-SimGrid (2.91) unstable; urgency=low
-
- * Bug fix in the lmm_solver.
- * Interface to Paje (see http://www-id.imag.fr/Logiciels/paje/) through the function
- MSG_paje_output.
- * 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).

-SimGrid (2.90) unstable; urgency=low
-
- * 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).
