SimGrid (3.16) Released June 22. 2017.
The Blooming Spring Release: developments are budding.
SMPI
- New algorithm to privatize globals: dlopen, with dynamic loading tricks
- New option: smpi/keep-temps to not cleanup temp files
- - New option : smpi/shared-malloc-blocksize . Relevant only when global shared
+ - New option : smpi/shared-malloc-blocksize . Relevant only when global shared
mallocs mode is used, allows to change the size of the fake file used
(default 1MB), to potentially limit the number of mappings for large runs.
- Support for sparse privatized malloc with SMPI_PARTIAL_SHARED_MALLOC()
MSG
- New: MSG_process_yield(). Stop and yield to other processes.
- - New: MSG_process_daemon(). Daemon processes are automatically killed
+ - 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()
- Kill the obscure NativeException. Nobody want to survive the issues
it denotes, so use JniException that is a RuntimeException (not to
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.

mapped onto a unique small file using some system magic.
SMPI

consecutive calls by using an adjustment file (see the documentation).
* Fixed computation of timings for MPI_Send, MPI_Recv & possibly also others

smpi/running-power is renamed to smpi/host-speed

- Ignored parameter of vm_create: core_nb, disk_path and disk_size.

Please switch to xbt_dict_new_homogeneous() before this is removed

would have hoped here.
* xbt_os_sem_get_value: unused internally, deprecated on OS X El Capitan
* Option network/coordinates is now useless and should be dropped.

SimGrid (3.13) stable; urgency=low
The Half Release, a.k.a. the Zealous Easter Trim.
-
+
- We removed half of the lines, that were mostly experimental cruft.
v3.12 lasted 286000 lines of code, v3.13 is only 142000 lines
(not counting blanks and comments -- according to openhub.net)
- The internals are now compiled in C++ (and will soon be clean C++)
- - We removed 75 klines of XML, 12 klines of Java, 5 klines of cmake,

59 klines of C, etc. We added only 29 klines of C++ in replacement.

* Backwards Compatibility breaks
- Removed Lua simulation bindings (switch to C or Java for that).
Lua can still be used to describe platforms
way, with filter function.
- MSG_task_listen_from_host
- MSG_mailbox_get_count_host_waiting_tasks
- - MSG_mailbox_put_with_timeout was removed.

replaced by a more flexible mechanism.

- SD_workstation_get_access_mode
- SD_route_get_communication_time => SG_route_get_latency() + amount / SD_route_get_bandwidth()
- SD_workstation_get_computation_time => amount / sg_host_speed()

Use VM.getSpeed()*load/100 for the legacy behavior.
- In CMake
- option enable_tracing was removed. It was not doing anything for a while.
And the same in bits: 'Tibps', 'Gibps', 'Mibps', 'Kibps', 'Tbps', 'Gbps', 'Mbps', 'kbps', 'bps'
- latency. Default: 's' second. Also defined:
'w' week, 'd' day, 'h' hour, 'm' minute, 'ms' millisecond, 'us' microsecond, 'ns' nanosecond, 'ps' picosecond

* bin/simgrid_update_xml can upgrade your files automatically (won't convert unit-less values)
tools/sg_xml_unit_converter.py may help (but it's just a warning and will probably ever be).
