Folks,

One of the questions that came up during the teleconference
last Tuesday was, "how can we use reporter.php to display
e.g., the performance of different BTLs"? At the time there
was little to cover that use case, but now there's
something.

If you type a regular expression into the Command text
field, the first pattern that matches the expression is
captured and will show up in the Summary table. Thus, you
can type e.g., "tcp|openib" into the Command field and there
will be a Command column differentiating the rows by
displaying the occurrence of the pattern "tcp" and "openib"
in the mpirun command.

Go here for an example:
http://www.open-mpi.org/~emallove/mtt/reporter.php?do_redir=65

Note: In addition to the Command field, all *large* fields
have this behavior, and can be identified in reporter.php as
*not* having an adjacent Show/Hide menu. (They are "Stdout",
"Stderr", "Environment", "Result message", "Configure
arguments", and "Command"). Here's another example with a
"Configure arguments" filter:
