I've tried waht you told me and made some tests: cluster master machine eth0 mpihosts_out --> for outside use (getting its own ip via dhcp) eth1, mpihosts_cluster --> for cluster use (serves ip's to cluster nodes) ------- TESTS 1,2 -openmpi-1.0.2a9 ------ 1.- cd openmpi-1.0.1 2.- make clean 3.- cd openmpi-1.0.2a9 4.- ./configure 5.- make all install no parameters /usr/local/etc/openmpi-mca-params.conf mpirun -np 2 --hostfile mpihosts_cluster ping_pong mpirun -np 2 --hostfile mpihosts_out ping_pong GIve the same results: Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR) Failing at addr:0x6 *** End of error message *** [0] func:/usr/local/lib/libopal.so.0 [0x40101cb2] [1] func:[0xffffe440] [2] func:/usr/local/lib/openmpi/mca_btl_tcp.so [0x404541d6] [3] func:/usr/local/lib/openmpi/mca_btl_tcp.so(mca_btl_tcp_add_procs+0x149) [0x404502f9] [4] func:/usr/local/lib/openmpi/mca_bml_r2.so(mca_bml_r2_add_procs+0x155) [0x40440e95] [5] func:/usr/local/lib/openmpi/mca_pml_ob1.so(mca_pml_ob1_add_procs+0xa2) [0x40429492] [6] func:/usr/local/lib/libmpi.so.0(ompi_mpi_init+0x3c7) [0x40088127] [7] func:/usr/local/lib/libmpi.so.0(MPI_Init+0xf1) [0x4007cac1] [8] func:ping_pong(main+0x22) [0x804e0e6] [9] func:/lib/tls/libc.so.6(__libc_start_main+0xf4) [0x4024d974] [10] func:ping_pong(__gxx_personality_v0+0x3a1) [0x804e021] ------- TESTS 3 openmpi-1.0.2a9 ------- into /usr/local/etc/openmpi-mca-params.conf btl_tcp_if_include = eth1 mpirun -np 2 --hostfile mpihosts_cluster ping_pong does NOTHING, it is stalled ------- TESTS 4 openmpi-1.0.2a9 ------- mpirun -np 2 --hostfile mpihosts_out ping_pong btl_tcp_if_include = eth0 OK -------- TESTS 5 openmpi-1.0.1------- 1.- cd openmpi-1.0.2a9 2.- make clean 3.- cd openmpi-1.0.1 4.- ./configure 5.- make all install no parameters into /usr/local/etc/openmpi-mca-params.conf mpirun -np 2 --hostfile mpihosts_out ping_pong IT BLOCKS -------- TESTS 6 openmpi-1.0.1------- mpirun -np 2 --hostfile mpihosts_out ping_pong into /usr/local/etc/openmpi-mca-params.conf btl_tcp_if_include = eth0 OK -------- TESTS 7 openmpi-1.0.1------- mpirun -np 2 --hostfile mpihosts_cluster ping_pong into /usr/local/etc/openmpi-mca-params.conf btl_tcp_if_include = eth1 OK ----------------------------------- So in my opinion it still doesn't work without having to set parameters in the config file. I hope this helps. You all are doing a great job!
