In addition, this constitutes a good introductory example on how to write a plugin.
It attaches an extension to each host to store some data, and places callbacks in the following signals:
- - :cpp:member:`simgrid::s4u::Host::on_creation`: Attach a new extension to the newly created host.
- - :cpp:member:`simgrid::s4u::Exec::on_start`: Make note that a new execution started, increasing the load.
- - :cpp:member:`simgrid::s4u::Exec::on_completion`: Make note that an execution completed, decreasing the load.
- - :cpp:member:`simgrid::s4u::Host::on_state_change`: Do what is appropriate when the host gets suspended, turned off
+ - :cpp:func:`simgrid::s4u::Host::on_creation_cb`: Attach a new extension to the newly created host.
+ - :cpp:func:`simgrid::s4u::Exec::on_start_cb`: Make note that a new execution started, increasing the load.
+ - :cpp:func:`simgrid::s4u::Exec::on_completion_cb`: Make note that an execution completed, decreasing the load.
+ - :cpp:func:`simgrid::s4u::Host::on_state_change_cb`: Do what is appropriate when the host gets suspended, turned off
or similar.
- - :cpp:member:`simgrid::s4u::Host::on_speed_change`: Do what is appropriate when the DVFS is modified.
+ - :cpp:func:`simgrid::s4u::Host::on_speed_change_cb`: Do what is appropriate when the DVFS is modified.
Note that extensions are automatically destroyed when the host gets destroyed.
