[petsc-users] Does flagging a matrix as symmetric improving performances?

[Edoardo alinovi]

Hi Berry,

Thank you for the hints. Actually, I am using MPIAIJ, does this mean I need
to change the matrix format?

Most of the time I am using CG + boomerAMG, do you think that using a sym
matrix can be any good for the performance?

Cheers
