[Farshid Mossaiby]

Hi all,

I know that this has been probably asked zilions of times, just to make sure, what is the way to go if a process needs some values from a vec/mat that is not local to that process? Is there any way? For example each process provides an array of global indices, and in a (of course collective) call, gets the related values from appropriate processes?

Thank you,
