37 @brief How to build a new API on top of SURF
39 SURF provides the functionalities to simulate the platform. There are two main data types in SURF:
40 the actions and the resources. Several types of resources exist:
42 - the network resource,
46 FIXME[donassolo]: fix doc
47 The implementation of these resources depends on the platform
48 models you choose. You can select your model by calling
49 #surf_host_model_init_current_default() (which will give you a
50 CLM03 model), or similar (see @ref SURF_models).
52 To initialize SURF, call #surf_init(). Then
53 #surf_host_model_init_current_default() or #surf_host_model_init_ptask_L07()
54 to create the platform.
56 Then you can access the hosts with the @ref simgrid::s4u::Engine::get_all_hosts.
57 Some functions of the @ref SURF_host_interface and similar can give
58 you some information about:
59 - a host: get_speed(), get_available_speed();
60 - a network link: get_link_name(), get_link_latency(), get_link_bandwidth();
61 - a route: get_route(), get_route_size().
63 During the simulation, call @a surf_host_model->execute() to schedule a
64 computation task on a host, or @a surf_host_model->communicate()
65 to schedule a communication task between two hosts. You can also create parallel task
66 with @a surf_host_model->extension_public->execute_parallel_task(). These functions return
67 a new action that represents the task you have just created.
69 To execute the actions created with @a execute(), @a communicate() or @a execute_parallel_task(), call
70 surf_solve(). The function surf_solve() is where the simulation takes place. It returns the
71 time elapsed to execute the actions. You can know what actions have changed their state thanks
72 to the states sets. For example, if your want to know what actions are finished,
73 extract them from @a surf_host_model->common_public->states.done_action_set.
74 Depending on these results, you can schedule other tasks and call surf_solve() again.
76 When the simulation is over, just call surf_exit() to clean the memory.
78 Have a look at the implementation of @ref MSG_API "MSG" and @ref SD_API "Simdag" to see how these module
79 interact with SURF. But if you want to create a new API on top of SURF,
80 we strongly recommend you to contact us before anyway.
