but, what if one wants to work with the second ib I/F (or with the third)? If in automatic way i will create a dat.conf that will have the following lines (on a machine with 2 HCAs, 2 port in each HCA): OpenIB-cma u1.2 nonthreadsafe default /usr/lib/libdaplcma.so mv_dapl.1.2 "ib0 0" "" OpenIB-cma0 u1.2 nonthreadsafe default /usr/lib/libdaplcma.so mv_dapl.1.2 "ib0 0" "" OpenIB-cma1 u1.2 nonthreadsafe default /usr/lib/libdaplcma.so mv_dapl.1.2 "ib1 0" "" OpenIB-cma2 u1.2 nonthreadsafe default /usr/lib/libdaplcma.so mv_dapl.1.2 "ib2 0" "" OpenIB-cma3 u1.2 nonthreadsafe default /usr/lib/libdaplcma.so mv_dapl.1.2 "ib3 0" "" In this file, there is a dapl provider name for every IPoIB I/F, and still there is a default entry (the first I/F). Is this is usefull?
