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
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
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
* 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()
+ * 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, 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
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)
+ 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.
* 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
+ * 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
