SimGrid (3.3.2-svn) unstable; urgency=low
+ The "Simplicity does not preceed complexity, but follows it" release.
+
+ The main contributors of this release were (lexical order):
+ Silas De Munck, Stéphane Genaud, Martin Quinson, Cristian Rosa.
+
SMPI:
* Implement some more MPI primitives:
- MPI_Waitany, MPI_Waitall, MPI_Reduce, MPI_Allreduce
+ 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
+ Scatter: flat tree
* Add support for optimized collectives (Bcast is now binomial by default)
* Port smpirun and smpicc to OS X
- Use dynar to represent routes (instead of void** + int*)
- kill link_set (use surf_network_model->resource_set instead)
- Add a command-line option to choose the routing schema to use
+ - Add three new models:
+ * Floyd (shortest path computed at initialization)
+ * Dijikstra (shortest path recomputed all the time)
+ * Cached Dijikstra (shortest path computed on need)
+ All these models where contributed by Silas De Munck, and are
+ described in his ICCS09 paper.
* Simplify model declaration
(less redirections, less function to write when defining a model)
