[petsc-users] Weird behavior for log_summary

[Michele Rosso]

Hi Barry,

I accidentally found out what triggers the problem with log_summary.
If I specify log_summary from command line, it works as expected. If
instead I open and load an options file with  -log_summary in it,
the output is incomplete.
I am actually concerned about using options files now because this weird
behavior could affect the correct loading of other options as well.
