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). + + -- Arnaud Legrand Mon, 31 Jan 2005 10:45:53 -0800 -- 2.20.1
