[petsc-users] Sparse matrix vector multiplication performance

[Bernardo Rocha]

Hi everyone,

I´m wondering if it is possible to measure the CPU time of the sparse matrix
vector multiplications within a iterative solver such as the CG in PETSc?

I´ve been reading the manual, but it seems that the options -log_summary and
similar ones only track the convergence behaviour. So, how one could check
the performance of matrix vector multiplications?

Thanks in advance,
Bernardo M. R.
