There are several output-controlling options - e.g., you could redirect the
output from each process to its own file or directory.
However, it makes little sense to me for someone to write convergence data into
a file and then parse it. Typically, convergence data results from all procs

Hi Mark
Back in the days I liked the mpirun/mpiexec *--tag-output *option.
Jeff: Does it still exist?
It may not prevent 100% the splitting of output lines,
but tagging the lines with the process rank helps.
You can grep the stdout log for the rank that you want,

release.
I think you're probably running into an issue that is just a fact of life.
Especially when there's a lot of output simultaneously from multiple MPI
processes (potentially on different nodes), the stdout/stderr
