General:
- On Windows, you now need to install WSL2 as the native builds are now disabled.
It was not really working anyway.
+ - Remove the Java bindings: they were completely outdated, limited to the MSG interface.

you are studying or to create an atomic section that spans over
several simcalls), you obviously cannot use regular synchronization

+mechanisms (pthread_mutexes in C).
This is because the SimGrid kernel locks all processes and unlock them
one after the other when they are supposed to run, until they give the
control back in their simcall. If one of them gets locked by the OS
Instead, you should use the synchronization mechanism provided by the
simulation kernel. This could with a SimGrid mutex, a SimGrid
condition variables or a SimGrid semaphore, as described in @ref
-msg_synchro (in Java, only semaphores are available). But actually,
+msg_synchro. But actually,
many synchronization patterns can be encoded with communication on
mailboxes. Typically, if you need one process to notify another one,
you could use a condition variable or a semaphore, but sending a
install_cmake_outsrc) in addition to your main build tree.
To not mess with git, you want to put your build tree under the build/
directory, which is ignored by git. For example, I have the following
-directories: build/clang build/java build/full
+directories: build/clang build/full
(but YMMV).
Then, the problem is that when you traverse these directories, you
- examples/cpp/ for examples using the S4U API
- examples/smpi/ or examples using the SMPI API
- examples/platforms/ only contains platforms descriptions in the XML format (see @ref platform for details)
- - examples/deprecated/java/ for examples using the Java bindings to the MSG API. This directory contains packages (app, async,
- cloud, ...) which in turn contain individual examples. If your new example fits in an existing package, add it here,
- or create a new package otherwise.
-
+
In each of these directories, there is a CMakeLists.txt file that has
to be edited to include the new examples.

- **thread:** very slow factory using full featured, standard threads.
They are slow but very standard. Some debuggers or profilers only work with this factory.
- - **java:** Java applications are virtualized onto java threads (that
- are regular system threads registered to the JVM)
- **ucontext:** fast factory using System V contexts (Linux and FreeBSD only)
- **boost:** This uses the `context

:cpp:func:`MSG_process_create_with_arguments` or
:cpp:func:`MSG_process_create_with_environment`.
- There is nothing to do in Java, as SimGrid uses introspection abilities to

-
:``start_time``: Useful to delay the start of your actor.
-1 starts the actor immediately.
In practice, a SimGrid simulation is a suite of so-called **scheduling
rounds**, during which all actors that are not currently blocked on a
simcall get executed. For that, maestro passes the control flow to the
-code of each actor, that are written in either C++, C, Fortran, Python,
-or Java. The control flow then returns to the maestro when the actor

+The control flow then returns to the maestro when the actor
blocks on its next blocking simcall. Note that the time it takes to
execute the actor code has to be reported to the simulator using
execution activities. SMPI programs are automatically benchmarked
for the sake of simulation performance. SimGrid provides several
implementations of this mechanism, called **context factories**. These
implementations fall into two categories: Preemptive contexts are
-based on full-fledged system threads such as pthread on Linux or Java
-threads in the JVM. They are usually better supported by external

+They are usually better supported by external
debuggers and profiling tools, but less efficient. The most efficient
factories use non-preemptive mechanisms, such as SysV's ucontexts,
boost's context, or our own hand-tuned implementation, that is written

-^^^^^^^^^^^^^^^^^^^
-
-The jar file can be retrieved from the `Release page

-self-contained, including the native components for Linux, macOS and
-Windows. Copy it to your project's classpath and you're set.

-Nightly built Java Package
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Head to the corresponding `GitHub Action <https://github.com/simgrid/simgrid/actions/workflows/jarfile.yml>`_
-and pick the last green build. At the bottom of the build page, click on the ``jar-final`` artefact.
-Open this zip file to find the jar you need. This jar can be used under Linux, Mac OSX or Windows, as you wish.

-Binary Java Troubleshooting
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Here are some error messages that you may get when trying to use the
-binary Java package.
-
-Your architecture is not supported by this jarfile
- If your system is not supported, you should compile your
- own jarfile :ref:`by compiling SimGrid <install_src>` from the source.
-Library not found: boost-context
- You should obviously install the ``boost-context`` library on your
- machine, for example with ``apt``.

Version numbering and deprecation
- On CentOS / Fedora: ``dnf install eigen3-devel``
- On macOS with homebrew: ``brew install eigen``
- Use EIGEN3_HINT to specify where it's installed if cmake doesn't find it automatically.
-Java (optional):
- - Debian / Ubuntu: ``apt install default-jdk libgcj18-dev`` (or
- any version of libgcj)
- - macOS: Grab a `full JDK <http://www.oracle.com/technetwork/java/javase/downloads>`_

- **make simgrid**: Build only the SimGrid library. Not any example nor the helper tools.
- **make s4u-comm-pingpong**: Build only this example (works for any example)

-Java-specific instructions
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Once you have the `full JDK <http://www.oracle.com/technetwork/java/javase/downloads>`_ installed,
-things should be as simple as:
-
-.. code-block:: console
-
- $ cmake -Denable_java=ON -Dminimal-bindings=ON .
- $ make simgrid-java_jar # Only build the jarfile
-
-After the compilation, the file ```simgrid.jar``` is produced in the
-root directory.
-
-**Troubleshooting Java Builds**
-
-Sometimes, the build system fails to find the JNI headers. First locate them as follows:
-
-.. code-block:: console
-
- $ locate jni.h
- /usr/lib/jvm/java-8-openjdk-amd64/include/jni.h
- /usr/lib/jvm/java-9-openjdk-amd64/include/jni.h
- /usr/lib/jvm/java-10-openjdk-amd64/include/jni.h
-
-
-Then, set the JAVA_INCLUDE_PATH environment variable to the right
-path, and relaunch cmake. If you have several versions of JNI installed
-(as above), pick the one corresponding to the report of
-``javac -version``
-
-.. code-block:: console
-
- $ export JAVA_INCLUDE_PATH=/usr/lib/jvm/java-8-openjdk-amd64/include/
- $ cmake -Denable_java=ON .
- $ make
-
-Note that the filename ```jni.h``` was removed from the path.

-Building the Java examples in Eclipse
--------------------------------------
-
-If you want to build our Java examples in Eclipse, get the whole
-source code and open the archive on your disk. In Eclipse, select
-the menu "File / Import", and then in the wizard "General / Existing
-Project into Workspace". On the next page, select the directory
-"examples/deprecated/java" that you can find in the SimGrid source tree as a root
-directory and finish the creation.
-
-The file ``simgrid.jar`` must be in the root directory of the SimGrid
-tree. That's where it is built by default, but if you don't want to
-compile it yourself, just grab that file from the SimGrid website and
-copy it in here.
-
-Please note that once you better understand SimGrid, you should not
-modify the examples directly but instead create your own project in
-eclipse. This will make it easier to upgrade to another version of
-SimGrid.

-
-Welcome to the javasphinx user's guide.
-
-Introduction
-============
-
-javasphinx is a Sphinx_ extension that provides a Sphinx domain_ for documenting
-Java projects and a ``javasphinx-apidoc`` command line tool for automatically
-generating API documentation from existing Java source code and Javadoc
-documentation.
-
-.. _Sphinx: http://sphinx-doc.org
-.. _domain: http://sphinx-doc.org/domains.html
-
-Installing
-==========
-
-javasphinx is available in the Python Package Index (PyPi) and can be installed
-using tools such as ``pip`` or ``easy_install``,
-
-.. code-block:: sh
-
- $ pip install javasphinx
-
-or,
-
-.. code-block:: sh
-
- $ easy_install -U javasphinx
-
-Configuration
-=============
-
-To enable javasphinx for your existing Sphinx configuration add ``'javasphinx'``
-to the list of extensions in your conf.py file. javasphinx can be configured to
-cross link to external sources of documentation using the ``javadoc_url_map``
-option,
-
-.. code-block:: python
-
- javadoc_url_map = {
- 'com.netflix.curator' : ('http://netflix.github.com/curator/doc', 'javadoc'),
- 'org.springframework' : ('http://static.springsource.org/spring/docs/3.1.x/javadoc-api/', 'javadoc'),
- 'org.springframework.data.redis' : ('http://static.springsource.org/spring-data/data-redis/docs/current/api/', 'javadoc')
- }
-
-Each key in the map should be a Java package. Each value is a tuple of the form
-``(base_url, doc_type)`` where ``base_url`` is the base URL of the documentation
-source, and ``doc_type`` is one of,
-
-``javadoc``
- For documentation generated by the Javadoc tool *before* version 8.
-
-``javadoc8``
- For documentation generated by the Javadoc tool after version 8. This is
- required due to changes in how method anchors are generated (see JDK-8144118_).
-
-``sphinx``
- For external documentation generated by javasphinx.
-
-When comparing referenced types to the list of available packages the longest
-match will be used. Entries for ``java``, ``javax``, ``org.xml``, and
-``org.w3c`` packages pointing to http://docs.oracle.com/javase/8/docs/api are
-included automatically and do not need to be defined explicitly.
-
-.. _JDK-8144118: https://bugs.openjdk.java.net/browse/JDK-8144118
-
-Java domain
-===========
-
-Directives
-----------
-
-The Java domain uses the name **java** and provides the following directives,
-
-.. rst:directive:: .. java:type:: type-signature
-
- Describe a Java type. The signature can represent either a class, interface,
- enum or annotation declaration.
-
- Use the ``param`` field to document type parameters.
-
- Example,
-
- .. code-block:: rst
-
- .. java:type:: public interface List<E> extends Collection<E>, Iterable<E>
-
- An ordered collection (also known as a *sequence*)
-
- :param E: type of item stored by the list
-
- produces,
-
- .. java:type:: public interface List<E> extends Collection<E>, Iterable<E>
-
- An ordered collection (also known as a *sequence*)
-
- :param E: type of item stored by the list
-
-.. rst:directive:: .. java:field:: field-signature
-
- Describe a Java field.
-
-.. rst:directive:: .. java:method:: method-signature
-
- Describe a Java method.
-
- Use the ``param`` field to document parameters.
-
- Use the ``throws`` field to document exceptions thrown by the method.
-
- Use the ``return`` field to document the return type
-
-.. rst:directive:: .. java:constructor:: constructor-signature
-
- Describe a Java constructor.
-
- Use the ``param`` field to document parameters.
-
- Use the ``throws`` field to document exceptions thrown by the constructor.
-
-.. rst:directive:: .. java:package:: package
-
- Provide package-level documentation and also sets the active package for the
- type, method, field, constructors, and references that follow.
-
- Use the ``:noindex:`` option if the directive is only being used to specify
- the active package. Only one directive for a given package should exclude
- ``:noindex:``.
-
-.. rst:directive:: .. java:import:: package type
-
- Declare the given type as being provided by the given package. This
- information helps javasphinx create cross references for types in type,
- method, and field declarations. It also allows explicit cross references
- (using the ``java:ref`` role) to exclude the package qualification.
-
-The method, construct, field, and type directives all accept the following
-standard options,
-
-.. describe:: package
-
- Specify the package the declaration is within. Can be used instead of, or to
- override, a ``java:package`` directive.
-
-.. describe:: outertype
-
- Specify the class/interface the documented object is contained within. This
- option should be provided for any constructor, method, or field directive
- that isn't nested within a corresponding type directive.
-
-Roles
------
-
-The following roles are provided,
-
-.. rst:role:: java:ref
-
- This role can be used to create a cross reference to any object type within
- the Java domain. Aliases for this role include ``java:meth``, ``java:type``,
- ``java:field``, ``java:package``, and ``java:construct``.
-
- An explicit title can be provided by using the standard ``title <reference>``
- syntax.
-
-.. rst:role:: java:extdoc
-
- This role can be used to explicitly link to an externally documented
- type. The reference must be fully qualified and supports an explicit title
- using the ``title <reference>`` syntax.
-
- The ``java:ref`` role will also create external references as a fall-back if
- it can't find a matching local declaration so using this role is not strictly
- necessary.
-
-javasphinx-apidoc
-=================
-
-The ``javasphinx-apidoc`` tool is the counterpoint to the ``sphinx-apidoc`` tool
-within the Java domain. It can be used to generate reST source from existing
-Java source code which has been marked up with Javadoc-style comments. The
-generated reST is then processed alongside hand-written documentation by Sphinx.
-
-At minimum a source and destination directory must be provided. The input
-directory will be scanned for .java files and documentation will be generated
-for all non-private types and members. A separate output file will be generated
-for each type (including inner classes). Each file is put within a directory
-corresponding to its package (with periods replaced by directory separators) and
-with the basename of the file deriving from the type name. Inner types are
-placed in files with a basename using a hyphen to separate inner and outer
-types, e.g. ``OuterType-InnerType.rst``.
-
-By default ``javasphinx-apidoc`` will not override existing files. Two options
-can change this behavior,
-
-.. option:: -f, --force
-
- All existing output files will be rewritten. If a cache directory is
- specified it will be rebuilt.
-
-.. option:: -u, --update
-
- Updated source files will have their corresponding output files
- updated. Unchanged files will be left alone. Most projects will want to use
- this option.
-
-For larger projects it is recommended to use a cache directory. This can speed
-up subsequent runs by an order of magnitude or more. Specify a directory to
-store cached output using the :option:`-c` option,
-
-.. option:: -c, --cache-dir
-
- Specify a directory to cache intermediate documentation representations. This
- directory will be created if it does not already exist.

-Java bindings
-*************
-
-This section describes jMSG, the Java API to Simgrid. This API mimics
-:ref:`MSG <MSG_doc>`, which is a simple yet somehow realistic interface.
-The full reference documentation is provided at the end of this page.
-
-Most of the documentation of the :ref:`MSG API <MSG_doc>` in C applies
-directly to the Java bindings (any divergence is seen as a bug that we
-should fix). MSG structures are mapped to Java objects as expected,
-and the MSG functions are methods in these objects.
-
-Installing the Java bindings
-============================
-
-The easiest is to use a :ref:`precompiled jarfile <install_java_precompiled>`,
-but some people may prefer to :ref:`compile it from the sources <install_src>`.
-
-
-Using the Java bindings
-=======================
-
-In most cases, you can use the SimGrid bindings as if it was a Java
-library:
-
-.. code-block:: console
-
- $ javac -classpath .:path/to/simgrid.jar your/java/Code.java
- $ java -classpath .:path/to/simgrid.jar your.java.Code the/parameter/to/your/code
-
-For example:
-
-.. code-block:: console
-
- $ cd examples/deprecated/java
- $ java -classpath ../../simgrid.jar:. .:../../simgrid.jar app.pingpong.Main ../platforms/platform.xml
-
-Any SimGrid simulation (java or not) is usually constituted of several
-kind of actors or processes (classes extending @c Msg.Process) that
-are deployed over the hosts of the virtual platform. So, your code
-should declare these actors, plus a Main class in charge of deploying
-your actors on the platform. Please refer to the examples for details.
-
-Troubleshooting
-===============
-
-Actually, these bindings are not only implemented in Java. They do use
-the C implementation of SimGrid. This should be transparent as this
-library is directly included in the ``simgrid.jar`` file but things can
-still go wrong is several ways.
-
-Error: library simgrid not found
---------------------------------
-
-This means that the JVM fails to load the native library. If you use a
-precompiled jarfile, please report this bug.
-
-If you built it yourself, you can try to use an installed version of
-the library instead of the one included in the jar. For that, add the
-path to the native library into the ``LD_LIBRARY_PATH`` variable (or in
-the ``DYLD_LIBRARY_PATH`` on macOS).
-
-pthread_create failed
----------------------
-
-You reached the amount of threads that can be run on your system. Try
-increasing the thread limits of your operating system.
-
-Other errors
-------------
-
-When using jMSG, your program can crash for 3 main reasons:
-
-- Your Java part is not good: you'll have a good old java exception thrown,
- and hence you should be able to correct it by yourself.
-- Our java part is not good: you'll also have a java exception thrown, but
- we have real doubts this can happen, since the java part is only a JNI
- binding. The other option is that it crashed because you used incorrectly
- the MSG API, so this means also you should have an MSGException. It means
- you should read carefully MSG samples and/or documentation.
-- Something has crashed in the C part. Okay, here comes the tricky
- thing. It happens mainly for 2 reasons:
-
- - When something goes wrong in your simulation, sometimes the C part stops
- because you used SimGrid incorrectly, and JNI bindings are not fond of that.
- It means that you'll have something that looks ugly, but you should be able
- to identify what's going wrong in your code by carefully reading the whole
- error message
- - It may happen that the problem comes directly from SimGrid: in this case,
- the error should be uglier. In that case, you may submit a bug directly to
- SimGrid.

Technically speaking, SimGrid is a library. It is neither a graphical
interface nor a command-line simulator running user scripts. The
interaction with SimGrid is done by writing programs with the exposed
-functions to build your own simulator. This can be done in C/C++, Python or Java,

on Linux, Mac OSX or Windows (using the WSL).

-This is a somehow basic master/workers example.
-
-There is 2 kind of processes:
- * Master: creates some tasks, and dispatches them to its workers
- * Worker: get tasks from the master and run them
-
-At the end of the execution:
- - the master sends a Task whose name is "finalize" to every known worker to stop them
- - On reception of such tasks workers stop.

-There are two tests:
-- The first one aims at validating the migration in presence of consolidated VMs
-- The second one aims at validating the robustness of the migration process (the SRC node or the DST node are turned off during the migration process)
-
-To switch between the first and the second tests, you should instrument Main.java (sorry for that :( )
-Adsein - Thu Oct 9 18:25:39 CEST 2014

-UPDATE: the second test was never used (dit it ever work?), and was removed 4 years later
