run_valgrind_interactive()

def carputils.debug.run_valgrind_interactive	(		command,
			executable,
			args,
			kwargs
	)

Run an MPI command and attach GDB instances with valgrind.

Diverts the output of the MPI job to a stream which filters for valgrind's prompt to attach GDB instances to specific process indicies. When the regular expression searching for this is matched, a callback is run which automatically attaches the GDB instances.

Parameters

command str The MPI command to execute
