Example 1 with Organizer

the class Controller method report.

/**
 * This method is called when the VM is exiting to provide a hook to allow
 * the adaptive optimization subsystem to generate a summary report.
 * It can also be called directly from driver programs to allow
 * reporting on a single run of a benchmark that the driver program
 * is executing in a loop (in which case the adaptive system isn't actually
 * exiting.....so some of the log messages may get a little weird).
