+SimGrid (3.21) NOT RELEASED (Release Target: September 23. 2018, 1:54 UTC)
-TRACE
- - Change --cfg=tracing/msg/vm to --cfg=tracing/vm as virtual machine
- behavior tracing is no longer limited to MSG
+Tracing:
+ - Rename 'power' and 'power_used' variables into 'speed' and 'speed_used'
+ - New host variable: 'core_count'
+
+XBT:
+ - Remove xbt_os_thread_specific features
+ - Remove portability wrapper to condition variables
+ - Remove xbt_os_thread_yield()
-MSG
- - The deprecation of MSG is ongoing. A lot of functions are now simple
- wrappers on the C API of S4U. All these wrappers (and their S4U counterparts
- can be found in src/msg/msg_legacy.cpp).
+Fixed bugs:
+ - #93: simgrid should not eat --help
+ - #264: Add ptask L07 resource tracing
+ - #271: Dynamic and manual replay of SMPI traces
+ - #279: Breakpoints option uses time deltas instead of absolute time
+ - #282: TIT convertor erase traces when using absolute path in the trace list file
+ - #285: segfault when a s4u actor kills itself with msg process tracing activated
+ - #286: Pajé traces are not exposing the number of cores
+ - #287: Command-line parsing should stop when encountering '--'
-S4U:
- - Introduced new function simgrid::s4u::Host::get_actor_count. This function
- returns the number of actors running on a specific host.
+----------------------------------------------------------------------------
-Plugins:
- - Allow to run the Link energy plugin from the command line with
- --cfg=plugin:link_energy
- - Rename Energy plugin into host_energy
- - Rename Load plugin into host_load
+SimGrid (3.20) Released June 24. 2018
-simix:
- - Add parameter --cfg=simix/breakpoint to raise a SIGTRAP at given time.
- - kill simix::onDeadlock() that was somewhat dupplicating s4u::on_deadlock()
- - Improve performance when handling timeouts of simix synchros.
+The proxy snake_case() release.
+
+S4U:
+ - The whole API is now using snake_case() instead of mixing it with camelCase.
+ Compatibility wrappers in place for one year.
+ - We took the opportunity to increase the consistency of the API.
+ Please report any remaining glitches.
+ - New function simgrid::s4u::Host::get_actor_count:
+ Returns the number of actors running on a specific host.
SMPI:
- - SMPI is now tested with ~45 proxy apps from various sources, with none or
- only minor patching needed: check github.com/simgrid/SMPI-proxy-apps

- Replay: The replay file has been re-written in C++.
- Replay: Tags used for messages sent via MPI_Send / MPI_Recv are now
supported. They are stored in the trace and used when replayed.
by SMPI. They will be copied locally and loaded separately by each process.
Example --cfg=smpi/privatize-libs:"libgfortran.so.3;libscalapack.so".
- Tracing: add tracing for MPI_Start, Startall, Testall, Testany
- - Interception of getopt, getopt_long and getopt_long_only calls to avoid issues
- with internal index optind with multiple processes. Only works if MPI_Init has
+ - Interception of getopt, getopt_long and getopt_long_only calls to avoid issues
+ with internal index optind with multiple processes. Only works if MPI_Init has
already been called.
- - Fortran: SMPI builds a mpi.mod file which should allow use of "use mpi"

syntax without preprocessing tricks.
+TRACE
+ - Change --cfg=tracing/msg/vm to --cfg=tracing/vm as virtual machine
+ behavior tracing is no longer limited to MSG
+ - TIT (Time Independent Traces): We finally support tags. Unfortunately,
+ this means that traces now need to be updated or re-obtained; both Irecv
+ and Isend lines in your traces have now in total 5 mandatory fields:
+ <rankid> <command> <to/from rankid> <tag> <size>
+ To update your traces, it suffices to add a 0 for the tag here.
+ - TIT now also supports waiting for a distinct request via MPI_Wait.
+ Wait/Test now wait for a specific request, not just the last one that was
+ issued. This unfortunately means another update, because we need to
+ identify which request you want to wait for. We do this via the
+ triplet (sender, receiver, tag), which needs to be added:
+ <rankid> <command> <sender> <receiver> <tag>
+ - Actions are now in lower case (e.g., "allReduce" becomes "allreduce").
+ New script simgrid_convert_TI_traces.py: upgrade your TI traces.
+
+MSG
+ - The deprecation of MSG is ongoing (but this should not impact you).
+ Many MSG functions are now simple wrappers on the C API of S4U. If
+ you wish to convert your code to S4U, find the S4U counterparts of
+ your MSG calls in src/msg/msg_legacy.cpp.
+ - MSG can still be used, but won't evolve anymore.
+
+Plugins:
+ - Allow to run the Link energy plugin from the command line with
+ --cfg=plugin:link_energy
+ - Rename Energy plugin into host_energy
+ - Rename Load plugin into host_load
+
+simix:
+ - Add parameter --cfg=simix/breakpoint to raise a SIGTRAP at given time.
+ - kill simix::onDeadlock() that was somewhat dupplicating s4u::on_deadlock()

XBT:
- Config: the C API is now deprecated (will be removed in 3.23), and
the C++ API has been slightly improved.
- #258: daemonized actors hang after all non-daemonized actors have completed
- #267: Linker error on unit_tmgr
- #269: SMPI: tracing of MPI_Wait/all/any broken
- - SMPI: Fix various crashes with combined use of MPI_PROC_NULL and MPI_IGNORE_STATUS
+ - SMPI: Fix various crashes with combined use of MPI_PROC_NULL and MPI_IGNORE_STATUS
