+SimGrid (3.7) NOT RELEASED; urgency=low
+
+ The "sprint cleanups (before spring)" release.
+
+ Models:
+ * We can specify the smpi latency/bandwidth factor with command line
+ add --cfg=smpi/bw_factor:"threshold0:value0;...;thresholdN:valueN"
+ or add --cfg=smpi/lat_factor:"threshold0:value0;...;thresholdN:valueN"
+ You can also use the "config tag" from platform file by adding this line
+ <prop id="smpi/bw_factor" value="threshold0:value0;...;thresholdN:valueN"></prop>
+ (see "example/platforms/tag_config.xml" to use "config tag").
+ Note that the command line supersedes the platform file configuration.
+ * Change the correction factors used in LMM model, according to
+ the latest experiments described in INRIA RR-7821.
+ Accuracy should be improved this way.
+ (TODO: this is not true in the code, yet)
+ * Use the partial invalidation optimization by default for the
+ network too. Should produce the exact same results, only faster.
+ * Major cleanup in surf to merge models and split some optimization
+ mechanisms from the core of the models. As a result you can now
+ specify which model to use (e.g., --cfg=network/model:LV08
+ --cfg=cpu/model:Cas01) and which optimization mode to use
+ (e.g., --cfg=network/optim:lazy --cfg=cpu/optim:TI).
+ Incompatible combinations should err at initialization. See
+ --help-models for the list of all models and optimization modes.
+ * The CLM03 workstation model was dropped for simplicity because it
+ used the deprecated CM02 network model. Use default instead.
+ * Rename the TCP_gamma configuration option to network/TCP_gamma
+ * Rename the coordinates configuration option to
+ network/coordinates, and document it
+ * Use now crosstraffic keyword instead of the terribly misleading
+ fullduplex keyword. It is activated by default now in the current
+ default model, use --cfg=network/crosstraffic:0 to turn it off.
+ * Experimental: new configuration option --cfg=surf/nthreads:N to run
+ analytical models in parallel with N threads (default is 1).
+ * Ongoing refactoring the model parsing to make XML files optional
+ (more work is needed here to fully achieve this goal)
+
+ MSG:
+ * Deprecate the use of m_channel_t mecanism like MSG_task_{get,put}
+ functions and friends. This interface was considered as
+ deprecated since over 2 years, it's time to inform our users that it is.
+ Switch to MSG_task_{send,recv} instead, or compile Simgrid command line
+ 'cmake -Dcustom_flags="-DMSG_USE_DEPRECATED" .' if you really need to
+ use these (crappy) functions in your code.
+ These functions will be removed at some point. Stop using them now.
+ * Deprecate MSG_get_host_{table,number}
+ Implement MSG_hosts_as_dynar() instead.
+ * Implement MSG_processes_as_dynar() (Closes gforge #13642)
+
+ Simix:
+ * Stabilize the parallel execution mode of user contexts
+ * Introduce configuration variables to control parallel execution:
+ - contexts/synchro: Synchronization mode to use when running
+ contexts in parallel (either futex, posix or busy_wait)
+ - contexts/parallel_threshold: Minimal number of user contexts
+ to be run in parallel (raw contexts only)
+
+ SURF:
+ * Introduce a parallel mode for the models (see surf/nthreads
+ configuration item). In our tests, running the models in parallel
+ never lead to any speedups because they are so fast that the gain
+ of computing each model in parallel does not amortizes the
+ synchronization costs, even when ultra fast futexes are used.
+ This is released anyway because YMMV.
+
+ SimDag:
+ * Performance boost by using a swag internally to compute the set of
+ tasks that are finished and should constitute the return value of
+ SD_simulate.
+
+ SMPI:
+ * Enable it by default now that it is considered rather stable.
+
+ TRACE:
+ * Documentation of the tracing functions.
+ * Performance gains when tracing categorized/uncategorized resource
+ utilization by avoiding calls to get route when updating resource
+ variables. LMM constraints are being used instead.
+ * API changed to set task categories. Use MSG_task_set_category instead
+ of TRACE_msg_set_task_category, and SD_task_set_category instead
+ of TRACE_sd_set_task_category. They only work if ENABLE_TRACING is ON.
+ * Bugfix for graphicator, routes not correctly obtained, memory leaks
+ * Examples for link user variables added (see at examples/msg/tracing/)
+ * Deprecated function TRACE_msg_set_process_category completely removed
+ * Trace header updated according to the latest Paje file format
+ * Tracing network lazy updates, no longer obligate users to use full updates
+ * --cfg=tracing/platform:1 also registers power/bandwidth variables
+
+ Lua:
+ * Improve the API of Lua MSG bindings, using the Lua spirit.
+ * Each simulated process now lives in its own Lua world (globals are
+ automatically duplicated). It helps writing simulators. This is also the
+ first step towards running real distributed Lua programs with SimGrid.
+ * Add a Chord example in Lua, equivalent to the MSG one.
+
+ XBT:
+ * Logs:
+ - Add new runtime parameters --help-logs and --help-log-categories
+ to display informations about supported logging parameters and
+ categories.
+ - Old deprecated parameters --{gras,surf,msg.simix,xbt}-log=...
+ don't exists anymore.
+ * Mallocators: allow value NULL for the reset function.
+ * Dicts:
+ - New function xbt_dict_new_homogeneous(void(*)(void*)) to
+ create homogeneous dictionaries, where all the elements share the
+ same free function. Non homogeneous dictionaries will be
+ deprecated in the next release.
+ - Dicts of scalar elements (xbt_dicti_*) are deprecated.
+ - Multi-level dictionaries are deprecated.
+ * mmalloc module:
+ - Cleanups and simplifications to make it maintainable again.
+ - Exotic features (such as memalign and valloc) were removed.
+ - The metadata were extended and improved so that the
+ model-checker becomes able to explore and inspect the heaps.
+ - This may induce a performance drop when enable_model-checking is
+ ON in cmake (even if it's not used in the simulation), but it is
+ necessary at this point to get MC working.
+
+ Turn model-checking OFF if simulation performance matters to you.

+SimGrid (3.6.2) stable; urgency=low
+
+ The "Not coding new stuff allows to polish old things" release.
+
+ General
+ * New bindings to the NS3 packet level simulator (experimental)
+ * Use the raw (efficient) execution contexts instead of the sysv
+ (portable) ones when possible.
+ * libpcre is now mandatory in any cases since not using it led to
+ severe performance loss and possibly other issues
+ * Update the XML platforms:
+ - G5K: include the latest machine in Nancy
+ - GridPP and LCG: new platforms
+ * Documentation was partially updated, at least (more to come)
+
+ Bug fixes, cosmetics and small improvements
+ * Free terminated processes before the end of the simulation to avoid
+ exhausting the memory of users having very dynamic amount of
+ processes.
+ * Bug fix and cosmetics about canceling non-running tasks
+ * Bug fix about the dot loader's issues when using libcgraph
+
+ Portability
+ * Create an installer for windows with nsis (amd64 and win32)
+ - Add an hello world project to illustrate simgrid project creation.
+ - Embed libpcre into the Simgrid installer to avoid
+ its compilation burden
+ * The raw execution contexts should work on Apple now
+ * Port to Windows 64 bits
+ - Sysv contexts now have an implementation for this arch
+ - GRAS communication features now support this arch
+ * Drop support for borland compiler on windows
+ - this code was not maintained, and we kinda depend on gcc nowadays
+ * Fix portability issues on kfreebsd/gnu: build error about semaphores
+ * Fix portability issue on unstable ubuntu: linker became picky on
+ argument order

+
+SimGrid (3.6.1) stable; urgency=low
+
+ The "Oops, we broke Macs too" release
+
+ Portability
+ * Fixed contexts detection so that raw ones are used when possible
+ * On Mac, do not use Posix Ucontexts with gcc v4.[1-5] since this
+ leads to a strange error, with user code segfaulting sometimes when
+ the generated code is not perfectly aligned (which is not
+ controllable from the user side, depends on the amount of code)
+
+ XBT
+ * New macro: CATCH_ANONYMOUS, which is like CATCH(e) but without argument.

+
+SimGrid (3.6) stable; urgency=medium
+
+ The Summer Release, also known as the "OMG! They Killed Kenny!" version
+
+ Java and Ruby:
+ * Bindings now constitute their own package, separated from the main one.
+ Rationale: reduce our maintenance nightmare by reducing the module coupling
+ They will soon be released on their own on gforge.
+ * In the meanwhile:
+ svn co svn://scm.gforge.inria.fr/svn/simgrid/contrib/trunk/simgrid-java
+ svn co svn://scm.gforge.inria.fr/svn/simgrid/contrib/trunk/simgrid-ruby
+
+ GRAS: It is not considered as stable anymore, but experimental. Sorry.
+ * It's not quite deprecated for now because we have no replacement,
+ but it may soon become the case.
+
+ SMPI
+ * New MPI functions supported: MPI_Comm_disconnect, MPI_Comm_get_name
+ * Fortran: New user-level cache variable to store the rank of the running
+ process. This improves performance by an order of magnitude.
+ * C: New coccinelle script to automatically locate and modify global and
+ local static variables.
+ * Improved SMPI network model with a sender-side gap to account for multiple
+ parallel sends.
