Interesting ! This does almost what I need. Yes, adding a "%r" feature could be a convenient thing. Also, is it possible to append traces to an existing log ? Tried '-a_ksp_view ascii:a.log:append' without success and can't find the expected keys (to build the command line) in the doc (local solves are handled by each proc iteratively => need to append traces to previous ones at each iteration).
