       export an implementation of a Broker::TaskFactory.

SYNOPSIS

       exact_task_factory [-o ior-file] [-n name]

       glacial_task_factory [-o ior-file] [-n name]

       max_decay_task_factory [-o ior-file] [-n name]

       max_task_factory [-o ior-file] [-n name]

DESCRIPTION

       Each  of  these  utilities  create  and export a different
       implementation of the Broker::TaskFactory CORBA interface.
       This  interface  is  used  to produce objects that provide
       per-task resource usage sensing  and  reservation  adapta-
       tion.

       Available options:

       -o ior-file
              The  output file for the object's IOR. (Default for
              each        factory:        exact_task_factory.ior,
              glacial_task_factory.ior,       max_decay_task_fac-
              tory.ior, max_task_factory.ior)

       -n name
              The name  for  the  object  in  the  NamingService.
              (Default   for   each   factory:  ExactTaskFactory,
              GlacialTaskFactory,  MaxDecayTaskFactory,  MaxTask-
              Factory)

       Available factories:

       exact_task_factory
              This  factory  produces  ExactTaskAdvocate objects.
              An ExactTaskAdvocate adapts the reservation to  the
              exact  amount of resources consumed by the previous
              period.

       glacial_task_factory
              This factory produces GlacialTaskAdvocate  objects.
              A  GlacialTaskAdvocate  adapts  the  reservation by
              slowly changing the current values to the amount of
              resources consumed by the previous period.

       max_decay_task_factory
              This factory produces MaxDecayTaskAdvocate objects.
              A MaxDecayTaskAdvocate adapts  the  reservation  by
              changing it to the maximum observed usage over some
              number of periods.  Thus, the advocate can adapt to
              somewhat unpredicatable usage patterns without get-
              ting stuck in a local maxima.

       max_task_factory
              This factory produces MaxTaskAdvocate  objects.   A
              MaxTaskAdvocate  adapts the reservation by changing
              it to the maximum observed usage.
