IRIDIA cluster todo

This page contains a list of items which still need to be done on the cluster.

Errors & problems:

• There is a random error when installing the clients in the rack with FAI. The clients start to output a lot of things on screen, but unfortunately they scroll to fast to be read. I could not find any way to block them.
• Neither yppasswd nor passwd work on the clients of the NIS domain. User have to change password from majorana.
• Max: in order to have LAM/MPI works we need to set on each node update-alternatives --config rsh to the option 2 (ssh)

Improvements:

• A daemon that checks the status of the UPS should be installed on both majorana and polyphemus.
• Make the configuration of the package on the diskless and on the rack more similar. At the moment FAI takes care only of modifing the important configuation files in /etc.
• Use one repository for the configuation of those packaged which use debconf. This program can be used to access configuration DBs also shared via NFS of querying a LDAP server.
• Create a script to automatically install/upgrade packages on the clients
• Set up the backup server to automatically backup configuration files on the cluster.
• Move the SGE scheduler to majorana, and configure polyphemus in order to be only a submission host.
• Add a DNS server that caches queries from the local network, so to reduce load (and possible problems) on the ufficial DNS.
• modify update-cluster scripts on majorana, so to create different dsh groups: athlon*, opteron*, diskless, rack, etc. This can be done coding the information in a special way in the notes of each node.

Wishlist:

• Install Ganglia to monitor the usage of the cluster via web.
• Install LDAP instead of NIS (only if it is better or it works).
• Install a new version of Sun Grid Engine (or something else).
• Install Bugzilla to trace problems on the cluster (and to have a knowledge base of how to solve them!).
