[petsc-users] flops performed on each processor

[Xiangdong]

simply replacing -log_summary with -log_view ::ascii_info_detail does not
produce anything. (Sams as -log_view ascii:filename:ascii_info_detail.)
Where does it dump the log? Is this the feature of new petsc? I am using
petsc-3.4.3.

Thanks.
