Operating Systems[edit | edit source]

Linux[edit | edit source]

GNU/Linux aims to be a free and open-source unix (or unix-like) operating system that will run on most types of computer hardware and uses an X11 graphical user interface. Various distributions of GNU/Linux exist that have different package management systems and other features. Most of these are ideal platforms for X-ray crystallography and other scientific computational requirements.

Linux Distributions[edit | edit source]

  • OpenSuse will run most Red Hat and Fedora packages

These differ greatly in the time they support their releases:

Mac OS X[edit | edit source]

Mac OS X is a proprietary BSD-Unix-derived operating system that runs on Apple's computers. The BSD-subsystem, called Darwin, attempts to be open-source. Unlike most other flavors of Unix, OS X is not based on an X11 windowing system, but instead uses a proprietary Aqua graphical user interface. For crystallographers and others who need the conventional X11 windowing system, an Xserver for OS X is available, and can be easily installed on all versions of OS X.

Irix (SGI)[edit | edit source]

By all accounts, SGIs are now obsolete. They are more expensive and perhaps offer higher productivity, but it is not worth the money when $500 Linux box takes 1/2 hour to calculate a simulated annealing omit map. There are some examples of software (such as GRASP) that you can only run on SGIs, not Linux. O is also wicked fast on SGIs.

Irix is a flavor of UNIX and is still supported by SGI.
