Any advice or comments? Thanks in advance!
Will anyone give some advice? Thanks in advance. Here are the different file locations on my SLES and RHEL nodes. Looks like rdma_ucm module didn't get loaded. Check /etc/infiniband/openib.conf and make sure loading rdma_ucm is set properly: [EMAIL PROTECTED] dapl]# cat /etc/infiniband/openib.conf # Start HCA driver upon boot ONBOOT=yes # Load RDMA_CM module RDMA_CM_LOAD=yes # Load RDMA_UCM module RDMA_UCM_LOAD=yes -arlin
