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:

. /usr/local/sge/default/common/settings.sh

and in /etc/csh.cshrc:

source /usr/local/sge/default/common/settings.csh

(All modifications done both on the master and on the clients -- TODO: HALVA WHAT DO YOU MEAN BY THIS, WHICH MODIFICATIONS DO "ALL" REFER TO IN "ALL MODIFICATIONS" --- I know it should be easy, but I am still slightly confused?)

Added to /etc/services:

sge_commd	536/tcp	# Sun Grid Engine


Export the Sun Grid Engine directory. Modify

/etc/diskless-image/config.sh 

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:

192.168.100.101:/usr/local/sge   /usr/local/sge/	nfs rw,defaults,	0	1

Add the line to:

/usr/lib/diskless-image/template/etc/fstab

as well.

Rerun dpkg-reconfigure diskless-image-simple, then create the directory:

/usr/local/sge

in the diskless image.

Then run

update-host-directories.

Now on majorana:

 
cd /etc; ln -s . rc.d; cd /usr/local/sge/;
./install_qmaster

On the diskless image: copy rcsge to /etc/init.d/ and then run:

update-rc.d rcsge defaults 95
update-host-directories

On polyphemus: add an entry to /etc/fstab to mount r01:/usr/local/sge and

cp /usr/local/sge/default/common/rcsge /etc/init.d; update-rc.d rcsge defaults 95

Note: SGE is on majorana, but the schedules is still on polyphemus!
