SimGrid (3.13) UNRELEASED; urgency=low
The Easter Trim Release.
+
+ Backwards Compatibility breaks
+ - Some command line options were renamed for consistency sake:
+ - model-check/sparse-checkpoint -> model-check/sparse_checkpoint
+ - smpi/async_small_thres -> smpi/async_small_thresh
+ - smpi/send_is_detached_thres -> smpi/send_is_detached_thresh
+
+ - Removed Lua simulation bindings (switch to C or Java for that).
+ Lua can still be used to describe platforms
+ - Removed Java kernel plugins.
+ Will be reintroduced after the ongoing major internals reorg.
+ XML platforms:
+ * Switch to platform v4 format.
+ - Rename from 'power' to 'speed' the attributes describing the amount of
+ flops that a <host>, <peer>, <cluster> or <cabinet> can deliver per second.
+ - In <trace_connect>, attribute kind="POWER" is now kind="SPEED".
+ - The DOCTYPE points to the right URL (this file):
+ http://simgrid.gforge.inria.fr/simgrid/simgrid.dtd
+ (the file at this address now documents the changelog since its v1)
+ - A warning is emitted for unit-less values (they are still accepted).
+ - speed. Default: 'f' or 'flops'. Also defined:
+ 'Yf', 'Zf', 'Ef', 'Pf', 'Tf', 'Gf', 'Mf', 'kf'
+ 'yottaflops', 'zettaflops', 'exaflops', 'petaflops', 'teraflops', 'gigaflops', 'megaflops', 'kiloflops'
+ - bandwidth. Default: 'Bps' bytes per second (or 'bps' for bits but 1 Bps = 8 bps)
+ Also defined in bytes: 'TiBps', 'GiBps', 'MiBps', 'KiBps', 'TBps', 'GBps', 'MBps', 'kBps', 'Bps'
+ 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).
+
S4U
* s4u::Host is now the prefered public interface to the Host features.
sg_host_* functions are C bindings to the exact same behavior
MSG_host_* and SD_workstation_* are #define to the sg_host_* ones
-
+
+ MSG
+ * Kill all deprecated functions (the ones you had when declaring MSG_DEPRECATED).
+ They were deprecated since a few years, and probably did not even compile anymore.
+
Simix
* simgrid::simix::kernel() is the closure callback. It ensures that
the lambda or closure passed as a parameter will run in kernel mode.
* Reorganizing and cleaning the internals all around the place.
SMPI
- * BC breaks:
- - The option smpi/async_small_thres was renamed to smpi/async_small_thresh
- as we attempt to unify our naming schemes -> smpi/send_is_detached_thresh
+ * Remove old default barrier/bcast buggy algorithms (see #18407)
+ * Various bugfixes to handle more codes
XBT
- * Kill the setset datacontainer: it's unused since a while.
- * Kill the queue datacontainer: it made more sense with GRAS.
+ * Kill the setset data container: MC don't use it anymore.
+ * Kill the queue data container: it made more sense with GRAS.
+ * Kill the xbt_peer_t data type: it's useless without GRAS.
+ * New functions:
+ - xbt_dynar_sort_strings(), when the content is char*
+ - xbt_str_parse_int / xbt_str_parse_double, wrapping strtol/strtod
+ They throw exceptions on invalid input.
- JAVA:
- * Remove the ability to write internal plugins in Java.
- It may be reintroduced once the ongoing cleanup is done.
