Rama upgrade

Rama needs upgrading to a supported operating system. SLES10 looks like a good choice as it will last for the rest of the machine's natural life.

Things that will change:

• The very oldest compilers will be dropped
• The ancient OpenPBS queueing system will be replaced with shiny new Torque (it'll look exactly the same to users, but work lots better behind the scenes)
• environment modules will be made sane and compulsory
• queue names rationalised
• node names rationalised in Torque
• /var will be made a reasonable size
• maybe we'll get bigger disks and so more space
• /users will become /home (but I'll make a symlink)

Things to worry about:

• support for SCSI controller - looks like the dpt_i2o module is standard so unlikely to be a problem. Might be a plan to boot the thing off the SLES10 CD before mucking about with the RAID though, just to be sure.
• Will the system support bigger disks? Streamline are kindly investigating.
• I assume the nodes PXE boot

Things to do:

• get my hands on the management software for the RAID controller.

Although it is starting to look like it is not downloadable for Linux.
