Hi all, I've compiled mpich-3.1.3 on centos 6.5 with the following options: --enable-fortran=yes \ --with-device=ch3:nemesis:ib \ --with-pm=hydra:gforker \ and the package 'libibverbs-devel' installed. When I try to run a test hello program using two IB DDR nodes, using the command: mpiexec.hydra -np 16 -bind-to core -launcher rsh -iface ib0 -hosts jff201,jff202 mpi_hello I've got the errors bellow, even running using with root user. If I compile with: --with-device=ch3:nemesis it works with no errors. I am also using both openmpi and mvapich2 on Infiniband and they work fine Am I doing something wrong when compiling and/or running? Any sugestion is welcomed? Thanks in advance Regards ########################################################################## MPICH OVER IB: RUN ERRORS ########################################################################## Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(498): MPID_Init(177).......: channel initialization failed MPIDI_CH3_Init(89)...: MPID_nem_init(320)...: MPID_nem_ib_init(264): MPID_nem_ib_com_open failed Fatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(498): MPID_Init(177).......: channel initialization failed MPIDI_CH3_Init(89)...: MPID_nem_init(320)...: MPID_nem_ib_init(264): MPID_nem_ib_com_open failed [root@jff201 mpich]# mpirun -np 2 -iface eth0 mpi_hello-mpich IB device not foundFatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(498): MPID_Init(177).......: channel initialization failed MPIDI_CH3_Init(89)...: MPID_nem_init(320)...: MPID_nem_ib_init(264): MPID_nem_ib_com_open failed IB device not foundFatal error in MPI_Init: Other MPI error, error stack: MPIR_Init_thread(498): MPID_Init(177).......: channel initialization failed MPIDI_CH3_Init(89)...: MPID_nem_init(320)...: MPID_nem_ib_init(264): MPID_nem_ib_com_open failed ########################################################################## -- Ramiro Alba Centre Tecnològic de Tranferència de Calor http://www.cttc.upc.edu Escola Tècnica Superior d'Enginyeries Industrial i Aeronàutica de Terrassa Colom 11, E-08222, Terrassa, Barcelona, Spain Tel: (+34) 93 739 8928 -- Aquest missatge ha estat analitzat per MailScanner a la cerca de virus i d'altres continguts perillosos, i es considera que est� net. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
