Re: [MISC] Eksempler på brug af Linux?



Jan Hertel wrote:
I vores folder "Linux & fri software" skriver vi:

"I dag bruges frit software mange steder, både i lille og stor skala.
Den tyske by, Münchens administration er i gang med at overgå til kun
at anvende fri software. Det samme gælder f.eks. Deutsche Bahn, de
nationale tyske jernbaner."

Hvordan går det mon med de to steders brug af Linux/open source? Er
der andre og bedre eksempler?



Danmarks Meteorologiske Institut (DMI) har længe brugt Linux, og har i December 2007 bestilt en ny supercomputer baseret på Linux.

DMI køber monster-computer med 3.500 CPU'er
Citat:
DMI underskrev mandag kontrakten på den nye monster-computer, der rummer cirka 3.500 AMD-cpu’er, knyttet sammen i en slags Linux-klynge. Den dynamiske arbejdshukommelse bliver på syv Terabytes. Cpu’erne er forbundet med hinanden gennem et specialudviklet, hurtigt lokalnetværk ved navn Seastar. Diskpladsen bliver på godt 100 Terabytes, og det skal give plads til cirka 14 dages data til de danske 1-2 døgns prognoser. Det er de mest præcise vejrudsigter. Kombinationen af netværksforbindelsen og de hurtige Linux-kerner er med til at give en betydeligt bedre skalerbarhed end andre systemer, vi har prøvet. Vi har lavet en hel del benchmarking først,« siger Leif Laursen, meteorolog og nyudnævnt forskningschef hos DMI.
Citat slut.

Computeren er en Cray XT5 Supercomputer:
http://www.cray.com/products/xt5/xt5.html
Building on the successful Cray XT™ product line, the Cray XT5™ system is the single most scalable Linux supercomputer. The Cray XT5 system combines unprecedented sustained application performance with exceptional manageability and reliability, lower cost of ownership and, with a Linux environment, broader application support to large supercomputer class machines.
