[petsc-users] parallel interpolation?

[Gideon Simpson]

Suppose I have data in Vec x and Vec y, and I want to interpolate this onto Vec xx, storing the values in Vec yy.  All vectors have the same layout.  The problem is that, for example, some of the values in xx on processor 0 may need the values of x and y on processor 1, and so on.  Aside from just using sequential vectors, so that everything is local, is there a reasonable way to make this computation?
