- added relevant logic for everything except mca_coll_basic_reduce_log_intra() -- need some help from George / Edgar on this one... - replaced ompi_ddt_sndrcv() with ompi_ddt_copy_content_same_ddt() where relevant - removed some "if (size > 1)" conditionals, because the self coll module will always be chosen for collectives where size==1 Waiting for BA's tests to check the validity of this IN_PLACE stuff. We'll see how it goes! This commit was SVN r7351.
