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
XBT:
* New function: xbt_dynar_dopar(dynar,fun) to map a function over the
dynar with one separate thread per value of the dynar.
+ * Change the prototype of xbt_thread_create(), sorry.
+ Added a boolean parameter indicating whether we want to join this
+ thread (used in SG only for now)
+ * Implement xbt_thread_join and xbt_thread_yield in SG also.
Bug fixes:
* GTNetS wrappers should now be usable again (and betterly tested too)
- paths to the external world is still rather broken
- the <route:multi> tag is just broken. Actually that's brain-dead.
We need sth like <route:multi src="myCluster" dst="$*-${myCluster}">
- to make it less stupid
+ to make it less stupid
+ ** Check your platform with teshsuite/simdag/platforms/flatifier **
* Fix a source-level compatibility glitch from 3.2: after defining
MSG_USE_DEPRECATED, you can use the old name
MSG_task_put_with_time_out() for MSG_task_put_with_timeout()
* Allow to compile from the SVN with automake 1.11
* Fix some problems when using the "start_time" tag in deployment XMLs.
+ * Fix #8569: XBT/synchro.h has redundant declarations
+ * Fix #8563: MSG return values and exceptions
+ Introduce a MSG_TIMEOUT_FAILURE return code and use it consistently.
+ * Integrate patch #8636: Obey DESTDIR when installing documentation.
+ Thanks to Robson Peixoto.
+ * Fix a vicious bug in dictionaries inducing that some elements were
+ not freed on xbt_dict_free()
