Jelena Pjesivac-Grbovic 568477ade8 Adding new Allreduce algorithms, updating allreduce decision function, and cleaning up util. - Allreduce algorithms: - Recursive doubling is used for small messages (up to 10KB) and can be used for both commutative and non-commutative operations. Recursive doubling passed OCC, IMB-3.2, Intel (Allreduce_c, Allreduce_loc_c, and Allreduce_user_c), mpi_test_suite (Allreduce MIN/MAX, and Allreduce MIN/MAX with MPI_IN_PLACE) tests on TCP up to 36 nodes and MX up to 64 nodes. - Ring algorithms performs well for larger messages but cannot be used for non-commutative operations. It passed the same tests as recursive doubling, except some of the non-commutative tests in Intel benchmarks Allreduce_loc_c and Allreduce_user_c (which was expected). - MPI_Allreduce with new decision function passed all of the tests mentioned above. - Cleaning up coll_tuned_util. Moving isendrecv to static inline just like sendrecv. This commit was SVN r13252.		2007-01-23 01:19:11 +00:00

attribute	Complete next round of message size reduction: "strip" the descriptive info from the returned values.
