[petsc-users] vec norm for local portion of a vector

[Xiangdong]

Hello everyone,

I have a global dmda vector vg. On each processor, if I want to know the
norm of local portion of vg, which function should I call?

So far I am thinking of using DMDAVecGetArray and then write a loop to
compute the norm of this local array.

Is there a simple function available to call? like
*vg->ops->norm_local(vg,NORM_2, &normlocal)?

Thanks.

Best,
Xiangdong
