+@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
+ simulator binary, highlighting how to pass options to the simulators
(as detailed in Section \ref options).
- <b>Token Ring</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
until all activities in a given set have completed.
- <b>Waiting for the first completed communication in a set</b>.
- @ref examples/msg/async-waitall/async-waitany.c\n
+ @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
You can specify a start time and a kill time in the deployment
file. See all *_d.xml files in this directory.
-TODO: add an example using @ref MSG_process_create()
-
@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".
- - <b>Basic example</b>. @ref examples/msg/trace-simple/trace-simple.c \n
- In this very simple program, each process creates, executes,
- and destroy a task. Recommanded options:
- @verbatim --cfg=tracing:yes --cfg=tracing/uncategorized:yes @endverbatim
+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
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
+ @verbatim --cfg=tracing:yes --cfg=tracing/categorized:yes --cfg=tracing/uncategorized:yes
@endverbatim
- <b>Master Workers tracing</b>.
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
+ @verbatim --cfg=tracing/categorized:yes --cfg=tracing/uncategorized:yes
@endverbatim
- <b>Process migration tracing</b>.
@endverbatim
TODO: These tracing examples should be integrated in the examples to
-not dupplicate the C files. A full command line to see the result in
-the right tool (viva/vite/FrameSoc) should be given along with some
+not duplicate the C files. A full command line to see the result in
+the right tool (vite/FrameSoc) should be given along with some
screenshots.
@subsection msg_ex_tracing_user_variables Tracing user variables
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-user-variables/trace-user-variables.c
-
+ @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-link-srcdst-user-variables/trace-link-srcdst-user-variables.c \n
+ @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. The most
+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 PLS bindings
+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.
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/
