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 and bypass the XML surf parser
+ * 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
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.pl.
+ 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
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/).
+ 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
* 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)
+ * 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)
GRAS:
* New function: gras_msgtype_get_name()
-
- Build chain: bug fixes and further polishing
+ * 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 (not well tested)
+ '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
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.
