I have be using PETSc for many days. Recently I find one subroutine in PETSc is a little slow, It is an initialization subroutine to fill in the matrix elements:
I find that the total time to fill in the matrix data is even much longer than the iteration time to solve the system
How could this happen? Could I accelerate the time for filling in the data?
