I use openmpi1.2, I try to run the command on remote host such as ,run command on ps3-1: $ mpiexec -host ps3-2 -n 2 ./a.out there appear same error message.I think there is something wrong with rsh/ssh,but I don't where to modify or some file I missed. if someone met same problem,please tell me the solution. I will be grateful. thanks very much!
