+ - Introducing two new functions MSG_process_kill() and MSG_process_killall().
+ - It is possible to bound the rate of a communication in MSG with
+ MSG_task_put_bounded() (was already in the previous version but I had forgotten
+ to write it in the changelog).
+ - Bug fix to let GRAS run on top of MSG until we move it directly on top
+ of the SURF.

+ - Various cleanups to the autotools stuff
+ - Begin to move Gras examples to examples/gras/
+ - Let make distcheck work again (yeah!)
+ (documentation)
+ - documentation overhault using doxygen.
+ gtk-doc-tools is dead in SimGrid now.
+ - Automatically extract all existing logging categories, and add the list
+ to the documentation (long standing one, to say the less)
+ (gras)
+ - Cleanup the known architecture table. Reorder the entries to group what
+ should be, and use a more consistant naming scheme.
+ (some of the test dataset are still to be regenerated)
+ - Allow library to register globals on each process just as userdata does.
+ This is implemented using a xbt_dict and not a xbt_set, so we loose the
+ lookup time (for now).
+ Use it in msg and trp.
+ This cleans a lot the internals and helps enforcing privacy of the
+ headers between the gras components.
+ - Reenable GRAS

+SimGrid (2.90) unstable; urgency=low
+
+ Alpha 1 on the path to SimGrid 3
+
+ * It is a long time since the last release of SimGrid. I'm sorry about
+ that but as I had told you, I was rewriting a lot of things. I apologize
+ to those who had been reporting bugs to me and that I had not answered.
+ If your bug is still in the new version, please tell me. Here is a
+ summary of the main changes.
+
+ * REVOLUTION 1: The SimGrid project has merged with the GRAS project
+ lead by Martin Quinson. As a consequence SimGrid gains a lot in
+ portability, speed, and a lot more but you'll figure it out later.
+ SimGrid now comprises 3 different projects : MSG, GRAS and SMPI.
+ I wanted to release the new MSG as soon as possible and I have
+ broken GRAS, which is the reason why, for now, only MSG is fully
+ functionnal. A laconic description of these projects is available
+ in the documentation.
+
+ * REVOLUTION 2: I have removed SG and I am now using a new simulation
+ kernel optimized for our needs (called SURF but only the developers
+ should use it). Hence, MSG is now roughly 30 times faster and I think
+ that by rewriting a little bit MSG, I could event speed it up a little
+ bit more. Beside the gain in speed, it is also much easier to encode a
+ new platform model with SURF than it was with SG. More to come...
+
+ * REVOLUTION 3: I have tried to change a little as possible the API of
+ MSG but a few things really had to disappear. The main differences
+ with the previous version are :
+ 1) no more m_links_t and the corresponding functions. Platforms are
+ directly read from a XML description and cannot be hard-coded
+ anymore. The same format is used for application deployment
+ description. The new format is described in the documentation.
+ Have a look in tools/platform_generation. There is a tiny script
+ that converts from the old platform format to the new one. Concerning
+ the application deployment format, parsing the old one is tricky.
+ I think most of you should hower be able to convert your files. If
+ it is really an issue, I can write a C code that does the conversion.
+ Let me know.
+ 2) the toolbox tbx does not exist anymore. We now have a library
+ with much more data-structures but without the hash-tables (we have
+ dictionaries that are much faster).

+ Version 2.90: "the long awaited one"
+ - Finished rewriting and debugging MSG. Rewrote the documentation.
+ - disable GRAS for now since it needs to be ported to the newest SG
+
+2004-12-16 Martin
+ - Finish the port to windows (using mingw32 for cross-compile)
+
+2004-11-28 Arnaud
+ - Main loop and datastructures of SURF. A cpu resource object is
+ functionnal. Surf can thus be used to create cpu's with variable
+ performance on which you can execute some actions.
+
+2004-11-15 Martin Quinson
+ - Port to ARM. Simply added the alignment and size descriptions. Should
+ work, but the ARM machines are so slow that I didn't had the opportunity
+ to 'make check' overthere yet.

+ - Trace manager now written. It uses a heap structure and is therefore
+ expected to be efficient. It may however be speeded up (particularly
when many events occur at the same date) by using red and black
trees. One day maybe...
- Max-min linear system solver written. It uses a sparse matrix
so I assume that the patch is correct. I do not know however if things
run effectively faster than before now. :)
+ Inclusion of the SimGrid tree in the GRAS one. The archive is renamed to
+ SimGrid, and the version number is bumped to 2.x

They are the result of a RMI/RPC on the remote machine.
