GPU Power outperforming CPU Power

According to the latest
F@H statistics
, graphics cards processors are pretty much
outperforming traditional CPU’s.
The current factor is about 75 GFlops on GPU against an average of
1GFlops on a CPU. (this varies because of very old processors and
modern processors with about 14 GFlops).

Anyway at the moment we see 370 GPUs doing the same amount of work
as 29000 CPUs. This is really great for the F@H project, although the GPU
cores at the moment are only capable of doing basic calculations
with the gromacs application. Other applications have to be heavily
rewritten, and/or are not able to run every calculation on GPUs and
therefore have to use the main CPU for those parts of the
calculation.

Photokina Super Tele Lens1700mm

Finally there’s something for the real
tele-photographer enthusiast.Ladies and Gentleman,
the worlds “last civilian” tele-lens for photographers.

1700mm focal length
luminous intensity 1:4
weight 256 kg

And some overview figures to see the whole “monster” at once:

super-tele-side
If you’re still looking for something “bigger” I can only suggest
to hijack the hubble space telescope, or google the net for earth
based extremely large telescope projects like thess one.

RC-Flight next generation

Some of you might remember
cable-remote-controlled cars, with even fixed or wire- pulled
steering.
And our highest dreams would be to be able to afford the money to
buy a remote controlled plane one fine day.Then came the day we had enough money to do so. And we didn’t allow
our kids to fly by themselves because “this toy is just for daddy”
and much to expensive if it crashes.
Yeah, someday later we crashed it by ourselves…. done.

Kids nowadays will come up with this, and just keep smiling at us,
dinosaurs, and don’t let us play because we might not understand
how, cause we’re so “seventies ?” Winking

And for those people of you that didn’t like the sound of the first
video, here’s something more scary….. Winking

Science Sports – Calculate PI

And another game for the next birthday
party:dart-pi
Let your guests calculate Pi by playing some rounds of
“darts”.

Do this by targeting the blue shaped square on the above figure.
And then simply count the darts you are throwing and that will be
inside the square, and additionally the darts that miss the board
and hit inside the marked blue area.

And after a few rounds, let’s say 1.000-100.000 Winking should be enough
to see some good results.
Now use this formula:

dart-pi-formula

A small hint for the frustrated, invite people that are able to aim
the upper left square, but are not so much pros that they will
always hit the board only.

Join Stardust@Home

Following the search for
extraterrestrial life with the SETI@HOME project and
huge amounts of further other projects
that are being worked on
using a cross-platform distributed computing architecture named
BOINC, there is now a new
project for volunteer participants to help work on:
Stardust@HOME

The spacecraft Stardust
was launched in 1999 to catch dust particles of comet Wild 2.
Therefore a substance called aerogel was invented
which is capable of catching high speed dust particles and softly
de-accelerate them so they will stuck inside the aerogel and can be
brought home to mother earth without any damage.
aerogel1
The aerogel which holds the dust particles “maybe from beginning of
the universe” is now to be inspected by “you”. Since it’s almost
impossible to find a needle inside of a soccer-field, you can
imagine the work that has to be done to find particles from outer
space sticking inside the aerogel. So what has been done to solve
this problem ? “Simply”: The aerogel is scanned layer for layer by
a microscope and the images are stored in a database. From this
database you’re now able to access pre- and past-focussed images
and search for dust impacts.
aerogel-profile
Once you finished a short tutorial and training, you’re presented
new images to analyze mixed with already known images to test your
discovery “or spamming” skills.
Wow, that’s what I call science by wire…. Winking

VIA invents the “TreeMark”

VIA has just invented a formula to
measure ecology of processors.
In it’s “TreeMark” called index, VIA’s new C7-D processor
takes
a top position, by
only needing four trees over 3 years to compensate
the CO2 produced by the energy consumed for the processors
operation.

Compare your own
processor, it’s just that easy:
viaformula
1 Assuming 27% standby mode, 3% sleep mode, 67%
idle mode, 3% performance  mode
2 Global
average carbon intensity of electricity
3 Based on
average broad leaf tree

viac7dOther “TreeMarks” ordered by their integer performance:

35 Trees = Mac Pro Quad Xeon 3,0 [115,3
SPECint_rate_base2000]
73 Trees = 2 x Xeon DualCore 2,8 [ 59,0
SPECint_rate_base2000]

53 Trees = 2 x

Nostalgically – Dark Faith of 3rdMillenium Projects

Browsing through my computer library
archives, I rediscovered some demo screenshots of a computer
role-playing-game that I was programming together with Sun(Gerd) as
graphical artist, Loki(Reyk) and Bernhard for background story and
concept.Within 3 years, and only 1 programmer, we didn’t achieve a finished
playable game, but anyway we all learned a lot doing this Dark
Faith Game for he 3rd Millenium Projects initiative.

Click on
the image above or here to see further screenshots of “our”
programming and “graphics design” progress.

Back right now, Sun is heavily creating in Blender again, as you
can read in his blog.

The more interesting thing is, that all project members changed to
intel Mac’s by this year. Laugh
