+SimGrid (3.5) unstable; urgency=low
+
+ Checked up to svn r8318 (Mt)
+
+ MSG
+ * Asynchronous communications through the functions:
+ MSG_task_isend/irecv and MSG_comm_test/wait/waitall
+ * New function: MSG_load_platform_script()
+ to make possible using a lua script instead of XML files to set up platforms
+ * New function: MSG_set_function
+ to associate functions to processes, used when bypassing the parser
+ * New functions: MSG_task_set_name(), MSG_task_set_compute_duration()
+
+ LUA Bindings
+ * Add layer to set up environment directly from lua, without XML
+ * In GRAS, the effect of gras_stub_generator can be achieved through
+ lua too (check examples/gras/console/ping_generator.lua)
+ * Modify the entry point, to take into consideration when lua is used only as a platform generator
+
+ SURF
+ * Change the XML format. This is a very important modification. SimGrid
+ 3.5 introduces a new hierarchical format based on the notion of
+ Autonomous Systems. Compatibility with old format is ensured
+ through the perl script provided in the install bin directory
+ bin/simgrid_update_xml.
+ It is now possible to build platforms with specific routing
+ mechanism (Full/Dijkstra/DijkstraCache/Floyd) and to easily
+ connect several platforms together. We will try to provide soon
+ set of realistic platforms exploiting these properties (have a
+ look at examples/platforms/ for the moment).
+ * Add a new routing scheme (rule-based) using regular expressions. It
+ enables to have an extremely low memory footprint when the
+ underlying routing is simple and can be compactly described. You
+ need to have libpcre4-dev (perl regular expressions) installed if
+ you want to use this routing scheme.
+ * Revive the cluster TAG and allow to easily and efficiently (both in
+ term of memory and speed) connect clusters together. Have a look
+ at teshsuite/simdag/platforms/ to see how this can be done. With
+ this tag, you can create clusters with thousands of tasks at no
+ cost (have a look at examples/platforms/).
+ Note: clusters are implemented as ASes, so there is no need for an
+ enclosing AS tag if you have only one cluster in your platform.
+ * Add new callbacks to the CPU & netwok models to create resources
+ no need to pass through the parser callbacks to do so.
+ * Add new function to create routes table via the routing model
+ * Add generic functions in the public interface that allows the user to
+ call SURF 'create_resource' methods from a lua script.
+ * Add a new model (enabled through command line --cfg=network/model:SMPI)
+ that uses a piecewise linear approximation to produce better
+ results when exchanging small messages.
+ * Add a new parameter to handle correctly full duplex link and account
+ for interferences between uplink and downlink communications
+ (activate with --cfg=fullduplex:1).
+
+ SIMIX
+ * New function: SIMIX_process_set_function() called by MSG_set_function
+ * Change the underlying waiting queue in semaphores so that a process
+ can wait on several of them simultaneously (as in waitany).
+ * Fix the way to handle tokens in semaphores so that all access patterns
+ work: {acquire, acquire_timeout, waitany} / {release, release_forever}.
+
+ SIMDAG
+ * Fix a bug in the management of tasks of size 0 in the surf network
+ models. This problem was only visible with SIMDAG and you should
+ thus disregard results produced with earlier versions if you
+ relied on this feature (some tasks were blocked because of this).
+ * Fix a bunch of stuff that prevented to use classical models with SIMDAG
+ even though your applications were doing only point-to-point
+ communications and sequential computations. Now you can really use any
+ model you want (of course, if you create real parallel tasks, which are
+ not implemented in most models beside ptaskL07, this will abort).
+ * Change the way a task is considered as ready. Instead of removing
+ dependencies when a task is done, a counter is decreased. This way,
+ it is always possible to reach ancestors thanks to the
+ SD_taks_get_parents function (even after the end of the simulation.)
+ * Change the level of some logs in sd_global from INFO to VERB. The
+ corresponding tests are now less verbose
+ * Change the return type of SD_Simulate from (SD_task_t*) into
+ xbt_dynar_t. This function was in handling a dynar internally and
+ converted it into a NULL terminated array for historical reasons.
+ * Rename the SD_READY (all dependencies are satisfied and task is
+ scheduled) state in SD_RUNNABLE and define a new SD_SCHEDULABLE (all
+ dependencies are satisfied) state.
+ This prevents a confusion between the notion of "ready to schedule"
+ (SD_SCHEDULABLE) used in DAG scheduling and that of "ready to be
+ simulated" (SD_RUNNABLE) used by the simulation kernel.
+ * Add an example that scheduling a DAX on an heterogeneous platform
+ using a Min-Min strategy
+ * new function SD_dotload(char*) to load a DAG described in dot
+ format. This loader and the corresponding examples require the
+ installation of the graphviz library.
+ * new function SD_workstation_get_current_task()
+
+ XBT
+ * New data container: setset (set of sets of elements)
+ * New module: mmalloc (mapped malloc, allowing to have several
+ independent segments of malloc)
+ * New function: xbt_dict_cursor_set_data()
+ * New function: xbt_dynar_sort()
+ * New function: xbt_dynar_is_empty()
+ * New function: xbt_fifo_get_last_item()
+ * Bug fix in xbt_dynar_shrink(): use the right element size
+ * Multiple bug fixes in semaphores which were wrongly implemented
+ * Use library init/fini functions for our initialization.
+ - you can use logs and other feature as soon as you want in your
+ code (even before the xbt_init / MSG_init)
+ - xbt_exit is now a no-op and produce a warning when used.
+
+ GRAS:
+ * New function: gras_msgtype_get_name()
+ * Implement gras_agent_spawn in RL too (the prototype changed a bit)
+ * Port GRAS to new SIMIX deployments. This allows gras users to
+ benefit from the lastest improvement to the simulation kernel.
+ * Kill measurement sockets for now. If you rely on them, sorry. This
+ release is not for you. This feature will be reintroduced in the
+ future, but we cannot delay the release any further.
+ * Finally fixed the pmm example. It should not randomly fail anymore
+
+ SMPI
+ * New Model SMPI (three-interval linear regression for correction factors)
+ * New functions:
+ - MPI_Get_count()
+ * New: RAM folding (see RR-7426, http://hal.inria.fr/inria-00527150)
+ and examples/smpi/NAS/DT-folding/
+ * New feature: execution sampling (see RR-7426)
+
+ Build chain: bug fixes and overall polishing
+ * Fix the 'make install' target.
+ No need to use 'make install-simgrid' anymore
+ * Introduce a 'make dist' target compiling a *source* archive
+ 'make package' compiles a binary archive
+ * Compile java files only on need
+ * Add --cd and --setenv command line options to tesh
+ * Port to windows
+ * Out of source builds are not supported yet
+
+ Platforms: Add some more examples in examples/platforms
+ * Grid'5000: see www.grid5000.fr
+
+ Tracing:
+ * Tracing system
+ - tracing API for MSG changes: TRACE_start has no
+ longer parameters, the trace file is supplied through
+ an option passed to simulator. Categories declaration
+ and utilization remain the same. The following options
+ are supported:
+ --cfg=tracing/filename:msg.trace
+ --cfg=tracing/platform:1 (categorized resource use)
+ --cfg=tracing/msg/task:1 (task creation)
+ --cfg=tracing/msg/process:1 (process creation, migration)
+ --cfg=tracing/msg/volume:1 (volume of msg send/recv)
+ --cfg=tracing/smpi:1 (smpi interface tracing)
+ - examples of examples/msg/tracing updated
+
+ * Tracing the MPI interface implemented by SMPI
+ - Collective operations are traced with states
+ - Point-to-Point operations are traced with states/links
+ - Tracing activated by a parameter "-trace filename" passed
+ to smpirun during execution (considering that simgrid
+ is compiled with tracing enabled)
+ - To run the simulation with gdb, the simulator
+ accepts --cfg=tracing/smpi:1 to trace SMPI
+ - tesh files to check if smpi tracing is ok
+
+ * GTNetS tracing re-worked
+ - adaptation to the tracing system of GTNets to cope
+ with modifications regarding the fullduplex mode
+ - new tesh files to check if gtnets tracing is ok
+
+ * New feature to any SimGrid-based simulator: Model-Checking
+ Check SIN#1 for more details.
