Titan: CPU and GPU combine for a supercomputer has 20 petaflops

Technology – the course of the 20 pé taflops approaches. In addition to IBM, CRAY will also deliver him, in the United States, for a coû T d’ approximately 100 million dollars, an able supercomputer d' to offer a performance of point dé passing 20 petaflops.

The United States counts dA©velopper well the capacitA©s calculation of their supercomputers. IBM has dA©jA  annoncA© qua?? with the Sequoia project, it would deliver a machine of 20 pA©taflops to Lawrence Livermore National Laboratory (US).

But this last will not be the only one has  accroA®tre its performances in matiA¨re of calculation. Will the national laboratory amA©ricain D `Oak Ridge thus be equipped da?? a new supercomputer baptisA© Titan. It its?? da will act?? does an extension of its have?? of does manufacturer CRAY have?? , currently 3rd with the classification with 1,75 pA©taflop.

Titan be able D `to offer a performance of point dA©passant 20 petaflops, Ca?? is-HAVe – to say has “twice faster and three times more autonomous than the supercomputer have  this day has”, has  to know of the institute avancA© of computer sciences of Kobe in Japan.

\#?? structure retained for Titan thus consists has  to associate graphics processors, of Nvidia Tesla and CPU. Among the supercomputers in the world, three combine dA©jA  CPU and GPU.

It its?? acts of Chinese Tianhe-1A (2,56 pflop/s), Nebulae (1,27 pflop/s) and of Japanese Tsubame 2. 0 (1,19 pflop/s). ConcrA¨tement, for Titan, they are 18. 000 GPU Tesla of new gA©nA©ration which have? tre installA©s in 2012.

In 2010, France thus brought into service, the supercomputer of the ECA dotA© D `1,05 pA©taflop/s of computing power. The ECA had A©galement levA© the veil has  this occasion on its ambitions in this sector, prA©voyant Tera 1000.

This last should cross the course of the 30 in theory pA©taflops (either an increase da?? a factor 30). Next A©tape will be that of calculation exaflopic has?? that is to say a billion billion da?? opA©rations a second.

Dell put on Windows 8 and the PC

StratA©gie – the firm texane considè Re the marché PC like a é lé lies central of its straté gie for the anné be &worsen; to come. Dell ré in addition affirm its partnership with Microsoft and setting on Windows 8 for é quiper diffé rents final.

With?? occasion of the annual confA©rence Dell World which its?? is
held in Texas, Michael Dell has annoncA© that?? company miserait much on
Windows 8. Has “has We are trA¨s alignA©s with Microsoft on Windows 8. Us
you will say some more on and you will see broad A©ventail of
produitsA has”, it promised.

In addition to the PC, one thus can its?? to wait has  to see
to arrive of the signA©es Dell. The future systA¨me da?? exploitation
of Microsoft is thus appelA© has  to play a central rA/le in the stratA©gie of?? company
for the annA©es which come.

Shelves and mobiles: Dell took tempA©rature of the marchA©….

Evoking the marchA© mobilitA©, Michael Dell
is my? me allA© a little further in while leaving clearly
to hear qua?? Android has “has is certainly also another opportunitA©, but
this marchA© its?? is not dA©veloppA© has  height of Has”.

Steve
Felice, prA©sident it of division general public and TPE/PME at Dell has him
some little enjolivA© things by explaining that the marketing of
mobile terminals (tabletteA, smartphones Android and Windows Phone7) had value
da?? expA©rience to observe of which maniA¨re this marchA© dA©veloppe.

has “has We have lancA© a sA©rie products and they were sold, but us
let us have lancA©s in small volumes to measure the rA©action of the clientsA has”.
But for him, the problA¨mes liA © S.A.  the sA©curitA©?? interopA©rabilitA© and
do management of the terminals still have? tre rA©glA©s before da?? to consider a percA©e
in company.

Assessment, for Dell, the PC still has the beautiful ones and long days in front
he. “Has There has are 1,5 billion, Ca?? is a A©norme figure.
Do the prA©visions suggA¨rent qua?? there will be 2 billion da them?? here some annA©es,
thus Ca?? is a marchA© of croissanceA has” analysis Michael Dell. (Eureka Press)
