- * Improvements for the SMPI replay tool:
- - For most of the collective communications we can know exactly
- which rank is the root one.
- - Now we can include in the traces the real used MPI datatype
- (till know we were using the MPI_BYTE). Also we can have multiple
- datatypes in the traces.
- - The tool supports both time-independent traces from the TAU and the
- modified MPE tools.
- - Fix the Reduce action, as there was no information about computation
- load.
+ * SMPI is now included directly in the libsimgrid as the windows
+ linker dont forces us on splitting it anymore.
+ * Improvements of the SMPI replay tool:
+ - Most of the collective communications are now rooted in the same process as
+ in the original application.
+ - Traces now rely on the same MPI datatype as the application (MPI_BYTE was
+ used until now). Multiple datatypes can now be used in a trace.
+ - The replay tool now supports traces produce either by TAU or a modified
+ version of MPE.
+ - Bug Fix: the compute part of the reduce action is now taken into account.
+ * smpirun generates the hostfile if needed (with given hostcount and platform)
+ * Integration of more than 100 STAR-MPI, mpich, OpenMPI collective algorithms
+ - allows to select one in particular with --cfg=smpi/coll_name:algorithm
+ - allows to use the decision logic of OpenMPI(1.7) or MPICH(3.0.4) by setting
+ --cfg=smpi/coll_selector:(mpich/ompi)
+ * Support for new functions : MPI_Issend, MPI_Ssend, Commutative operations in
+ Reduce
+ * Add a --cfg:tracing/smpi/internals option, to trace internal communications
+ happening inside a collective SMPI call.
+ * Fix the behavior of complex datatypes handling
+ * replace MPICH-1 test suite by the one from MPICH 3.0.4
+ * Add all missing Fortran bindings, SMPI should work with Fortran 90
+ (no privatization of global variables yet)
+
+ SimDag:
+ * Allow to change SimGrid configuration (see --help) within the code
+ thanks to SD_config() as it can be done in MSG.
+ * Add a new function SD_task_set_amount() upon user request.
+
+ PLATFORM:
+ * Handle units for values (10ms, 10kiloflops, 10Bps, 1GB, ...)
+ * Remove rule based routing (no more pcre dependency)
+ * Add a limiter_link option to cluster tag, to specify a maximum reachable
+ bandwidth in fullduplex mode when it is < 2*nominal bw
+ * Add a loopback_bw and loopback_lat options to cluster tag.
