SimGrid (3.1.1) unstable; urgency=low
- *
+ GRAS:
+ * New module mecanism where user code can use per process globals [Mt]
+ This is similar to gras_userdata_*() functions, but for libraries. It
+ factorize some code developped over and over in the examples and AMOK.
+ It has still to be documented and used (only amok/peermanagement is
+ converted for now).
+ * Fix a vicious bug in the TCP buffering mecanism which leaded to message
+ loss when they were small enough to fit into the buffer and sent quickly
+ enough so that they can all get received in one shoot.
+ * gras_datadesc_by_name and gras_msgtype_by_name: now raise an exception
+ if not found. Use the *_or_null() variant for the old semantic.
+
+ AMOK:
+ * Do really rename the hostmanagement module to peermanagement. [Mt]
+ Ie, rename functions from amok_hm_* to amok_pm_*. This breaks the API,
+ but this is rather new and this was documented in the module
+ documentation (poor excuses, I admit)
+
+ SIMDAG:
+ * A sequential mode has been added to the workstations. When a workstation
+ is in sequential mode, it can execute only one task, and the other tasks
+ are waiting in a FIFO. [Christophe Thiery]
+
+ SURF:
+ * The KCCFLN05 workstation model now handles parallel tasks. It is the
+ model for SIMDAG. [Christophe Thiery]
+ * Bug fix in the maxmin solver: Some values were close to 0 instead of
+ equal to 0, which caused some bad behaviors in
+ saturated_constraint_set_update. I now use a threshold mechanism like in
+ surf. [AL]
+
+ XBT:
+ * When running manually src/testall, you select specific units [Mt]
+ testall is the result of our cunit mecanism, and should replace all
+ the scripty thingy around since bash don't run easily on billware.
+
+ * A mallocator system has been added. [Christophe Thiery]
+ Mallocators allow you to recycle your unused objects instead of freeing them
+ and allocating new ones.
+
+ Documentation update:
+ * FAQ reworking + New FAQs:
+ - "Valgrind spits tons of errors!" [Mt]
+ - "How to repport bugs" [Mt]
+ - "Cross-compiling a Windows DLL of SimGrid from Linux" [Mt]
+ - Communication time measurement within MSG [AL]
+ - I experience weird communication times when I change the latency [AL]
+ * GRAS tutorial [Mt]
+ It contains:
+ - an introduction to the framework and to the used communication model
+ - an initiatic tour introducing the most proheminent features:
+ # Part 1: Bases
+ . Lesson 0: Installing GRAS
+ . Lesson 1: Setting up your own project
+ # Part 2: Message passing
+ . Lesson 2: Exchanging simple messages
+ . Lesson 3: Passing arguments to the processes (in SG)
+ . Lesson 4: Attaching callbacks to messages
+ . Lesson 5: Using globals in processes
+ . Lesson 6: Logging informations properly
+ . Lesson 7: Using internal timers
+ . Lesson 8: Handling errors through exceptions
+ . Lesson 9: Exchanging simple data
+ More are due, of course. They will come latter. In the meanwhile, you can
+ check the examples which are still here.

module that enabled to play with Directed Acyclic Graphs. It is built
directly on top of SURF and provides an API rather close to the old
SG. Some old codes using SG are currently under rewrite to check that
- all needful functions are provided. [Christophe Thiery]
