[petsc-users] PETSc crashes when different rank sets row, col and A values using MatCreateSeqAIJWithArrays

[Maruthi NH]

Hi all,

I have a row, col, and A values in CSR format; let's say rank 0 has 200
unknowns and rank 1 has 100 unknowns. If I use MatCreateSeqAIJWithArrays to
create a Matrix, it crashes. However, if each rank has an equal number of
unknowns, it works fine. Please let me know how to proceed
