New page

This page contains information on installing clustering software such as the Sun Grid Engine and parallel programming middleware such as PVM and MPI.

== Sun Grid Engine ==
The Sun Grid Engine can be installed from the backup or from scratch. Below are the instructions on installing it from a backup:

Copy the backed up tar.bz2 on majorana and untar it into /usr/local/sge. Add the following line to /etc/profile:
<pre>
. /usr/local/sge/default/common/settings.sh
</pre>

and in /etc/csh.cshrc:
<pre>
source /usr/local/sge/default/common/settings.csh
</pre>

(All modifications done both on the master and on the clients -- TODO: HALVA WHAT DO YOU MEAN BY THIS?)

Added to /etc/services:
<pre>
sge_commd 536/tcp # Sun Grid Engine
</pre>

	</pre>		</pre>
		+
		+
		+	Export the Sun Grid Engine directory. Modify
		+	<pre>
		+	/etc/diskless-image/config.sh
		+	</pre>
		+	in order to add the correct entry in /etc/fstab on each client node. Search for the block that starts with "cat > /etc/fstab << EOF" and add two (TODO: I only see one!) lines below:
		+	<pre>
		+	192.168.100.101:/usr/local/sge /usr/local/sge/ nfs rw,defaults, 0 1
		+	</pre>
		+
		+	Add the line to:
		+	<pre>
		+	/usr/lib/diskless-image/template/etc/fstab
		+	</pre>
		+	as well.
		+
		+	Rerun dpkg-reconfigure diskless-image-simple, then create the directory:
		+	<pre>
		+	/usr/local/sge
		+	</pre>
		+	in the diskless image.
		+
		+	Then run
		+	<pre>
		+	update-host-directories.
		+	</pre>
		+
		+	Now on majorana:
		+	<pre>
		+	cd /etc; ln -s . rc.d; cd /usr/local/sge/;
		+	./install_qmaster
		+	</pre>
		+
		+	On the diskless image: copy rcsge to /etc/init.d/ and then run:
		+	<pre>
		+	update-rc.d rcsge defaults 95
		+	update-host-directories
		+	</pre>
		+
		+	On polyphemus: add an entry to /etc/fstab to mount r01:/usr/local/sge and
		+	<pre>
		+	cp /usr/local/sge/default/common/rcsge /etc/init.d; update-rc.d rcsge defaults 95
		+	</pre>
		+
		+	'''Note:''' SGE is on majorana, but the schedules is still on polyphemus!
