SCore System Installation on Compute Hosts from Source

Set up networking
/root/.rhosts and the /etc/hosts.equiv files must contain all server and compute host names so that the rsh command works on all hosts. For example,
```
server.pccluster.org
comp0.pccluster.org
comp1.pccluster.org
comp2.pccluster.org
comp3.pccluster.org
```
To rsh by root, please execute as following:
```
# echo rsh > /etc/securetty
```
Then enable rsh rlogin to the compute host.
```
# /sbin/chkconfig rsh on
```

Binary Installation from Server

Mount the /opt/score directory of the server on the compute host, or then execute the following commands:

    # rdist -c /opt/score/*/deploy computer-host:
    # rdist -c /opt/score/*/lib/build computer-host:
    # rdist -c /opt/score/*/crt.* computer-host:
    # rdist -c /opt/score/*/install computer-host:

And then the following commands:

    # cd /opt/score/install
    # ./setup -score_comp

Edit /root/.bashrc on all hosts so that the following line is added:
```
export PWD
```
PM/Ethernet init program
The PM/Ethernet init program was already installed in /etc/rc.d/init.d.
To use PM/Ethernet, please create /etc/pm_ethernet.conf file. For example, if you want to use eth0 at unit 0, please following lines in the /etc/pm_ethernet.conf. variable should be:
```
    PM_ETHERNET_UNIT_ETH0=0
```

Then, please reboot the compute hosts

# /sbin/reboot
