That's a point in the routing algorithm, let's avoid wrong simplifications.
MSG
- - New function: MSG_process_yield()
+ - New: MSG_process_yield(). Stop and yield to other processes.
+ - New: MSG_process_daemon(). Daemon processes are automatically killed
+ when the last non-daemon process terminates
+ - New: MSG_process_ref/unref(). Fiddle with the process refcounting.
- Renamed MSG_energy_plugin_init() -> MSG_host_energy_plugin_init()
to make room for the upcoming network energy plugin.
+ - Drop MSG_host_get_current_power_peak: duplicates MSG_host_get_speed
Java
- Ensure that an actor can kill itself with Process::exit()
- Kill the obscure NativeException. Nobody want to survive the issues
it denotes, so use JniException that is a RuntimeException (not to
- be catched explicitely).
+ be caught explicitly).
+ - Partial bug fix in initialization. SimGrid flags on command line were
+ consumed at C level but stayed in the original Java String[] args.
+ This could mess users' args[i] if SG flags were not put at the end of
+ the command line.
+ The SimGrid flags are now removed from the Java arguments. However,
+ the number of arguments REMAINS UNCHANGED. It is then UNSAFE to test
+ if args.length is greater than the number of YOUR OWN ARGUMENTS.
+ It might be if you have --log or --cfg flags in the command line.
S4U
- New callbacks:
- s4u::Host::onSpeedChange: when the pstate is changed, or when an
event from the availability_file changes the avail speed.
- Links are now usable from s4u
+ - New: Engine::hostList() and Engine::hostCount(). Still clumsy.
+ - New: Actor::suspend(), Actor::resume(), and Actor::migrate(new_host)
+ - New examples: The conversion of MSG examples to S4U has begun
+ - Actors: create, kill, migration, and suspend
+ - Applications: master-worker and token-ring
+ - Action replay: communications and storage
+ - Drop Host::getPstateSpeedCurrent() which duplicates Host::speed()
SimDag
- Backwards Compatibility breaks
Macros ensure the backwards compatibility, but you should fix your code
SMPI
+ - Major C++ rewrite ongoing (SMPI used to be C compiled in C++). This can break codes that were using internals of SMPI (from private.h instead of the public smpi.h).
- Bump our claim of support from MPI 1.1 to MPI 2.2. We don't support 100% of
it, but it should be enough. Contact us if not.
+ - MPI_Win_lock/unlock support added (as for all RMA, implementation is naive and probably inaccurate)
- New algorithm for SMPI_SHARED_MALLOC: global, where all blocks are
mapped onto a unique file.
- Bugfix : smpirun was sometimes misusing hostfile when wrongly terminated
- RMA : MPI_Accumulate are applied in correct order, and
MPI_Win_complete or MPI_Win_post shouldn't miss messages anymore.
- Better support for MPI_IN_PLACE
+ - Support for MPI_Win attrs and keyvals.
- Support MPI_Comm_group_create, MPI_Type_size_x
+ - MPI ops should be properly applied to all allowed types
- Replace implementation of MPI_Bcast "scatter followed by rdb allgather"
algorithm by a non failing one from mpich.
XML
- A <cluster> can now be created with different speed values to represent pstates.
see examples/platforms/energy_cluster.xml for an example.
