Using GEMS at Notre Dame

System Status

There are currently two GEMS installations at Notre Dame, a dedicated server for use by applications and scientific users, and a development server for use by the GEMS team during research and development of the system.

Getting Started with GEMS

Notre Dame Settings

The following .gemsclient file should be copied to your home directory.

<GEMS>
  <GEMSclient>

  <chirp>
   <user>unix</user> 
   <user>hostname</user> 
  </chirp>

  <servers>
   <host>gems.cse.nd.edu</host>
  </servers>

   <acl> 
    <entry principal="hostname:*.helios.nd.edu" 
        perms="lr" /> 
   </acl> 

   <storage name="nd">
    <cluster name="helios">
     <pattern>*.helios.nd.edu</pattern>
    </cluster>
   </storage>

 </GEMSclient> 
</GEMS>

  
  • Unix or hostname authentication are common choices.
  • Use the dedicated server, gems.cse.nd.edu.
  • This ACL allows anyone to read your data from a helios machine. Remove this section to keep your data private.
  • This storage map sets you up to use only helios machines. If you have access to other machines, you may add them as additional clusters.
