Hello all,
This may be a silly question but I hope that someone does know the answer. We use Open MPI to run the Intel Benchmarks to test InfiniBand and RoCE network fabrics. We recently installed OFED-4.17 and when we attempt to run the tests, we see the error below. Command: /usr/local/bin/mpirun --allow-run-as-root --mca btl openib,self,vader --mca pml ob1 -np 8 -hostfile /root/mpi-hosts /usr/local/bin/IMB-MPI1 Result: libibverbs: Warning: couldn't load driver 'libsmartio-rdmav17.so': libsmartio-rdmav17.so: cannot open shared object file: No such file or directory libibverbs: Warning: couldn't load driver 'libsmartio-rdmav17.so': libsmartio-rdmav17.so: cannot open shared object file: No such file or directory libibverbs: Warning: couldn't load driver 'libsmartio-rdmav17.so': libsmartio-rdmav17.so: cannot open shared object file: No such file or directory libibverbs: Warning: couldn't load driver 'libsmartio-rdmav17.so': libsmartio-rdmav17.so: cannot open shared object file: No such file or directory libibverbs: Warning: couldn't load driver 'libsmartio-rdmav17.so': libsmartio-rdmav17.so: cannot open shared object file: No such file or directory [sm-node-02][[44319,1],6][btl_openib_component.c:1670:init_one_device] error obtaining device attributes for mlx5_0 errno says Success [sm-node-02][[44319,1],5][btl_openib_component.c:1670:init_one_device] error obtaining device attributes for mlx5_0 errno says Success [sm-node-02][[44319,1],4][btl_openib_component.c:1670:init_one_device] error obtaining device attributes for mlx5_0 errno says Success The folks who build OFED believe libsmartio-rdmav17.so is not part of the OFED package. It is not in RDMA-Core. I have searched for information on this object and can't seem to find anything. If anyone knows anything about it or (especially) thinks that we should change our mpirun command options, or has pointers to where I should direct this question, I would appreciate the help. OS: CentOS 7.4; (kernel: 4.17.14-1.el7.elrepo.x86_64) OFED: OFED-4.17-20180822-1352 (https://www.openfabrics.org/downloads/OFED/ofed-4.17-daily/OFED-4.17-201808 22-1352.tgz) I will be happy to provide any additional information if needed. Thanks. -- Llolsten
