I am trying to link two computers (both centos 7) using PBS for running and scheduling mpi jobs. I am using first computer as head node and also as execution node and client node. I have all the services (pbs_comm, pbs_mom, pbs_sched, pbs_server.bin) working and I can submit jobs to default queue. I have installed pbs_execution on the second machine and verified pbs_mom is running. Using pbs_hostn I verified i can see server. But when I do "pbsnodes -a " i keep getting error:
No route to host
pbsnodes: cannot connect to server manowar, error=113
Can someone tell me how to fix this?
