Hi reading about MatGetsubMatrices, that it must be called on all processors the same number of times. Does this mean all processors in PETSC_COMM_WORLD or on all processors that contain the Parent Matrix.
For example. If I am using four processors, but only rank=0 has a seq matrix A and it wants a seq subA on rank=0, do the other three processors need to make a call?
