- - Cleanup the known architecture table. Reorder the entries to group what

+ 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
+ functional. 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 however 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).

- Introduction of the remote errors.
They are the result of a RMI/RPC on the remote machine.
ErrCodes being scalar values, you can't get the host on which those
- errors did happen. Extending the error mecanism as in Gnome is possible.
