+SimGrid (3.6.1) unstable; urgency=low
+
+ The "Oops, we broke Macs too" release
+
+ Portability
+ * Fixed contextes detection so that raw ones are used when possible
+ * On Mac, do not use Posix Ucontextes 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
+ controlable from the user side, depends on the amount of code)
+
+ XBT
+ * New macro: CATCH_ANONYMOUS, which is like CATCH(e) but without argument.

+
+ 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 maintainance 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 modifiy global and
+ local static variables.
+ * Improved SMPI network model with a sender-side gap to account for multiple
+ parallel sends.
MSG
- * Change the prototypes of action replay. Sorry for inconvenience,
- but this is really more efficient this way (and to adapt your code,
- you just have to fix the initialization, that shouldn't be too long)
- * Kill the braindead MSG_task_refcount_dec() function. I guess nobody
- ever managed to do anything useful with it.
- * New function MSG_comm_testany(). Similarly to MSG_comm_waitany(), it
- takes a dynar of communications. It returns immediately and gives the
- index of a finished communication (if any).
* New function MSG_comm_get_status(). MSG_comm_test() and MSG_comm_testany()
only say if a communication is finished, no matter whether it succeeded or
failed. You can call MSG_comm_get_status() to know the status of a finished
communication is detached, you are never notified of its success or failure
and the memory is released automatically once it is finished. This function
is useful when you don't care about the end nor the success of a
- communication you send.

+ * New example: a basic implementation of the Chord P2P algorithm.
SURF
* New model for multi-core CPUs. You can now use the core attribute to
precise the number of cores of a host. This is a basic model. Every
- process running on the host receive at most the power provided in
+ process running on the host receives at most the power provided in
the DTD (throughput<=power). Total throughput of process cannot exceed

* New peer tag. This peer tag creates a tiny AS comprising a host and a
into a Vivaldi routing model (based on the rule-based model). This allows to
combine Vivaldi based latencies with last-mile platforms.
- Simix
- * Added a check for NaN of IEEE754 infinite in the double entries of
- the smx_user.c file
+ SIMIX
* Introduce a new context factory "raw", highly inspirated from the
ucontext factory, but using manually crafted functions in assembly to
do the work in an efficient manner.
with N parallel threads (the default is 1, meaning no parallelism).
* Allow to decide dynamically between sequential and parallel modes.
When nthreads > 1, you can use --cfg=contexts/threshold:P to run the user
- processes in parallel only when their number is greater than or equal to P.

+ (the default is 2).
+ * Added a check for NaN of IEEE754 infinite in the double entries of
+ the smx_user.c file
XBT
* New command line option: if you pass --cfg=verbose-exit:0, SimGrid
won't output the state of processes when interrupted with Ctrl-C
* Add a new function xbt_dynar_to_array that transforms a dynar into a
NULL-terminated array. This may solve backward compatibility issues
- due to the change to return type of SD_Simulate. See also:
+ due to the change to return type of SD_simulate. See also:
http://lists.gforge.inria.fr/pipermail/simgrid-user/2010-December/002206.html
* Add new macros with variable number of arguments.
- in xbt/log.h: XBT_DEBUG, XBT_VERB, XBT_INFO, etc.
Define XBT_USE_DEPRECATED if you want to use the old numbered macros like
INFO1, INFO2, etc.
* Change xbt_die() to accept a format string with arguments, just like printf.
- * New data structure: xbt_lib_t, like a dict but more general and with better memory handling.

INSTR
* New configuration options
* XBT logging makes tracing error checks easier, new root log hierarchy: instr
* New TRACE_user_link_variable interface:
User provides the name of the link and the tracing variable to attach to it
- * the declaration of tracing categories must be done after the environment creation
+ * the declaration of tracing categories must be done after the environment
+ creation
* simpler tracing interface, just one way to declare categories
TRACE_category or TRACE_category_with_color, it is up to you
* links in the trace file are again identified by their names
these options generate traces that are suited to gantt-charts, such as the space-time view of Paje
* The experimental option tracing/msg/volume is deprecated
its functionality may be reincorporated if needed
+ * Buffering
+ The tracing generates a trace file with unordered timestamped events,
+ because of the way the core simulator (surf) works. A script available
+ at the tools directory (fix-paje-trace.sh) can be used to put the events
+ in order. We have changed the tracing so it can generate ordered timestamped
+ events in the final trace, but depending on the simulator (and how much time
+ is simulated) that can lead to a huge memory utilization. It is desactivated
+ by default, but it can be activated using the --cfg=tracing/buffer:1 switch.
Build Infrastructure
* Define a SIMGRID_VERSION macro in simgrid_config.h.
* Add a build option -Denable_debug (set to ON by default): when set to OFF,
assertions and verbose/debug logging events are disabled at compile time.
