ISD Unix Services
ISD offers UNIX services and technical support in addition to its Novell/Windows-based services.
Unix was originally written at AT
Unix comes in many "flavours" including Solaris and Linux. ISD supports only these.
ISD administers two Unix machines, Cosmos and Eric, available to staff and students for research and study.
Cosmos is an 8-processor Sun Microsystems machine available to all for running applications and for programme development. A batch system is available on Cosmos for those users who wish to run long computational jobs (e.g., over 24--48 hours); interactive running of shorter jobs is tolerated.
Cosmos may be accessed from office- and home-based machines, and from the PC clusters, by using telnet (or, better, ssh) and, graphically, by use of the X Windows System (e.g., by using Exceed or XFree86).
Eric is a 28-processor Sun Microsystems machine with 30 Gbytes of RAM. At present Eric is available only to members of research groups involved in a JREI bit which funded its purchase. However, it is expected that from late November Eric will be available to all staff and students, in particular for long-running computational jobs.
Many applications are available on Cosmos and Eric, including: Abaqus, Gaussian, Mathematica, Matlab, Patran; C/C++/Objective C and Fortran compilers (with the NAg numerical analysis libraries and the Uniras graphics libraries); and a great deal of free software too, including Perl and Emacs.
Both Cosmos and Eric run the Solaris 7 operating system.
Several departments run Unix machines and clusters. User should contact departmental representatives for details.
Solaris is the flavour of Unix developed by Sun Microsystems. UMIST has a site license for Solaris.
Linux is an increasingly popular flavour of Unix. It is available for free download and installation from many web sites (including doolittle.csu.umist.ac.uk. It can also be purchased on CD ROM from the many distributors of Linux (including RedHat, Mandrake, SuSE and Debian). Linux is usually installed on standard PCs, but is also available for other architectures. Linux can happily co-exist with Windows on a PC giving users a choice of OS at boot time.
For more information see http://www.umist.ac.uk/isd/linux ISD supports only the RedHat distribution of Linux.
To gain access to Cosmos (and in the future, Eric), ask at the ISD Helpdesk. (Users are not registered for Unix services by default.) An account will usually be ready for use within 24 hours. Further information on Cosmos and Eric (including a full list of available applications), and Unix in general is available at www.umist.ac.uk/isd/unix.
(In the past student accounts on Cosmos were limited to those who met certain study or reseach-related criteria. This is no longer the case --- students are encouraged to investigate the Unix service.)
