MareNostrum \u00e9s l’ordinador m\u00e9s potent d’Espanya i el\u00a040 del m\u00f3n segons la llista TOP500<\/a> del novembre del 2008 (L’any 2006 era el 5\u00e8 ordinador m\u00e9s potent del m\u00f3n). Podem afegir dues dades curioses sobre aquest gran ordinador. Anualment consumeix a prop d’un mili\u00f3 d’euros d’electricitat. Si ara es puguesin (Per q\u00fcestions econ\u00f2miques) substituir els processadors dels actuals m\u00f2duls, pel processador que fa servir la PlayStation, augmentaria la seva capacitat de c\u00e0lcul per 100, amb un consum d’electricitat nom\u00e9s 10 vegades m\u00e9s gran.<\/p>\n

MareNostrum utilitza nodes BladeCenter JS20 amb processadors duals IBM PowerPC 970FX de 64 bits a 2.2 GHz i es basa en el sistema operatiu Linux. El superordinador t\u00e9 una capacitat de c\u00e0lcul de 62,63 teraflops amb punts de 94,208 teraflops.<\/p>\n

<\/p>\n

El sistema compta amb 20 terabytes de mem\u00f2ria central i 280 terabytes de disc.Els processadors de l’ordinador tenen una arquitectura de 64 bits. Els nodes es comuniquen entre si a trav\u00e9s d’una xarxa Myrinet de gran ample de banda i baixa lat\u00e8ncia.<\/p>\n

F\u00edsicament es localitza a l’interior d’una antiga capella de la Torre Girona, al campus de la UPC de Barcelona, dins d’un prisma de cristall de 9 x 18 x 5 metres, ocupa una instal\u00b7laci\u00f3 de 160 m\u00b2 i pesa 40.000 kg.<\/p>\n","protected":false},"excerpt":{"rendered":"
