SCore System Installation on Compute Hosts

1. 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.score.rwcp.or.jp
   comp0.score.rwcp.or.jp
   comp1.score.rwcp.or.jp
   comp2.score.rwcp.or.jp
   comp3.score.rwcp.or.jp
   

2. Edit /root/.bashrc on all hosts so that the following line is added:

   export PWD
   

3. Binary Installation from binary RPMs
   Execute the following commands:

   	# cd /opt/score/work
   	# ./bininstall -compute
   

   You will now find two directories under the /opt/score directory.

4. Device files
   1. Myrinet
      Device files for PM/Myrinet were already created when the binaries were installed using the binary RPMs. You do not need to take care of them.

   2. Ethernet
      The PM/Ethernet init program was already installed in /etc/rc.d/init.d when the binaries were installed using the binary RPMs.
      Edit the /etc/rc.d/init.d/pm_ethernet file and modify the IF variable if the machine has more than one ethernet card and you want to use a device other than the /dev/eth0 device. For example, if you want to use /dev/eth1, the IF variable should be:

      	IF=eth1
      

      Then invoke the following command:

      For Red Hat Linux:

      	# /etc/rc.d/init.d/pm_ethernet start
      

      For SuSE Linux:

      	# /etc/init.d/pm_ethernet start
      

   3. Shmem
      Device files for PM/Shmem were already created when the binaries were installed using the binary RPMs. You do not need to take care of them.

5. Create /etc/score.conf file
   The /etc/score.conf file must be on all hosts for scoutd. Usualy, it copy from server.

   	# rcp server:/etc/score.conf /etc
   

   Then invoke the following command:

   For Red Hat Linux:

   	# /sbin/chkconfig --add scoutd
   	# /etc/rc.d/init.d/scoutd start
   

   For SuSE Linux:

   	# ed /etc/rc.config
   	/START_SCOUTD/s/no/yes/
   	w
   	q
   	# /etc/init.d/scoutd start
   

6. Create the /var/scored directories on all hosts
   The /var/scored directories must be created on all hosts. It is created by binary RPM. If you want to use a /scored file system instead of /var file system, then execute:

   	# rmdir /var/scored
   	# chmod 755 /scored
   	# ln -s /scored /var/scored
   

7. PBS/SCore
   See PBS/SCore Administrator's Guide if you want to use PBS/SCore.
