S4U: + - Introduce a s4u::Disk interface to manage the newly introduced + tag. s4u::Disk is called to supplant s4u::Storage in a near future. It + thus becomes the default resource to execute I/O operations. Examples + and the file system plugin have been modified to use disks instead of + storage elements. Storage can still be used but is doomed to disappear. + Users are thus adviced to update their simulators accordingly. - Barrier::wait returns SG_BARRIER_SERIAL_THREAD for (only) one actor for consistency with pthread_barrier_wait() - Host::get_englobing_zone() returns the englobing netzone - Actor::on_destruction is now called in the destructor Actor::on_termination new signal called when the actor terminates its code. + - Global signals are now part of the Engine: + - on_platform_creation: after config settings, before the XML parsing + - on_platform_created: right after the XML parsing + - on_time_advance: each time the clock advances + - on_simulation_end: after simulation, before cleanups + - on_deadlock: as the name implies. + - C bindings: + - sg_{actor,host,link}_{data,data_set}() now all exist. + Use them to attach user data to the object and retrieve it. + +Models: + - Introduce an experimental Wifi model. It sounds reasonable + according to the state of the art, but it still has to be properly + validated, at least against ns-3 if not against reality. + - Improved the usability of ns-3. Several bugs were ironed out. + - host_energy: Wattage was expressed as 'idle:oneCore:allCores'. + It is now expressed as 'idle:epsilon:allCores' to properly model the + consumption of non-whole tasks on mono-core hosts.
