Is China a supercomputer threat? (Q&A)
http://news.cnet.com/8301-13924_3-20021122-64.html
With China expected to officially take the supercomputer performance crown
next month, I asked an expert about the state of supercomputing in the U.S.
and whether China poses a long-term threat to the United States' current
preeminence in supercomputing.
Nvidia announced yesterday that its chips are powering the "Tianhe-1A"
Chinese supercomputer that achieved 2.507 petaflops, beating a U.S.-based
system that is currently ranked No. 1 on the June Top500 list of the fastest
supercomputers in the world. The Chinese system is a unique hybrid design
that uses approximately 7,000 Nvidia graphics chips along with 14,000 Intel
Xeon CPUs. The graphics chips are what give the system the extra oomph to
catapult it into the top supercomputer spot.
I spoke with Jack Dongarra, university distinguished professor at University
of Tennessee's Department of Electrical Engineering and Computer Science
and part of a group from the University of Tennessee, Oak Ridge National
Laboratories, and Georgia Tech that recently purchased a hybrid system. It
is important to note that Oak Ridge houses the supercomputer, dubbed "Jaguar
," cited above that is currently ranked No. 1 in the world based on the
Top500 June list: it is not a hybrid system.
Q: Does Oak Ridge have anything analogous to the Chinese hybrid system?
Dongarra: Oak Ridge has a small version of a machine that is hybrid in
nature. So, this is an acquisition that just took place...out of a grant
from the National Science Foundation. It involved Oak Ridge National Labs,
University of Tennessee, and Georgia Tech. But it's much, much smaller than
the Chinese system. The machine is in place and testing is being carried out
at Oak Ridge. A node has two Intel Westmere chips and three Nvidia Fermi
boards. There are 120 nodes in the system.
What makes the Chinese supercomputer so fast?
Dongarra: The Chinese designed their own interconnect. It's not commodity.
It's based on chips, based on a router, based on a switch that they produce.
Is that in essence the secret sauce?
Dongarra: It's similar to Cray. Cray's contribution, besides the integration
and software, is the interconnect network. They have a very fast
interconnect that makes that machine perform very well. Though [the Chinese]
project is based on U.S. processors, it uses a Chinese interconnect. That's
the interesting part. They've put something together that is roughly twice
the bandwidth of an InfiniBand interconnect [which is used widely in the U.S
.]
Will the Chinese system in fact take the No. 1 spot on the Top500 list in
November?
Dongarra: Yes. I saw the machine. I saw the output. It's the real thing.
Why doesn't Oak Ridge do what the Chinese are doing?
Dongarra: Oak Ridge doesn't have the ability or technology to develop an
interconnect or a router. We don't make computers. We buy computers and use
them. It's not within our scope or mission to be in the computer design
business.
What's your advice?
Dongarra: You have to remember that you have to not only invest in the
hardware. It's like a race car. In order to run the race car, you need a
driver. You need to effectively use the machine. And we need to invest in
various levels within the supercomputer ecology. The ecology is made up of
the hardware, the operating system, the compiler, the applications, the
numerical libraries, and so on. And you have to maintain an investment
across that whole software stack in order to effectively use the hardware.
And that's an aspect that sometimes we forget about. It's underfunded. We
fund the hardware but we don't the other components. The ecosystem tends to
get out of balance because the hardware tends to run far ahead of what we
can develop in terms of software. We have machines that have a tremendous
level of parallelism. We currently have a very crude way of doing
programming.
Who would do that?
Dongarra: The research is performed under the auspices of the Department of
Energy, the National Science Foundation, and the Department of Defense.
Is this a red flag for the U.S.?
Dongarra: Yes, this is a wake-up call. We need to realize that other
countries are capable of doing this. We're losing an advantage.

没有。
It will have a peak performance of 10 petaflops (10 quadrillion calculations
every second) and will achieve sustained performance of 1 petaflop running
a range of science and engineering codes.
看清楚了,是peak performance 10 petaflops, sustained performance of 1
petaflop. 也不咋地呀,还明年才出来。
而且我说的是橡树岭没赶上潮流。bluewater是橡树岭吗,杠头?

theoretical peak computing capability of 16 petaflops. This will supposedly

achievable by connecting up to 16,384 Power7 nodes, but IBM doesn't expect
the
