-SimGrid (3.17) UNRELEASED (release target: September 22 2017)
+SimGrid (3.18) NOT RELEASED YET (target: December 24 2017)
S4U
- - Comm.detach(): start and forget about asynchronous emission
+ - Link::name() is deprecated and will be removed in v3.21, use
+ Link::getCname() instead.
+ - Mailbox::getName() changed to return a std::string, use
+ Mailbox::getCname() instead to get a char*.
+ - Storage::getName() changed to return a std::string, use
+ Storage::getCname() instead to get a char*.
+ - simgrid::s4u::allStorages() becomes
+ simgrid::s4u::getStorageList(whereTo) to have both allocation
+ and deallocation of the map in user space.
+
+ MSG
+ - Deprecate MSG_task_get_flops_amount(). Its semantic was weird:
+ before the start it returned the total amount of flops;
+ after it returned the ratio of remaining work. Split it:
+ MSG_task_get_initial_flops_amount() for first behavior
+ MSG_task_get_remaining_work_ratio() for the second one.
+ This fixes GitHub's #223 using PR #237. Thanks Michael Mercier.
+
+ SURF
+ - LMM stuff moved to its own namespace: simgrid::kernel::lmm.
+ - Renamed LMM classes (e.g. s_lmm_system_t -> System).
+
+ XBT
+ - Define class simgrid::xbt::Path to manage file names.
+ - Removed unused functions:
+ - xbt/file.h: xbt_basename(), xbt_dirname(), xbt_getline()
+ - xbt/graph.h: xbt_graph_edge_get_length(), xbt_graph_edge_set_length,
+ xbt_graph_export_graphviz()
+ - xbt/str.h: xbt_str_join()
+ - xbt/heap.h: use std::priority_queue or boost::heap instead
+ - xbt/swag.h: use boost::intrusive::list instead
+
+ PLUGINS:
+ - New link_energy plugin for the consumption of the links.
+ - All of the operations on files and storage contents have been
+ packaged into a plugin (src/plugins/file_system). The current
+ public interface can be found in
+ include/simgrid/plugins/file_system.h
+ To use these functions you now have to initialize the plugin by
+ calling MSG_storage_file_system_init() just after calling
+ MSG_init() or sg_storage_file_system_init() just after creating
+ the Engine.
+
+ XML
+ - Remove the undocumented/untested tag <include>
+
+ TRACE
+ - Remove viva specific tracing as the tool is no longer maintained
+
+ Fixed bugs:
+ - #248: Kill of finished MSG processes leads to segfault
+
+SimGrid (3.17) Released October 8 2017
+
+ The Drained Leaks release: (almost) no known leaks despite the tests.
+
+ Even very long simulations will preserve your memory: our testsuite
+ stresses SimGrid for over 45mn on fast machines for a coverage of
+ over 80%, and there is only one single known leak, of about 4kb.
+
+
+ S4U
+ - Comm.detach(): start and forget about asynchronous emission. A cleanup
+ handler may be given to free resources if the comm cannot be completed.
- this_actor::send(mailbox) is now mailbox->put()
- New: simgrid::s4u::Comm::wait_all()
- New: Host.execute() for remote executions.
- Deprecate MSG_task_isend_with_matching(): This unused feature
really complicates our internals. Will be removed in v3.20.
+ Simix
+ - Improved context termination. It is now possible to free resources, even
+ when a process is forcibly killed.
+ - ContextBoost: add support for Boost versions above 1.61.
+
+ XBT
+ - Bring back run-time option --cfg=exception/cutpath to remove exception
+ backtraces.
+ - Removed unused functions:
+ - xbt/str.h: xbt_str_split_str(), xbt_str_subst(), xbt_str_ltrim(),
+ xbt_str_rtrim(), xbt_str_trim().
+ - xbt/xbt_os_thread.h: xbt_os_thread_cancel(), xbt_os_thread_detach().
+
+ Misc
+ - Removed header files obsolete since SimGrid 3.12:
+ msg/datatypes.h, msg/msg.h, simdag/datatypes.h, simdag/simdag.h.
+ - Fix many bugs:
+ - #3: SD_exit should be made optional
+ - #120: Memory leak when the processes are forcefully killed
+ - #159: Threading test regression in Actor refcounting
+ - #170: simgrid::s4u::Comm::wait_any() returns too many comms
+ - #185: simgrid::s4u::Engine::instance()->shutdown() segfaults
+ - #186: Actor::killAll() segfaults if some process is blocked on wait()
+ - #191: VM migration and pstate
+ - #192: Updating the energy consumptions of all hosts crashes with VMs
+ - #195: All actors have PID=0 in the logs
+ - #204: Sometimes segfault with thread contexts and mmap privatization
+ - #222: Actor::kill() doesn't really kill and segfaults
+ - #225: Actor::kill() doesn't really kill when victims are doing a join()
+
+----------------------------------------------------------------------------

SimGrid (3.16) Released June 22. 2017.
The Blooming Spring Release: developments are budding.
When one wants to get the list of tasks whose states have changed during a
simulation round, s/he has to allocate and free a dynar and use it as
argument to this function. The former SD_simulate (double how_long)
- now returns void.
+ now returns void.
Virtual Machines
- Allow multicore VMs, with the correct sharing (unless you overcommit)
