SMPI:
* Implement some more MPI primitives:
- MPI_Waitany, MPI_Waitall, MPI_Reduce, MPI_Allreduce, MPI_Sendrecv
+ MPI_Bcast, MPI_Waitany, MPI_Waitall, MPI_Reduce, MPI_Allreduce, MPI_Scatter, MPI_Sendrecv, MPI_Alltoall
+ -implementation: Bcast: flat or 2-ary tree (default),
+ Barrier: 4-ary tree,
+ Reduce: flat tree
+ Allreduce: Reduce then Bcast
+ Alltoall: "basic_linear" if data per proc < 3Kb, "otherwise pairwise".
+ Not yet implemented: "Bruck" for data per proc < 200b and comm size > 12
+ Alltoallv: flat tree, like ompi
+ Scatter: flat tree
* Add support for optimized collectives (Bcast is now binomial by default)
* Port smpirun and smpicc to OS X
+ SIMIX:
+ * Relocation of the context module from XBT to SIMIX.
+ (the context were decoupled from the simix processes, duplicating a lot of code)
+ => a lot of code was factorized
+ - less overhead is introduced during scheduling
+ - simpler API for the context factory
+ - the logic for process creation,destruction and manipulation was simplified
+ * Simplification of the s_smx_process_t data structure.
+ => accesing the simix level data associated to a process is faster now,
+ and the code is a lot more readable.
+
SURF:
* Extract the routing logic into its own object.
(was dupplicated in network.c and workstation_LV07.c;
* Add xbt_graph_node_get_outedges() [Silas De Munck]
* Add xbt_str_from_file(FILE*)
* Add xbt_dict_get_key achieving a linear reverse search
-
+ * Remove the context module [Cristian Rosa]
