Hello,
Is there a matrix version function of VecScatterCreateToAll?
I'm using preallocator for preallocation of global matrix.
Prior to using the preallocator, information related to allocation is
stored in the specific matrix, and this information must be viewed in all
mpi ranks.
For using

For example, before using preallocaotor, I made A matrix. (A matrix has
information about indices of global matrix)
And the code structures are as below.

I am not clear on what you said "this information must be viewed in all mpi
ranks." Even with preallocator, each rank only needs to insert entries it
knows (i.e., don't need to get all entries)
Maybe you could provide an example code for us to better understand what
you mean?
