- New function NetZone::add_route(host1, host2, links) when you don't need gateways
Also add a variant with s4u::Link, when you don't want to specify the directions
on symmetric routes.
- - Introduce a Mailbox::get_async() with no payload parameter. You can use the new
+ - Introduce a Mailbox::get_async() with no payload parameter. 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.
+ - 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
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
+sthread:
+ - Implement recursive pthreads.
+ - Many bug fixes.
+
Python:
- Make the host_load plugin available from Python. See examples/python/plugin-host-load
- Mailbox::get_async() does not return a pair anymore. Use comm.get_payload() instead.
Plugins:
- Revamp the battery plugin: rewrite completely the API, for a better usability.
The examples were updated accordingly.
+ - 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.
+Kernel:
+ - optimize an internal data structure (replace boost::circular_buffer_space_optimized by
+ std::deque to store pending and unmatched Comms in Mailboxes). It is actually a revert
+ to what was used a few years back. The boost structure had a lower memory footprint than
+ deques, but it appeared that their "space_optimized" character was generating a huge lot
+ of refcount changes on the stored Comms.
