-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/send_is_detached_thres -> smpi/send_is_detached_thresh
+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
- Removed Java kernel plug-ins.
Will be reintroduced after the ongoing major internals reorg.
+ - In MSG
+ - the following functions were removed.
+ They were too specific and should be reimplemented in a generic
+ way, with filter function.
+ - MSG_task_listen_from_host
+ - MSG_mailbox_get_count_host_waiting_tasks
+ - MSG_mailbox_put_with_timeout was removed.
+ Please use MSG_task_send_with_timeout instead.
- In SimDag
- - the SD_application_reinit function was removed. It was a noop for a while.
+ - the SD_application_reinit function was removed. It has been 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_route_get_communication_time => SG_route_get_latency() + amount / SD_route_get_bandwidth()
- SD_workstation_get_computation_time => amount / sg_host_speed()
- In Java
- - VM.setBound(int load) is now VM.setBound(double bound) to meet the MSG semantics. Use VM.getSpeed()*load/100 for the legacy behavior.
+ - VM.setBound(int load) is now VM.setBound(double bound) to meet the MSG semantics.
+ Use VM.getSpeed()*load/100 for the legacy behavior.
- In CMake
- - option enable_tracing was removed. It was not doing anything since a while.
+ - option enable_tracing was removed. It was not doing anything for a while.
+ - In the ModelChecker:
+ - the model-checker now ptraces the model-checked process which means
+ you cannot use a debugger on the latter anymore (we might make this
+ optional in the feature);
+ - removed soft-dirty page tracking;
+ - remove model-checked side snapshot management,
+ MC_snapshot() and MC_compare_snapshot();
+ - keep the MC_cut() function as a stub (it was not really working
+ in the previous release).
+
+ Options:
+ * All options are consistently in kebab-case. Old names are kept as alias.
XML platforms:
* Switch to platform v4 format.
- In <trace_connect>, attribute kind="POWER" is now kind="SPEED".
- In <host> and <link>, attributes availability and state are gone.
It was redundent with state and availability traces, and with peak values.
+ - In <cluster>, attributes availability_file and state_file are gone.
+ It was too complex and unused.
+ - Kill <gpu>. Was not doing anything.
- 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)
MSG_host_* and SD_workstation_* are #define to the sg_host_* ones
MSG
+ * The examples were completely reorganized (in C and Java), for your browsing pleasure.
* 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.
- Every callbacks should be rewritten to that interface at some point.
-
+ All the callback functions should be rewritten to that interface at some point.
+
Surf
* Reorganizing and cleaning the internals all around the place.
SMPI
* Remove old default barrier/bcast buggy algorithms (see #18407)
* Various bug fixes to handle more codes
+ * Remove the need for the --foreground option of smpirun (it is still
+ accepted for backward compatibility).
XBT
* Kill the setset data container: MC don't use it anymore.
* 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.
+ They throw exceptions on invalid input;
+ * C++ support for declaring CLI flags (simgrid::config::Flag);
+ * class for abstracting different signal backends (simgrid::xbt::signal).
+ with no external dependencies (we need very simple signals).
+
+ MC
+ * refactoring and cleanup of the code;
+ * ongoing process to cleanly separate the model-checking algorithms
+ from the code model-checking support.
