Error “ssh: Name or service not known” while using mpirun in Linux

I have successfully compile MPICH library in my linux cluster and also export the variable in ~/.bashrc. 

# MPICH
export PATH="$/disk2/usr/lib/mpich/bin:$PATH"

But while I use mpirun for multi-core computation. The error would appear like this:

ssh: Xiehost: Name or service not known

Xiehost is my linux cluster's name. And I use ssh to control it.

The .exe was successfully execute with one core. And mpirun is essential for my project with better efficiency.

Any advice would be appreciate.
