Sierra – cel mai nou supercomputer \u0219i cel de-al treilea cel mai rapid din lume – ruleaz\u0103 Red Hat Enterprise Linux (RHEL), ceea ce nu este surprinz\u0103tor av\u00e2nd \u00een vedere rolul jucat de Linux \u00een ceea ce prive\u0219te supercomputerele \u00een general.<\/p>\n

Pe 26 octombrie, Administra\u021bia Na\u021bional\u0103 de Securitate Nuclear\u0103 (NNSA) – parte a Departamentului Energiei – a dezv\u0103luit cel mai recent supercomputer. Acesta se nume\u0219te Sierra \u0219i este de acum cel de-al treilea super-supercomputer din lume.<\/p>\n

Sierra ruleaz\u0103 la viteza de 125 de petaflopi (performan\u021b\u0103 de v\u00e2rf) \u0219i va fi folosit \u00een primul r\u00e2nd de NNSA pentru modelare \u0219i simul\u0103ri, ca parte a misiunii sale principale de a asigura siguran\u021ba, securitatea \u0219i eficacitatea stocului nuclear al SUA. Acesta va fi utilizat de trei laboratoare separate de securitate nuclear\u0103 – Lawrence Livermore National Labs, Sandia National Laboratories \u0219i Laboratorul National Los Alamos, \u0219i nu ruleaz\u0103 altceva dec\u00e2t Red Hat Enterprise Linux (RHEL).<\/p>\n

Sierra este, de asemenea, primul sistem heterogen la scar\u0103 larg\u0103 a NNSA, referindu-se la faptul c\u0103 sistemul utilizeaz\u0103 at\u00e2t CPU-uri, c\u00e2t \u0219i GPU-uri pentru a-\u0219i \u00eendeplini sarcinile de procesare.<\/p>\n

Sierra este al treilea supercomputer de top, conform ultimei liste TOP500, \u0219i este a\u0219teptat s\u0103 fie de \u0219ase p\u00e2n\u0103 la de 10 ori mai capabil dec\u00e2t Sequoia care ruleaz\u0103 la vitez\u0103 de 20 petaflops.<\/p>\n

Fiecare nod din sistem include at\u00e2t procesoare IBM, c\u00e2t \u0219i unit\u0103\u021bi de procesare grafic\u0103 Nvidia (GPU). Proiectat pentru modelare \u0219i simul\u0103ri, este de a\u0219teptat s\u0103 \u00eenceap\u0103 utilizarea sa ca sistem de produc\u021bie la \u00eenceputul anului 2019.<\/p>\n

Potrivit lui John Kelly, vicepre\u0219edinte senior, Cognitive Solutions \u0219i IBM Research, „Parteneriatul IBM cu LLNL de zeci de ani ne-a permis s\u0103 construim Sierra de la zero cu un design unic \u0219i o arhitectur\u0103 necesar\u0103 pentru aplicarea AI la seturi masive de date. Cercet\u0103torii sunt de p\u0103rere c\u0103 vor accelera doar computerele de \u00eenalt\u0103 performan\u021b\u0103 pentru cercetare \u0219i afaceri. ”<\/p>\n

De ce Linux?<\/strong><\/p>\n

\u00cen timp ce entuzia\u0219tii din Linux ar putea considera c\u0103 este \u00eencurajator faptul c\u0103 Sierra ruleaz\u0103 RHEL, ei ar putea fi mai entuziasma\u021bi s\u0103 afle c\u0103 Linux ruleaz\u0103 acum pe toate supercomputerele incluse \u00een lista TOP500 men\u021bionat\u0103 mai sus. Dac\u0103 g\u0103si\u021bi acest lucru surprinz\u0103tor, lua\u021bi \u00een considerare num\u0103rul de procesoare utilizate, faptul c\u0103 Linux este (\u00een cea mai mare parte) open source \u0219i flexibilitatea extraordinar\u0103 \u00eempreun\u0103 cu securitatea derivat\u0103 din accesare \u0219i, dac\u0103 este necesar, modificarea codului surs\u0103. \u00cen acest context, alte sisteme de operare nu pot \u00eencepe s\u0103 concureze.<\/p>\n

C\u00e2t de mare este mare?<\/strong><\/p>\n

Sierra ocup\u0103 un spa\u021biu de 7000 de metri p\u0103tra\u021bi, cu cele 240 de suporturi de calcul \u0219i 4.320 noduri. Fiecare dintre aceste noduri const\u0103 \u00een dou\u0103 procesoare IBM Power 9 \u0219i patru GPU-uri Nvidia V100 cu interconexiune Mellanox EDR InfiniBand.<\/p>\n

Ce urmeaz\u0103 \u00een materie de supercomputere?<\/strong><\/p>\n

Urm\u0103torul obiectiv este construirea calculatoarelor \u00een clasa „exascale”, potrivit secretarului Departamentului pentru Energie, Rick Perry.<\/p>\n

„\u00cen doar c\u00e2\u021biva ani, ne a\u0219tept\u0103m s\u0103 vedem sistemele exascale lansate la Lawrence Livermore, Argonne \u0219i Oak Ridge (laboratoare na\u021bionale), asigur\u00e2nd superioritatea noastr\u0103 global\u0103 \u00een aceast\u0103 aren\u0103 de zeci de ani”, a declarat Perry. „\u00cencep\u00e2nd cu Sierra, aceast\u0103 nou\u0103 genera\u021bie de supercomputere va fi un nou \u00eenceput \u00een materie de putere de calcul la nivel mondial”.<\/p>\n

Exascale se refer\u0103 la sistemele de calcul care sunt capabile s\u0103 efectueze sau chiar s\u0103 dep\u0103\u0219easc\u0103 un exaFLOP – un miliard de miliarde de calcule pe secund\u0103 – \u0219i ar reprezenta o cre\u0219tere de o mie de ori fa\u021b\u0103 de sistemele petascale care au intrat \u00een func\u021biune acum 10 ani.<\/p>\n

<\/em><\/p>\n

gigaFLOPS\tGFLOPS\t109<\/sup><\/p>\n

teraFLOPS\tTFLOPS\t1012<\/sup><\/p>\n

petaFLOPS\tPFLOPS\t1015<\/sup><\/p>\n

exaFLOPS\t EFLOPS\t1018<\/sup><\/p>\n

<\/em><\/em><\/p>\n

Re\u021bine\u021bi c\u0103 fiecare cre\u0219tere a unit\u0103\u021bilor reprezint\u0103 cre\u0219tere de o mie de ori dec\u00e2t cea precedent\u0103.<\/p>\n

NNSA sper\u0103 s\u0103 treac\u0103 la exascale cu un sistem numit El Capitan \u00een 2023. \u00cen ceea ce prive\u0219te FLOP-urile, sistemul ar trebui s\u0103 fie de aproximativ 10 ori mai puternic dec\u00e2t Sierra. Se a\u0219teapt\u0103, de asemenea, s\u0103 apar\u0103 un alt sistem heterogen care vizeaz\u0103 \u00eenv\u0103\u021barea ma\u0219inilor \u0219i inteligen\u021ba artificial\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
