10 month 30 news, a new type of global "arms race" is the curtain,hp pavilion dv7t 4000-cto laptop cpu fan but this time the competition is one quadrillion times (petaflop) as the calculating unit.
The department of energy's super computer "titans" (Titan) Monday
officially online, the ministry of this computer was developed, are
likely to make its become the planet's fastest supercomputer. "The
Titan" have 20 quadrillion times per second calculation ability, than
the department of energy's another supercomputer "Sequoia" (Sequoia)
more than 4 quadrillion times, the latter has been since June this year
in global super computer list occupies the first place. Formal the
world's fastest supercomputers "fortune 500" list will be released next
In the past three years, the United States in the calculation of the
world of the "territory" has been in Japan, China and Germany carve up,
but now the United States is to get back a leading position. This is not
just a kind of "medal of honor", and at the same time, for national
security and economic viability of the United States is also very
important.hp pavilion dv7t 3300-cto laptop cpu fan
The Titan will help scientists in the United States in the climate
change, biofuels, nuclear energy, new materials and other key areas
occupy the research pioneer status, this will help them to create a new
wave of car battery, switchgrass ethanol and the improved weather
forecast tools and other products.
In the United States department of energy affiliate Oak Ridge National
Laboratory (Oak Ridge National Laboratory), by the global leading
enterprise in the super computer Cray company produces "Titan" has made a
major upgrade, a super computer formerly known as "the Jaguar"
Compared with "the jaguar", "the Titan" with AMD hp pavilion dv7t 3100-cto laptop cpu fan
the production of 299008 a faster the central processing unit (CPU) to
replace the former 224256 CPU, also equipped with the production of
18688 by the Nvidia graphics processor as the central processor
accelerator, this is why "Titan" equipped with central processor number
only a third more than "jaguar", and computational nodes and cabinet
quantity and "jaguar" the same, but the computing power is equivalent to
the former ten times the reason.
More important is, "Titan" processor than the United States department
of energy after the use of super computer energy conservation to five
To maximize the operation speed of the competition, "Power bound" (Power
constraint) is one of the biggest challenges. "The jaguar" computing
power is only 2.3 quadrillion times per second, but its power
consumption is as high as 7 mw, equivalent to 7000 families of the
electricity consumption. Last year, "the jaguar" single power
consumption is a cost to reach 7 million dollars. If the "Titan" and
"the jaguar" is only increased compared to the number of the central
processor, but not equipped with graphics processors, then this table
every seconds computing capacity of 20 quadrillion time of super
computer hp pavilion dv7t 3000-cto laptop cpu fan
power consumption will reach 60 mw, every year sheet is electricity use
the cost would be up to us $60 million, and the original will mean Cray
cannot with the United States energy department to complete the
production the supercomputer agreement.
Oak ridge national laboratory says, "the Titan" electric power cost only
slightly higher than the jaguar "some. The laboratory for calculation
and computer science laboratory deputy director Jeff Nichols (Jeff
Nichols) says, "the Titan" design is "toward lower we" carbon footprint
"and take the responsible a steps".
"The Titan" use of the graphic processor is not special, actually these
graphics processor and high-end personal computer hardware used in
general no two, a computer game "fever" favorite. This is not the first
time the game help supercomputing made development - in Los Alamos
National Laboratory (Los Alamos National Laboratory), IBM RoadRunner hp pavilion dv7t 2200-cto laptop cpu fan super computer operation of the processor and with the SONY PlayStation 3 use processor is the same.
"The development of high performance computing processor will cost
billions of dollars of money, and can't recover." Nvidia chief technical
officer Steve Scott (Steve Scott) said. "If there is no individual
consumer business as a support, so we are unable to do now is doing."
So, in developed has new operation speed and power "Titan" later, the
United States energy department plans to use the new super computer do
what? Oak ridge national laboratory plan is, to continue to focus on the
new super computer currently used in the 40 projects, but each project
received CPU time no longer to do for the unit of measurement, but with
hundred million for the unit, this will help the researchers to speed up
its process of a breakthrough. However, the researchers want to get
faster speed it is just a matter of time. By 2016, the U.S. department
of energy will upgrade Titan, hoping to its inheritor operation speed
increased to 200 quadrillion hp pavilion dv7t 2000-cto laptop cpu fan times per second, namely is equivalent to the "Titan" ten times.
"Demand is eternity. Scott said. "Once we are ten billion times
(exaflop) edge, then scientists will begin to discuss their to ten
trillion times (zettaflop) needs."
