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.

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.
