Intel mpi cannot ssh to node (RHEL 7.7)
by ViktorNazd from LinuxQuestions.org on (#5R9RW)
Dear, all
I have a problem to make cluster computing on two nodes. I can did it easily on ubuntu. But the consumers need it on RHEL 7.7 and there I have some dificulties. With Intel mpi I get endless trying to use second node. I've tried mpich and it shows "Host key verification failed", but I'm sure it's set correctly: connection without password due to SSH can be reached, I checked known_hosts and key files and they are correct.
Does anybody knows what's the problem?
Kind regards,
Viktor
