You can use the new Comm::get_payload() once the communication is over to retrieve the payload. - Implement recursive mutexes. Simply pass true to the constructor to get one. - - Update of the Task model. Each Task now consists of a dispatcher, a collector - and one or more instances. The parallelism degree of each of these can be set. - Several examples have been added or modified accordingly. + - Simplify the expression of horizontal scaling of Tasks. + - Each Task now consists of a dispatcher, a collector and one or more instances. + - The parallelism degree of each of these can be set. + - Several examples have been added or modified accordingly. - Introduce a new MessageQueue abstraction and associated Mess simulated object. The behavior of a MessageQueue is similar to that of a Mailbox, but intended for control messages that do not incur any simulated cost. Information is automagically transported over thin air between producer and consumer. See examples/cpp/mess-wait +New S4U plugins: + - Add a JBOD (just a bunch of disks) concept. It's a sort of host with many disks. + - Revamp the battery plugin: rewrite completely the API, for a better usability. + The examples were updated accordingly. + The battery can now act as a simple connector (see battery-connector example). + - Revamp of the Photovoltaic plugin: now called SolarPanel and complete rewrite of the API + - Add chiller plugin: enable the management of chillers consuming electrical energy + to compensate heat generated by hosts. + - Add a battery-chiller-solar example combining several plugins to evaluate the amount + of brown energy (from the electrical grid) and green energy (from the solar panel) + during a given computation. + SMPI: - New SMPI_app_instance_join(): wait for the completion of a started MPI instance - MPI_UNIVERSE_SIZE now initialized to the total amount of hosts in the platform + - Memory usage due to SMPI for non-MPI actors greatly reduced. sthread: + - Allow to use on valgrind-observed processes + - Install sthread on user's disk. - Implement recursive pthreads. - - Many bug fixes. + - Add some McMini codes to test sthread further. + +Model checking: + - More informative backtraces on assertion failure.
