- Removed Lua simulation bindings (switch to C or Java for that).
Lua can still be used to describe platforms
- - Removed Java kernel plugins.
+ - Removed Java kernel plug-ins.
Will be reintroduced after the ongoing major internals reorg.
-
+ - In SimDag
+ - the SD_application_reinit function was removed. It was a noop for a while.
+ - The ACCESS_MODE of SD_workstation has been removed. This feature was not really usable and should soon be
+ replaced by a more flexible mechanism.
+ - The following functions thus do not exist anymore
+ - SD_workstation_get_access_mode
+ - SD_workstation_set_access_mode
+ - SD_workstation_get_current_task
+ - Basic estimation functions have been removed but can easily be replaced
+ - SD_route_get_communication_time => SG_route_get_latency() + amount / SD_route_get_bandwidth()
+ - SD_workstation_get_computation_time => amount / sg_host_speed()
+
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):
+ - In <host> and <link>, attributes availability and state are gone.
+ It was redundent with state and availability traces, and with peak values.
+ - The DOCTYPE points to the right URL:
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'
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.
+ * s4u::Host is now the preferred 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
* 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.
+ SimDag
+ * The API has been profoundly modified to directly use the core objects instead of redefining its own.
+ SD_Workstation_t and SD_link_t are now sg_host_t and sg_link_t respectively.
+ Some functions have also been renamed for consistency. Backward compatibility is maintained, but users are
+ encouraged to update their codes. A list of the modified functions can be found at the end of
+ include/simgrid/simdag.h
+
Simix
* simgrid::simix::kernel() is the closure callback. It ensures that
the lambda or closure passed as a parameter will run in kernel mode.
SMPI
* Remove old default barrier/bcast buggy algorithms (see #18407)
- * Various bugfixes to handle more codes
+ * Various bug fixes to handle more codes
XBT
* 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.
+ * Kill rm_cb feature of config sets: it was never useful.
+ * Kill graphxml parsing feature. It was not used.
+ * Kill the deprecated code protected by XBT_USE_DEPRECATED
* New functions:
- xbt_dynar_sort_strings(), when the content is char*
- xbt_str_parse_int / xbt_str_parse_double, wrapping strtol/strtod
