This new model is more realistic than the previous one, so you
should consider redoing your old experiments with this model.
Sorry for the inconvenience.
+
+ Build System:
+ * Introduce the supernovae compilation mode
+ When compiled that way, the whole SimGrid (or almost) is put in a
+ single compilation unit and compiled in one shoot.
+ This is to help gcc which has difficulties to inline stuff from one
+ file into another.
+ The speedup seem to be above 15%, althrough more tests are needed on
+ amd64 to confirm that gain.
MSG:
* Port of MSG's mailbox on top of SIMIX network
- The put/get mechanism was greatly simplified thanks to the new SIMIX module.
+ The put/get mechanism was greatly simplified on the way.
SIMIX:
- * New SIMIX network module
- It provides a rendez-vous point (aka mailbox) based send/recv API to perform
- synchronous communication.
+ * New SIMIX network module. Provides:
+ - Mailbox: rendez-vous mecanism to find with who you want to speak
+ - Synchronous send/recv: easier and hopefully faster since the
+ logic is handled in the maestro process directly now
+ - Asynchronous send/recv: you dreamt of it? It's here now
+ Too bad that nobody cared enough to propagate the change to MSG.
+ * Add semaphores as SIMIX synchronization mechanism.
SimDag:
* new function SD_daxload(char*) to load a DAX file
