Greetings, Until today I was running my openmpi applications with no errors/warnings Today I restarted my computer (possibly after an automatic openmpi update) and got these warnings when running my program [tohiko@kw12614 1d]$ mpirun -x LD_LIBRARY_PATH -hostfile hosts -np 10 hello librdmacm: couldn't read ABI version. librdmacm: assuming: 4 CMA: unable to get RDMA device list -------------------------------------------------------------------------- [[21652,1],0]: A high-performance Open MPI point-to-point messaging module was unable to find any relevant network interfaces:
Module: OpenFabrics (openib) Host: kw12614 Another transport will be used instead, although this may result in lower performance. -------------------------------------------------------------------------- [kw12614:03195] 10 more processes have sent help message help-mpi-btl-base.txt / btl:no-nics [kw12614:03195] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages Is this normal? And how come it happened now? -- Tohiko
