Thank you very much for your prompt reply.
Actually, I want to reorder MPIAIJ matrix using Parmetis. The reordering function needs the same information with the partitioning, that is "i" and "j".

Are you just redistributing the matrix? Or other data?

I need to directly get them and then use the function in Parmetis.
