The Spring Release: continuous integration servers become green
We fixed even the transient bugs on all target architectures:
- 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: dupplicates MSG_host_get_speed
+ - 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.
- Fix numerous memleaks all around the place. In particular, around VMs.
S4U
event from the availability_file changes the avail speed.
- Links are now usable from s4u
- New: Engine::hostList() and Engine::hostCount(). Still clumsy.
- - Drop Host::getPstateSpeedCurrent() which dupplicates Host::speed()
- - New examples, converted from MSG.
+ - 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
This can break codes using SMPI internals (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)
+ - MPI_Win_lock/unlock, MPI_Get_accumulate 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 small file using some system magic.
- Bugfix: smpirun was sometimes misusing hostfile when wrongly terminated
- A <cluster> can now be created with different speed values to represent pstates.
see examples/platforms/energy_cluster.xml for an example.
