How to install Atlas software for a cluster

WARNING: This page is obsolete.

This assumes that there is a local cluster of computers which have been setup and each node has GLite installed with the yum method and available to all users. There is no reason why this procedure cannot be used for a single-user machine.

This is still a work in progress ... there are probably better ways to do this and we will ammend this page as needed.

Create the installation directory and links

Select the area where you want the software installed (/data/isabel1/AtlasLocalInstallation in the example below) and do the following:

        mkdir /data/isabel1/AtlasLocalInstallation
        mkdir /data/isabel1/AtlasLocalInstallation/i686
        mkdir /data/isabel1/AtlasLocalInstallation/x86_64

and then, for each node of the cluster, soft link them from the root directory

ln -s /data/isabel1/AtlasLocalInstallation/i686 /ATLAS_LOCAL_ROOT
        or
ln -s /data/isabel1/AtlasLocalInstallation/x86_64 /ATLAS_LOCAL_ROOT)

There are reports that installing both architectures on the same tree may cause problems, hence the separate 32/64 bit directories.

From now on, navigate to the area with /ATLAS_LOCAL_ROOT. Also, note that ATLAS_LOCAL will be prepended to all variable names in the installation procedure below.

Install Pacman

you can install it or do the following:

Install a Multi-kit

Do the following to install a kit - this will only install the Athena release for a specific architecture.

cd /ATLAS_LOCAL_ROOT pacman -get http://trshare.triumf.ca/~atlas/ATLAS.mirror:Multi -allow tar-overwrite

(+KV will fail because of the following error: removing Multi+KV as some of the old kit validations no longer work)
