SimGrid (3.5) unstable; urgency=low
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
* 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 contrib section of the
- svn. [PIERRE GIVE THE PATH]
+ 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).
+ * Take the opportunity to be a good XML citizen: rename link:ctn to
+ link_ctn and similar changes (also dealed with by simgrid_update_xml)
* 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
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
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}.
+ * kill the dirty pimple SIMIX_message_sizes_output()
+ Please use (proper) visualization instead
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
* 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() that returns the kind
+ of task currently running on a workstation in the sequential access
+ mode.
+ * Task rate should be -1 by default
+ Using 0 as before caused TCP_gamma bound to be ignored.
+ This change modifies (fixes) almost every simdag timings.
+ * Raise some warnings when unexecuted remains at the end of the
+ simulation. This is usually caused by cycles in the DAG.
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 functions: xbt_dynar_sort(), xbt_dynar_compare()
* 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)
+ See RR-7426, available at http://hal.inria.fr/inria-00527150
+ * Ability to use fortran MPI code (through f2c, automatically privatized)
+ * New MPI functions supported: MPI_Get_count(), MPI_Comm_split()
+ * New: RAM folding (see RR-7426 and examples/smpi/NAS/DT-folding)
+ * New: execution sampling (see RR-7426 and examples/smpi/NAS/EP-sampling)
+ * See also src/smpi/README
+
+ 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 fully supported yet, but we are close
+ * Enable supernovae and optimization flags by default for our users
+ * Cmake is now stable enough so that we killed the autotools
+
+ Platforms: Add some more examples in examples/platforms
+ * Grid'5000: see www.grid5000.fr
+ * *_30000_hosts.xml: various huge files [mainly scalability testing]
Tracing:
* Tracing system
- 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
+ - See examples/smpi/NAS/DT-trace
* 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.
