+
+The "Thanks Giving up stateful model-checking" release. Stateless model checking remains.
S4U:
- New class ActivitySet to ease wait_any()/test_any()/wait_all()
- 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.
+ - Update s4u::create_DAG_from_json() to support wfformat 1.4.
- 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 function: Mutex::get_owner()
-New S4U plugins:
- - Add a JBOD (just a bunch of disks) concept. It's a sort of host with many disks.
+S4U plugins:
+ - New: 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).
- 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.
+ - New implemented calls: MPI_Isendrecv, MPI_Isendrecv_replace
sthread:
- Allow to use on valgrind-observed or gdb-observed processes.
- Comm::waitall/waitany/testany() are gone. Please use ActivitySet() instead.
- Comm::waitallfor() is gone too. Its semantic was unclear on timeout anyway.
- Io::waitany() and waitanyfor() are gone. Please use ActivitySet() instead.
+ - Do not export the values of enums. So you need to write e.g. SharingPolicy.LINEAR
+ while it should have been possible to write LINEAR alone before. This is the advised
+ behavior for modern C++ code.
C API:
- Introduce sg_activity_set_t and deprecate wait_all/wait_any/test_any for
