+ S4U
+ - Execution->setHost() can be called after start() to migrate it.
+ - Comm::test_any() is now implemented.
+
+ Fixed bugs:
+ - #245: migrating an actor does not migrate its execution
+
+SimGrid (3.18) Released December 24 2017
+
+ The "Ho Ho Ho! SimGrid 4 beta is coming to town" release.
+
+ MSG IS NOW DEPRECATED. Please use S4U for new projects.
+ - Support for MSG should not be removed from SimGrid before 2020,
+ but future evolutions will be limited to the integration of
+ user-provided patches.
+
S4U New features
- s4u::onDeadlock() signal, run before stopping the simulation.
- s4u::Exec: asynchronous executions (abstraction of background
threads)
+ - s4u::Host->getLoad() returns the achieved speed in flops/s
S4U API changes
- Link::name() is deprecated and will be removed in v3.21, use
name implies on both sequential and parallel tasks.
- Both changes fix GitHub's #223 using PR #237 as a basis.
Thanks Michael Mercier.
+ - Most examples were converted to S4U and hidden elsewhere at tests.
+ Rational: we still want MSG to work; we want newcomers to use S4U.
SURF
- LMM stuff moved to its own namespace: simgrid::kernel::lmm.
- Renamed LMM classes (e.g. s_lmm_system_t -> System).
+ SMPI
+ - Switch to the faster dlopen privatization mechanism by default
+ - Documentation improvments
+
+ Virtual Machines
+ - Live migration is getting moved to a plugin. Dirty page tracking is
+ the first part of this plugin. This imply that VM migration is now
+ only possible if one this function is called :
+ - C/MSG: MSG_vm_live_migration_plugin_init()
+ - C/C++: sg_vm_live_migration_plugin_init()
+ - Java: Msg.liveMigrationInit()
+ For C and C++, "simgrid/plugins/live_migration.h" also has to be
+ included.
+
XBT
- Define class simgrid::xbt::Path to manage file names.
- Removed unused functions:
