Hi Kent

If you are unable to get the video let me know and I can get a digital copy
to you.

Subject: [Year 12 IT Apps] Undersea cable....

This morning on Inside Business(I think it was this program..was about 10am
or so..) on the ABC(sunday morning), I noted a segment about our internet
speed issue and also mention of the undersea cable from Oz to overseas
venues. It also mentioned about the majority of the internet traffic being
about (70% was the stated figure) download of music and videos and P2P
sharing(the word 'illegal' was also used).
Did anyone tape it? Might be good for a discussion in class for those so
inclined...

Kent.

Subject: [Year 12 IT Apps] Top500 supercomputers

Top 500 supercomputers:
Welcome to the petaflop generation
Submitted by Layer 8 on Wed, 06/18/2008 - 10:06am.

Welcome to the petaflop generation. That was the message today as the new
most powerful supercomputer in the world IBM's $100 million Roadrunner
system installed at the Department of Energy's Los Alamos National
Laboratory was officially named the most powerful and energy efficient
supercomputer in the world.

 http://www.top500.org/static/lists/2008/06/top500_statistics.pdf

The TOP500 list of the world's most powerful supercomputers was unveiled at
the International Supercomputing Conference in Dresden and proclaimed that
Roadrunner achieved performance of 1.026 petaflop/s-becoming the first
supercomputer ever to reach that performance milestone.

At the same time, Roadrunner is also one of the most energy efficient
systems on the TOP500.

Rounding out the top positions, all of which are in the US are the new IBM
BlueGene/P (450.3 teraflop/s) at DOE's Argonne National Laboratory .. the
new Sun SunBlade x6420 "Ranger" system (326 teraflop/s) at the Texas
Advanced Computing Center at the University of Texas - Austin .. and the
upgraded Cray XT4 "Jaguar" (205 teraflop/s) at DOE's Oak Ridge National
Laboratory.

The No. 6 system is the top system outside the US, installed in Germany at
the Forschungszentrum Juelich. It is an IBM BlueGene/P system and was
measured at 180 Tflop/s.

The No. 7 system is installed at a new center, the New Mexico Computing
Applications Center in Rio Rancho, NM. It is built by SGI and based on the
Altix ICE 8200 model. It was measured at 133.2 Tflop/s.

The Computational Research Laboratories, a wholly owned subsidiary of Tata
Sons Ltd. in Pune, India, installed a Hewlett-Packard Cluster Platform 3000
BL460c system. They integrated this system with their own routing technology
and achieved a performance of 132.8 Tflop/s which was sufficient for No. 8,
the survey noted.

The No. 9 system is a new BlueGene/P system installed at the Institut du
Développement et des Ressources en Informatique Scientifique (IDRIS) in
France, which was measured at 112.5 Tflop/s.

The last new system in the TOP10 - at No. 10 - is also an SGI Altix ICE 8200
system. It is the biggest system installed at an industrial customer, Total
Exploration Production. It was ranked based on a Linpack performance of
106.1 Tflop/s, according to TOP500.

Among all systems, Intel continues to grow, with Intel processors now found
in 75% of the TOP500 supercomputers, up from 70.8 % of the 30th list
released last November.

The US leads the world in supercomputer systems with 257 of the top 500.

The European share (184 systems - up from 149) is still rising and is again
larger then the Asian share (48 - down from 58 systems). Dominant countries
in Asia are Japan with 22 systems (up from 20), China with 12 systems (up
from 10), India with 6 systems (down from 9), and Taiwan with
3 (down from 11), according to the survey. In Europe, UK remains the No. 1
with 53 systems (48 six months ago). Germany improved but is still in the
No. 2 spot with 46 systems (31 six months ago), the survey found.

The group notes a number of other features from the survey:

* Quad-core processor based systems have taken over the TOP500 quite
rapidly. Already 283 systems are using them. Two hundred three systems are
using dual-core processors, only eleven systems still use single core
processors, and three systems use IBM's advanced Sony PlayStation 3
processor with 9 cores.

* The top industrial customer, at No. 10, is the French oil company: Total
Exploration Production.

* IBM held on to its lead in systems with 210 systems (42%) over Hewlett
Packard with 183 systems (36.6%). IBM had 232 systems (46.4%) six months
ago, compared to HP with 166 systems (33.2%).

* IBM remains the clear leader in the TOP500 list in performance with 48
percent of installed total performance (up from 45), compared to HP with
22.4% (down from 23.9). In the system category Dell, SGI and Cray follow
with 5.4 , 4.4 and 3.2 % respectively.

* The last system on the list would have been listed at position 200 in the
previous TOP500 just six months ago. This is the largest turnover rate in
the 16-year history of the TOP500 project.

With this survey, its 31st since 1993, the TOP500 began measuring computer
efficiency as well. The TOP500 most energy efficient supercomputers are:

* IBM QS22 Cell processor blades (up to 488 Mflop/s/Watt)

* IBM BlueGene/P systems (up to 376 Mflop/s/Watt)

* Intel Harpertown quad-core blades are catching up fast

* IBM BladeCenter HS21with low-power processors (up to 265 Mflop/s/Watt)

* SGI Altix ICE 8200EX Xeon quad-core nodes, (up to 240 Mflop/s/Watt)

* Hewlett-Packard Cluster Platform 3000 BL2x220 with double density blades
(up to 227 Mflop/s/Watt)

* These systems are already ahead of BlueGene/L (up to 210 Mflop/s/Watt).

* The average power consumption of a TOP10 system is 1.32 Mwatt and average
power efficiency is 248 Mflop/s/Watt.

* The average power consumption of a TOP50 system is 908 Kwatt and average
power efficiency is 193 Mflop/s/Watt.

* The average Power consumption of a TOP500 system is 257 Mwatt and average
power efficiency is 122 Mflop/s/Watt.
