1. Install Linux box grid-X,

 * Ensure the following are there: perl, python, g++ for c/c++/fortran, Tcl.
 * mount nfs service from grid-0 to  /nfs/disk
 * define the node name as grid-X and update /etc/hosts for the nodes to reflect the new node.
 * copy /etc/bash.bashrc from grid-0 to the new node

2. Install NIS service, propagate the NIS account from grid-0

3. Install SGE, accepted by grid-0

4. Install additional tools

some tips:

1. statistic IPs are used right now. For that configure /etc/conf.d/netcfg. Check /etc/network.d/examples to create a profile. systemctl enable netcfg is needed to enable the service. DHCP should be disabled, i.e., systemctl disable dhcp@eth0.

2. in the old nodes, grid-0 and gird-1, the netcfg is enabled by replacing network by net-profiles in DAEMON of /etc/rc.conf.
