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
+ The Half Release, aka the Zeleous 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 plugins.
+ - 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 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()
+ - 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.
+ - In CMake
+ - option enable_tracing was removed. It was not doing anything since 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.
- 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.
+ - 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)
- 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
MSG
+ * The examples were completely reorganized, 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.
+ 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
+ * 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.
* 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
- 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).
+
+ MC
+ * refactoring and cleanup of the code;
+ * ongoing process to cleanly separate the model-checking algorithms
+ from the code model-checking support.

+SimGrid-java (3.8.1) stable; urgency=low
+
+ * New module: org.simgrid.trace.Trace (SimGrid trace bindings)
+ Warning: all methods are visible, but only some of them are
+ implemented so far. Check the source (src/jtrace.c)
+ for further information.
+ * New module: org.simgrid.msg.File (SimGrid File management functions)
+ * New Module: org.simgrid.msg.VM (SimGrid interface to mimick IAAS clouds)
+ * Change the meaning of Process.restart: now restart the process from
+ the begining, like MSG_process_restart in C.
+ * Add Process.setAutoRestart: handling of process restart when failed
+ host comes back.
+ * Add Process.getProperty, Host.getProperty, Host.getProperty: allows
+ you to retrieve the properties of the processes/hosts
+ * Deprecate Msg.clean(): you can just forget about it now.
+ * New function Process.getCount(), that only works when compiling
+ with the not yet released version 3.9 of the C library.
+
+ * New context factory based on Coroutines. It mandates a modified JVM
+ but then, the simulations run about five times faster, and there is
+ no limit to the amount of processes (beside of the available memory).

SimGrid (3.7.1) stable; urgency=low
MSG:
-- Thu Jun 7 2012 Da SimGrid team <simgrid-devel@lists.gforge.inria.fr>
+
+SimGrid-java (3.7.1) stable; urgency=low
+
+ The "Java aint got to be bloated and slow" release
+
+ Major cleanups:
+ * Various internal cleanups and performance improvement
+ Simulations are expected to run up to twice faster or so
+ * Make Process.kill(process) an instance method, not a static one
+ * User processes are not java.lang.Thread subclasses.
+ This breaks the compatibility (sorry), but previous API was
+ brain-dead, making it impossible to have non-trivial
+ initializations in the process constructor.
+ * Require a full constructor per Process sub-class.
+ Kinda breaks the compatibility (sorry), but this allows a much more
+ efficient way to launch the processes at simulation startup.
+ * Do not embeed our version of semaphores, java 1.5 can be considered
+ as sufficiently prevalent for us to not dupplicate its features.
+ * Lot of bug fixes
+
+ Extend the API:
+ * Add examples for almost every part of the API
+ We spotted and fixed a lot of bugs in the process
+
+ * New module: asynchronous communication API
+ * New function: Process.sleep()
+ It takes milliseconds as argument, just as java.lang.Thread.sleep()
+ * New module: org.simgrid.msg.Mutex (SimGrid mutexes)
+ * New module: org.simgrid.msg.RngStream (RngStreams random generators)
