Adding Slurm

1. First configure the LDAP datastore. See Adding OpenLDAP.

2. Install slurm command line.

3. Add to /etc/sudoers:

   www-data ALL=(slurm) NOPASSWD: /usr/local/slurm/latest/bin/sacctmgr
   

4. Test using www-data user:

   sudo -uslurm /usr/local/slurm/latest/bin/sacctmgr -ip
   

5. Add project to slurm that has no access. Call it default (or whatever else you want).

6. Edit the DATASTORES setting in /etc/karaage3/settings.py:

   DATASTORES = [
       {
           'DESCRIPTION': 'LDAP datastore',
           ...
       },
       {
           'DESCRIPTION': 'Slurm datastore',
           'ENGINE': 'karaage.datastores.slurm.SlurmDataStore',
           'PREFIX': [ "sudo", "-uslurm" ],
           'PATH': "/usr/local/slurm/latest/bin/sacctmgr",
           'NULL_PROJECT': 'default',
       },
   ]
   

   Values PREFIX, PATH, and NULL_PROJECT are defaults and can be omitted.

7. In /etc/karaage3/settings.py uncomment the LOGGING assignment lines related to slurm.

8. Reload apache.

   service apache2 reload
