-SimGrid (3.7.1) NOT RELEASED; urgency=low
+SimGrid (3.9) NOT RELEASED; urgency=low
- (to complete)
+ The Grasgory release: GRAS is really dead now.
+
+ GRAS:
+ * If you use GRAS, you should stay at SimGrid 3.5 (at most) since it
+ was considered as experimental and badly maintained since then.
+ * Keeping it was thus a trap to our potential users, that could take
+ it instead of MSG or SMPI by mistake despite is pity state.
+ * GRAS seems to have very few users (if any), and no one volunteered
+ to maintain it further. It also induces a lot of XBT code (for
+ portability sake), that must be maintained too.
+ * For all these reasons, we killed GRAS. If someone wants to revive it
+ in the future, don't cry, our git history still remembers of GRAS.
+
+ SMPI:
+ * Now works on Windows too!
+ * Much more extensive test suite, from MPICH
+
+ MSG:
+ * New function: MSG_process_get_number()
+
+ SURF:
+ * Change the default value of the TCP_gamma constant (maximal size of TCP
+ congestion window) to a more realistic 4MiB value. If you notice changes in
+ your simulation results, you can fall back to the previous 20k tiny window
+ by adding --cfg=network/TCP_gamma:20000 on command line.
+
+ XBT:
+ * Kill synchronized dynars, and xbt_dynar_dopar(). We cannot think of a
+ usecase where it's really mandatory, and maintaining it was a pain in
+ our codebase.
+ * New: xbt_fifo_search(), search an item with a user-provided
+ comparison function instead of dumb pointer comparison.

+SimGrid (3.8.1) stable; urgency=low
+
+ The "we are told that some people want to also *install* the simgrid
+ framework" release.
+
+ * Add missing file "tesh.1" to the archive.

+
+SimGrid (3.8) stable; urgency=low
+
+ The Psssshiiiit release: SimGrid jumps into the Cloud.
+
+ MSG:
+ * Add an experimental interface to manipulate VMs. They are mainly
+ process groups with very few intrinsic semantic, but they should
+ allow you to build the semantic you want easily.
+ * New function: MSG_host_set_property_value()
+ * New function: MSG_process_on_exit(). To clean memory in all cases.
+ * Bug fixes that made the host (and link) failures unusable.
+ * Add a way to auto-restart process when the host in which they are
+ executing comes back (ON_FAILURE="RESTART" on deployment file,
+ MSG_process_auto_restart_set).
+ * Use the "msg_" prefix for all datatypes (instead of m_, msg_ and MSG_),
+ please stop using the old ones, they are DEPRECATED.
+
+ * Deprecate functions MSG_global_init() / MSG_global_init_args()
+ Please use MSG_init() instead. (reducing the amount of entry
+ points in the library helps us).
+ * Make it impossible to link against the wrong version of the lib
+ * Deprecate MSG_clean(). No need to call it anymore.
+ * Function MSG_get_host_number() is not deprecated anymore.
+
+ Documentation:
+ * Split the doc into a user guide and a reference guide.
+ * Start a developper guide to help people hacking on SimGrid.
+
+ Cmake:
+ * Enable tracing by default. This modules rocks you should use it.
+ * Remove option custom_flags. Now use environment variables CFLAGS
+ and LDFLAGS.
+ * Use default cmake things to detect lua instead of home grown ones.
+ * New option "enable_mallocators" to disable mallocators, for debugging
+ purpose ("on" by default).
+
+ Simix:
+ * Bug fixes around the resource failures: don't let the processes
+ survive the host they are running onto.
+ * Add an interface to auto-restart processes when the host in which they are
+ executing comes back.
+ * Ensures that SIMIX_clean is called automatically. It's not part of
+ the public interface anymore (bindings should be updated).
+
+ SimDag:
+ * Bug fix for when SD_Simulate is called with a positive value: be careful
+ when comparing doubles. Sometimes they are different for non significant
+ digits only.
+ * New types of typed tasks. SD_TASK_COMP_PAR_AMDAHL represents a
+ parallel task whose initial work is distributed among host according
+ to the Amdahl's law. Such tasks are created with a parameter alpha
+ that corresponds to the non-parallelizable part of the computation.
+ SD_TASK_COMM_PAR_MXN_1D_BLOCK represents a complex data redistribution
+ between two sets of workstations assuming a 1D block distribution (each
+ workstation owns a similar share of data) on both sides.
+
+ These tasks can be scheduled with SD_task_schedulel or SD_task_schedulev.
+ Data redistribution will be automatically scheduled once parent and child
+ are both scheduled. The filling of computation_amount and
+ communication_amount structures is now done seamlessly thanks to the chosen
+ assumptions.
+ * New function SD_workstation_dump to display various information
+ * New function SD_task_set_rate to throttle the bandwidth allowed to be used
+ by a SD_TASK_COMM_E2E typed task. This rate depends on both the nominal
+ bandwidth on the route onto which the task is scheduled and the amount of
+ data to transfer.
+ To divide the nominal bandwidth by 2, the rate then has to be :
+ rate = bandwidth/(2*amount)
+ * Compute tasks that have failed can now be rescheduled and executed again
+ (from their beginning)
+ * Increasing source code coverage (src/simdag is now covered at 95.8%
+ on average)
+
+ SMPI:
+ * Re-implement time-independent trace replay using SMPI (at the
+ smpi_smp_* level) instead of MSG. This should replace
+ examples/msg/actions/actions.c
+ * Implement support of MPI Datatypes (vectors, hvectors, indexed,
+ hindexed and structs)
+ * Implement the exchange of non-contiguous data.
+ [Khalid Hasanov & Jean-Noel Quintin] Thanks for the patch, guys.
+ * Correct behavior of smpi/sender_gap and set its default value to 0
+ * Add option to asynchronously send small messages to allow better
+ simulation of pt2pt communications. --cfg=smpi/async_small_threshold:value
+ specifies the size in bytes under which messages will be asynchronously sent.
+ * Add support of MPI_Iprobe, MPI_Probe, MPI_Testall, MPI_Wtick functions
+ * SMPI now handles more MPI specific values in input. Closes [#14389] and [#14388]
+
+ SimGrid:
+ * New C interface to define a platform: XML is now optional.
+ For more info, please check include/simgrid/platf.h.
+ * New interface to define random platforms from the C:
+ For more info, please check include/simgrid/platf_generator.h and
+ examples/msg/masterslave/masterslave_platfgen.c
+ * Export a sg_cmdline dynar containing all the arguments we got from
+ the command line.
+
+ TRACE:
+ * Two new tracing options for adding comments to trace file so you
+ can track your experiments (see --help-tracing for details).
+ * New option to generate a impoverished trace file (--cfg=tracing/basic:1)
+ * Adding the SimGrid version that generated the trace file as a comment.
+ * Instrumenting other MSG functions (MSG_task_isend_with_matching and MSG_task_dsend)
+ * Fix to avoid key clashes on Paje links
+ * Other minor fixes related to the Paje specification
+
+ XBT:
+ * Functions xbt_dict_hash() and xbt_dict_hash_ext() are made public,
+ and renamed to xbt_str_hash() and xbt_str_hash_ext().
+ * New function: xbt_os_timer_resume() to restart a timer w/o resetting it.
+ * Greatly improve the robustness of mmalloc to user errors (such as
+ using an area after freeing it, or freeing it twice)

+SimGrid (3.7.1) stable; urgency=low
+
+ MSG:
+ * Restore the prototype of MSG_process_create_with_environment() to
+ the pre-3.7 situation by removing the kill_time argument.
+ * Add a MSG_process_set_kill_time() function instead.
+
+ SURF:
+ * Fix weird behaviors when dealing with parallel tasks.
+
+ WINDOWS:
+ * Simgrid is now built as a dll.
+ * Simgrid-java now works on Windows.
+ * Simgrid-Java is now included into Windows package.
+
+ MacOS:
+ * First pre-build package for MacOSX.
+
+ Build System:
+ * Fix compilation when using MSG_USE_DEPRECATED.
+ * Fix some compilation issues on Macs and Windows.
+ * Reduce the number of failing tests on exotic systems, like Debian/Hurd.
+ * Environment variables CFLAGS and LDFLAGS are now honored by cmake.
+
+ We discovered that the Lua console is broken, but we are missing the
+ manpower to fix it right now. The problem existed in 3.7 too, so we
+ are not blocking the release for that. Sorry if you depended on this
+ feature, any help would be really welcome.

The "spring cleanups (before the next Big Project kicks in)" release.
- Add new runtime parameters --help-logs and --help-log-categories
to display informations about supported logging parameters and
categories.
- - Old deprecated parameters --{gras,surf,msg.simix,xbt}-log=...
+ - Old deprecated parameters --{gras,surf,msg,simix,xbt}-log=...
don't exists anymore.
* Mallocators: allow value NULL for the reset function.
* Dicts:
[contributed by Sékou Diakite, many thanks]
GRAS:
- * Introduce a listener thread in charge of receiving incomming
+ * Introduce a listener thread in charge of receiving incoming
messages from the network. It allows to overlap communication and
computation but most notably, it removes some stupid deadlocks due
to the fact that so far, a process could not send and receive at
[Tests]
- use gras_exit in example to track memleaks
- get rid of gs_example now that GS is properly integrated into gras
- - update run_test to integrate the lastest tests (datadesc)
+ - update run_test to integrate the latest tests (datadesc)
[Logging]
- rename WARNINGn macros to WARNn since it prooved error-prone
