Single computer breaks PetaFLOP barrier

Please confine these topics to things that would be of general interest to those who are interested in FAH which don't fall into any other category.

here's another link: http://fah-web.stanford.edu/cgi-bin/main.py

That result (4 Million+ pts) was from just a few days... about 4 days I think, forgot the exact time frame...
When the scores were "fresh" and the stats pages gave more detail, you could see it ramp up and back down
like a bell curve, or a square-wave.

No one who knows anything has said anything- Dang!
By chance I happened to have the daily stats from "that super computer" ;)

Thanks theMASS,
That's great. Hard data trumps swiss-cheese memory.
Looks like the "speed bump" was about 3 million points between 11/21 and 11/26- 2007.
Not bad.
They went into that time slot with a million pts. already, so my guess was totally off.
Hope I didn't spill some beans.
Maybe they'll do it again, and talk some of their buddies with supercomputers into doing it, too.

Wild-@$$ guess #2:
Fermilab's effort was nothing officialy coordinated, they just had to shut down their accelerator for a few days to sweep out the cigarette butts, or whatever, so their mainframe wasn't busy and they decided (down at the pub) to take 'er out for a spin and see what she'd do...
Nah, that can't be it.
Can it?
:roll:
I wonder, are you an Ex-pat Aussie? :D
Love the Guess 2 scenario and who knows? maybe an element of truth? :D

This might sound very simplistic but, wouldn't it be a small amount of money to power a Super Computer for folding than developing and dropping bombs? Wouldn't it make sense to spend money for extending lives than shortening them? :roll:
Still new at this

You're preaching to the choir here, my friend.
I doubt that many folks here are of the mind to be flinging bombs about.

have you seen some of the garbage on BOINC? SeTI, one is even looking for a second pi. another trying to play a row of queens in chess. another one trying to find a new prime #. very critical stuff. there are some useful ones up there, but come on.

Now, now. You don't need to be critical of the choices that other people make. (Aren't you the guy who chooses to believe that you might have done something that causes your computer to overheat?)

A new prime number can lead to significant advances in encryption methods.

The Roadrunner is a sexy beast!

At cost estimates of between $133-200 M ...yea...they're not going to be running F@H any time soon. Besides, because of their hybrid architecture (AMD Opteron I/O processors, PowerXCell for the computations), if people are having gripes about F@H on Solaris/SPARC as it is, I DOUBT that anything's going to be done to port F@H over specifically for the Roadrunner.

But needless to say, the Roadrunner is scheduled to do MORE nuclear simulations (you know...cuz as in all of the prior ASC computers can't do enough of it between LLNL, LANL, and SNL), some human genome stuff, some geophysics stuff (I forget what exactly), and climate modelling.

(Actually, if you read some of the tech briefs and some of the accomplishments that the Roadrunner has already made, they're simluating stuff at the atomic level, and to think that F@H might be, at best, at the molecular level. HA!)

It never ceases to amaze me though and fascinate me that people already develop programs for this sort of stuff, and how computationally demanding it is.

Personally though, I think that the supercomputer that I still favor the most is the TACC Ranger (currently #6 on the Top500 IIRC). It feels more like "home" to me.

And at ONLY $30M, and achieving a peak of roughly half of what the Roadrunner is capable of, it's a freakin' sweet deal!

folding is making my computer overheat. i have this great 1.6ghz dual core laptop and i can only run folding at 40% of cpu because even there its HOT. ive blown it out through the fan and vent side with the heat sink and a lot came out but not enough apparently. no way i trust myself enough to open it up. if it was a desktop sure, but no chance im cracking open a laptop...... but what are you talking about? how coudl ---I--- make the computer overheat?

Well...I don't know if it's so much about "entering the computing age".

As a mechanical engineer, we've often had to simplify our problems LONG before computers were invented just because if we were to actually do it right/properly, the computations would essentially never end.

And as Jonathan Schwartz says, HPC is one of the areas in computing where we will consistently outstrip our demand for computational power, and it is also one of the (few) areas where our demand for it will ALWAYS outpace what Moore's Law allows.

Horray for quantum computing.
