I need both right and left vectors for use in a SLEPc SVD decomposition; it is my understanding that the correct layout is obtained with MatCreateVecs and that only the layout for the right vector is created with DMCreateGlobalVector.

Do you have a non-square matrix? If so, is the left vector associated with a different DM?

Or I might be wrong and there is actually no difference! If so I will use DMCreateGlobalVector without any problem

If the system is square, DMCreateGlobalVector should be correct.
