aragon is now a general access Tru64 UNIX system

As of Monday, November 12th, the Compaq Alpha XP1000 system called aragon in the Huxley 613 open access room is no longer a member of the Maths Physics cluster. Instead it is now available for use by anyone in the Maths department and the default home directory at login will be the general Maths one hosted on the geometry2 server. This follows on from the move of the Linux system cathedral last Monday (see earlier item, below) and Maths Physics users should note that access to Maths Physics cluster home directories is still possible as described below.

Linux Matlab upgraded to R2007a

The networked version of Matlab served by the Linux applications servers (elvis1 and elvis2) was upgraded to Matlab R2007a (also known as Matlab 7.4) on November 8th. This is now the default version started by simply typing 'matlab' at a shell prompt - earlier versions are still available and can be started with the following commands:

matlab65 - starts Matlab 6.5 (release 13)

matlab71 - starts Matlab 7.1 (release 14)

Note that there is no proper support for X-windows in the 64-bit Linux version of Matlab 6.5 so this version will start up in command line (CLI) mode only on 64-bit Linux systems. (The 32-bit version of matlab 6.5 however is fully functional in both X-Windows and command line modes).

Users of older Linux distributions note: Matlab R2007a requires a recent version of Linux as it depends on certain newer libraries only available in later Linux versions. If you are using a system with an older Linux installation, please continue to use the previous version of Matlab 7.1, at least until your system is upgraded.

cathedral is now a general access Linux system

From Monday, November 5th, the Linux computer cathedral in the Huxley 613 open access room is no longer a member of the Maths Physics cluster. Instead it is now available for use by anyone in the Maths department and the default home directory at login will be the general Maths one hosted on the geometry2 server.

If you are a Maths Physics user, you can still use this system but you must login using your college username & password (which may be different to your Math Phys account) and once logged in, the default home directory will be the one from geometry2 rather than the Math Phys home directory on the ICT NFS server. You can then change to your Math Phys home directory under /home/icnfs/ma/i where i is the first letter of your username.

Math Phys users who still wish to log into a Maths Phys Linux machine via a remote connection should now use whistler instead - this system has an identical software installation to cathedral although it is not publicly physically accessible.

Closure of Imperial's Usenet news server

Although not widely advertised to members of the College, the ICT news server news.cc.ic.ac.uk was shut down on Friday, June 29th. The reasons for this are not clear but those of you who use Usenet news can use the JANET news server instead and the address of the server is ic.jnrs.ja.net. All you need to do is to update your newsreader configuration, replacing news.cc.ic.ac.uk with ic.jnrs.ja.net.
