-@section msg_ex_basics Basic examples and features
-
- - <b>Ping Pong</b>: @ref examples/msg/app-pingpong/app-pingpong.c\n
- It's hard to think of a simpler example: it is just sending one
- message back and forth.
- The tesh file laying in the directory show how to start the
- simulator binary, enlighting how to pass options to the simulators
- (as detailed in Section \ref options).
-
- - <b>Token Ring</b>.
- @ref examples/msg/app-token-ring/app-token-ring.c\n
- Classical communication pattern, where a token is exchanged
- along a ring to reach every participant.
- The tesh file laying in the directory shows how to run the same
- example on different virtual platforms.
-
- - <b>Master Workers</b>.
- @ref examples/msg/app-masterworker/app-masterworker.c\n
- Another good old example, where one Master process has a bunch of
- task to dispatch to a set of several Worker processes. It is fully
- commented in @ref msg_ex_master_worker.
-
-@section msg_ex_async Asynchronous communications
-
-In addition to the fully documented example of @ref
-msg_ex_asynchronous_communications, there are several other examples
-shipped in the archive:
-
- - <b>Basic asynchronous communications</b>.
- @ref examples/msg/async-wait/async-wait.c \n
- Illustrates how to have non-blocking communications, that are
- communications running in the background leaving the process free
- to do something else during their completion. The main functions
- involved are @ref MSG_task_isend, @ref MSG_task_irecv, and @ref
- MSG_comm_wait.
-
- - <b>Waiting for all communications in a set</b>.
- @ref examples/msg/async-waitall/async-waitall.c\n
- The @ref MSG_comm_waitall function is useful when you want to block
- until all activities in a given set have completed.
-
- - <b>Waiting for the first completed communication in a set</b>.
- @ref examples/msg/async-waitany/async-waitany.c\n
- The @ref MSG_comm_waitany function is useful when you want to block
- until one activity of the set completes, no matter which terminates
- first.
-
-@section msg_ex_process Acting on Processes
-
- - <b>Creating processes</b>.
- @ref examples/msg/process-create/process-create.c \n
- Most processes are started from the deployment XML file, but they
- can also be used with the @ref MSG_process_create() function.
-
- - <b>Suspend and Resume processes</b>.
- @ref examples/msg/process-suspend/process-suspend.c \n
- Processes can be suspended and resumed during their executions
- thanks to the @ref MSG_process_suspend and @ref MSG_process_resume functions.
-
- - <b>Kill processes</b>.
- @ref examples/msg/process-kill/process-kill.c \n
- Processes can forcefully stop other processes with the @ref MSG_process_kill function.
-
- - <b>Migrating processes</b>.
- @ref examples/msg/process-migration/process-migration.c \n
- Processes can move or be moved from a host to another with the @ref MSG_process_migrate function.
-
- - <b>Controling the process life cycle from the XML</b>.
- @ref examples/msg/process-startkilltime/process-startkilltime.c \n
- You can specify a start time and a kill time in the deployment
- file. See all *_d.xml files in this directory.
-
-@section msg_ex_tracing Tracing and visualization features
-
-Tracing can be activated by various configuration options which
-are illustrated in these example. See also the
-@ref tracing_tracing_options "full list of options related to tracing".
-
-It is interesting to run the process-create example with the following
-options to see the task executions:
-
- - <b>Platform tracing</b>.
- @ref examples/msg/trace-platform/trace-platform.c \n
- This program is a toy example just loading the platform, so that
- you can play with the platform visualization. Recommanded options:
- @verbatim --cfg=tracing:yes --cfg=tracing/categorized:yes
- @endverbatim
-
- - <b>Setting Categories</b>.
- @ref examples/msg/trace-categories/trace-categories.c \n
- This example declares several tracing categories
- to that are used to classify its tasks. When the program is executed,
- the tracing mechanism registers the resource utilization of hosts
- and links according to these categories. Recommanded options:
- @verbatim --cfg=tracing:yes --cfg=tracing/categorized:yes --cfg=tracing/uncategorized:yes --cfg=viva/categorized:viva_cat.plist --cfg=viva/uncategorized:viva_uncat.plist
- @endverbatim
-
- - <b>Master Workers tracing</b>.
- @ref examples/msg/trace-masterworker/trace-masterworker.c \n
- This is an augmented version of our basic master/worker example
- using several tracing features. It traces resource usage, sorted
- out in several categories; Trace marks and user variables are also
- used. Recommanded options:
- @verbatim --cfg=tracing/categorized:yes --cfg=tracing/uncategorized:yes --cfg=viva/categorized:viva_cat.plist --cfg=viva/uncategorized:viva_uncat.plist
- @endverbatim
-
- - <b>Process migration tracing</b>.
- @ref examples/msg/trace-process-migration/trace-process-migration.c \n
- This version is enhanced so that the process migrations can be
- displayed as arrows in a Gantt-chart visualization. Recommanded
- options to that extend:
- @verbatim -cfg=tracing:yes --cfg=tracing/msg/process:yes
- @endverbatim
-
-TODO: These tracing examples should be integrated in the examples to
-not duplicate the C files. A full command line to see the result in
-the right tool (viva/vite/FrameSoc) should be given along with some
-screenshots.
-
-@subsection msg_ex_tracing_user_variables Tracing user variables
-
-You can also attach your own variables to a any resource described in
-the platform file. The following examples illustrate this feature.
-They have to be run with the following options:
-@verbatim --cfg=tracing:yes --cfg=tracing/platform:yes
-@endverbatim
-
- - <b>Attaching variables to Hosts</b>.
- @ref examples/msg/trace-host-user-variables/trace-host-user-variables.c
-
- - <b>Attaching variables to Links</b>.
- @ref examples/msg/trace-link-user-variables/trace-link-user-variables.c \n
- The tricky part is that you have to know the name of the link you
- want to enhance with a variable.
-
- - <b>Attaching variables to network Routes</b>
- @ref examples/msg/trace-route-user-variables/trace-route-user-variables.c \n
- It is often easier to update a given variable for all links of a
- given network path (identified by its source and destination
- hosts) instead of knowing the name of each specific link.
-
-@section msg_ex_models Models-related examples
-
-@subsection msg_ex_ns3 NS3 as a SimGrid Network Model
-
-This example demonstrates how to use the bindings to the Network
-Simulator, as explained in @ref pls_ns3. The most
-interesting is probably not the C files since they are unchanged from
-the other simulations, but the associated files, such as the platform
-file to see how to declare a platform to be used with the ns-3 bindings
-of SimGrid and the tesh file to see how to actually start a simulation
-in these settings.
-
- - @ref examples/msg/network-ns3/network-ns3.c. Simple ping-pong using
- ns-3 instead of the SimGrid network models.
-
-TODO: merge the C files
-
-TODO: show the XML files instead if it's what is interesting. On a "XML example files" page that does not exist yet.
-
-@subsection msg_ex_io Simulating disks and files
-
-The examples of this section demonstrate how to interact with the
-simulated storages.
-
- - <b>Basic example</b>.
- @ref examples/msg/io-storage/io-storage.c \n
- All main storage and file functions are demoed.
-
- - <b>File Management</b>. @ref examples/msg/io-file/io-file.c \n
- This example illustrates the use of operations on file
- (@ref MSG_file_open, @ref MSG_file_read, @ref MSG_file_write,
- or @ref MSG_file_close).
-
- - <b>Remote I/O</b>. @ref examples/msg/io-remote/io-remote.c \n
- I/O operations can also be done in a remote, i.e. when the
- accessed disk is not mounted on the caller's host.
-
-@section msg_ex_actions Following Workload Traces
-
-This section details how to run trace-driven simulations. It is very
-handy when you want to test an algorithm or protocol that only react
-to external events. For example, many P2P protocols react to user
-requests, but do nothing if there is no such event.
-
-In such situations, you should write your protocol in C, and separate
-the workload that you want to play onto your protocol in a separate
-text file. Declare a function handling each type of the events in your
-trace, register them using @ref xbt_replay_action_register in your
-main, and then use @ref MSG_action_trace_run to launch the simulation.
-
-Then, you can either have one trace file containing all your events,
-or a file per simulated process: the former may be easier to work
-with, but the second is more efficient on very large traces. Check
-also the tesh files in the example directories for details.
-
- - <b>Communication replay</b>.
- @ref examples/msg/actions-comm/actions-comm.c \n
- Presents a set of event handlers reproducing classical communication
- primitives (synchronous and asynchronous send/receive, broadcast,
- barrier, etc).
-
- - <b>I/O replay</b>.
- @ref examples/msg/actions-storage/actions-storage.c \n
- Presents a set of event handlers reproducing classical I/O
- primitives (open, read, write, close, etc).
-
-@section msg_ex_apps Examples of Full Applications
-
- - <b>Parallel Matrix Multiplication</b>.
- @ref examples/msg/app-pmm/app-pmm.c \n
- This little application multiplies two matrices in parallel. Each
- of the 9 processes computes a sub-block of the result, with the
- sub-blocks of the input matrices exchanged between the processes. \n
- This is a classical assignment in MPI lectures, here implemented
- in MSG.
-
- - <b>Chord P2P protocol</b>.
- @ref examples/msg/dht-chord/dht-chord.c \n
- This example implements the well known Chord protocol,
- constituting a fully working non-trivial example. This
- implementation is also very efficient, as demonstrated in
- http://hal.inria.fr/inria-00602216/
-
-@section msg_ex_misc Miscellaneous
-
- - <b>Task priorities</b>.
- @ref examples/msg/task-priority/task-priority.c \n
- Demonstrates the use of @ref MSG_task_set_priority to change the
- computation priority of a given task.
-
- - <b>User-defined properties</b>.
- @ref examples/msg/platform-properties/platform-properties.c \n
- Attaching arbitrary information to host, processes and
- such, and retrieving them with @ref MSG_host_get_properties,
- @ref MSG_host_get_property_value, @ref MSG_process_get_properties, and
- @ref MSG_process_get_property_value. Also make sure to read the
- platform and deployment XML files to see how to declare these data.
-
-TODO: Document the many other examples that we have
-*/
-
-As a human, you can stop reading at this point. The rest is garbage:
-
-Every example must be listed in the following, but it's not possible
-to move this content upper as each @example directive seems to eat
-everything until the next */ marker (and the content is placed at the
-top of the example file).
