the shared memory btl intra-node, whereas your other choice "--mca btl_tcp_if_include ib0" will not. Could this be the problem? Here we use "--mca btl openib,self,sm", to enable the shared memory btl intra-node as well, and it works just fine on programs that do use collective cal

ositively definitely sure to use the specific BTL. assume that the `sm' flag is even included by default. At the end, just for curiosity, as most part of applications show to work with only "openib,self" flags, what "physycally" happen to the "intranode"
