Bandwidth Challenge Results
the 1st sandman writes "SC2005 published some results of several challenges including bandwidth utilization. The winner (a Caltech led team of several institutes) was measured at 130 Gbps. On their site you can find some more information on their measurements and the equipment they used. They claimed they had a throughput of several DVD movies per second. How is that for video on demand!"
how long before these ultra-high speed networks are rolled out the home users?
- My question is: Can Slashdot be Slashdotted? -
"They claimed they had a throughput of several DVD movies per second. How is that for video on demand!""
How many Library Of Congress'es is that?
The Bandwidth Challenge, sponsored by the good fellows at the MPAA and RIAA. I think they forgot to put their logos on the sponsor page.
I love arbitrary metrics..

Given you might need to serve a few thousand people an hour (or more?), I'd say it's still got awhile to go. Kinda sobering, when you think about it. Shiny discs and station wagons are going to be around for awhile.
..don't panic
I'm very happy to see the second place went to my coworkers at PNNL. I don't know about Caltech's, but PNNL was to disk as well. Impressive feats all around.
I don't want to denegrate the Caltech crew either, as I know Stephen Low and find that he's one of the nicest guys I've ever gotten to work with.

in this case, several dvd being equal to 2. (130gbps / 8bit/Byte / 8GB/movie ~= 2)
figure.

Don't tell the MPAA - they already tell people you can download an entire DVD movie over a 56K phone link in 15 minutes - imagine what they would tell people how much money they lose per second with this new high speed connection!

They claimed they had a throughput of several DVD movies per second.
In other news, the MPAA released a statement today saying...
"They've Gone Plaid!"
" i r 1337. j00 a l0z3r "
That talk kinda makes you cry, doesn't it?
That's right..cry those nerdly tears
Or Libraries of Congress per second. DVDs per second isn't a useful rate, unless you're transferring lots of DVDs in a series - which few people do. The much more interesting bandwidth unit is "simultaneous DVDs", multiples of 1.32MBps, 1x DVD speed (9x CD speed). 130GBps is something like 101KDVD:s, which means an audience could watch 101 thousand different DVDs on demand simultaneously over that pipe. That's probably enough for most American cities to have fully interactive TV.
... you could transfer the entire library of quality hollywood movies in 4 seconds.
What do we do next ?

I'm more interested in the media in which they'd write to at those speeds.
I am downloading the SWG Trial at 80kb/s on "high-speed" internet. And for the record, my cable modem was faster 4 years ago than it is today, on average. If we are making progress, it sure as hell isn't in the commercial sector.
That's nice, but what is it in Libraries of Congress per microfortnight?
That was a credit to the Hudson Bay Fan Company for keeping all that smoking data cool.
But don't tell the RIAA or the MPAA, they'll have a press release out yet tonight about how much they lost to piracy. But I'll bet its never crossed their minds that if they'd quit treating the customer like a thief, and give him an honest hours entertainment for an honest hours wages, plus letting us see how much the talent got out of that, we'ed be a hell of a lot happier when we do fork over.
We don't like the talent to starve when they've a million seller, and nearly $20 for a friggin cd is outragious.

This is nothing but an impressive statistic until ISPs provide this kind of bandwidth into homes (the infamous "last mile" connection). Not to mention that even the fastest hard drives available to consumers can't write data this fast.
Quantum mechanics: the dreams that stuff is made of.
How many Libraries of Congress per second?
Let's see how they handle a Slashdotting...
"a throughput of several DVD movies per second"
How many trucks per hour, loaded with DVDs, speeding down the highway is that?
"But don't tell the RIAA or the MPAA, they'll have a press release out yet tonight about how much they lost to piracy. But I'll bet its never crossed their minds that if they'd quit treating the customer like a thief, and give him an honest hours entertainment for an honest hours wages, plus letting us see how much the talent got out of that, we'ed be a hell of a lot happier when we do fork over."
Since we're doing another "I hate the RIAA/MPAA/Some game producer" rant tonight. When exactly was the demarcation point between "Like a thief/not like a thief" and "Price I like/ price I don't like" and Piracy. Or to put it in an "chicken/egg" context. Which came first? As for what the talent makes? Maybe the "talent" feels that it's none of your business. How much do YOU make?
"We don't like the talent to starve when they've a million seller, and nearly $20 for a friggin cd is outragious."
Not buying things...consumer, does amazing things for both situations. So why are you all still buying...and complaining?
If only I had a HDD big enough to download the internet auuuuuuuugh downloading porn at the speed of liiiiiiiiight!
Instead of sending lots of packets filled of garbage or insults, you could slam your enemies with entire copies of Zoolander!
Imagine you "owned" O'Hair Int'l and the Atlanta airport, two of the busiest airports in America.
Imagine you had as many big planes as possible taking off from each airport and landing at the other every day.
Imagine they were all filled with hard disks or DVDs.
Now THAT is a lot of bandwidth.
Latency sucks though.
The moral of the story:
Bandwidth isn't everything.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
Here I was expecting to read about one of the BSDs again (like when they used NetBSD to break the Internet2 Land Speed Record), but it looks like this time they used an "optimized Linux (2.6.12 + FAST + NFSv4) kernel". I'm not well informed on speed records held by various versions of the Linux kernel, so maybe someone else can tell us whether this is something special for Linux or more run-of-the-mill. I had the impression that professional researchers usually prefer the BSDs for this kind of work. Will this put Linux on the map for more high-end research like this?
Impressive work, either way.
good luck slashdoting this one!
Rumor has it that Sony is planning on releasing the next version of their rootkit for this infrastructure. The new version will all users to call a simple API. I for one thank Sony for inventing a disabler of any new threatening technology.
connectionListener();
sendSpam();
startDOS();
Proof by very large bribes. QED.
I'm looking through these charts and I am not finding an important number, how far the signal can be sent at that rate before it starts dying. Repeaters could be responsible for keeping this in vaporworld.

The L1 cache on a P4 has a latency of 2 [or 3] which yields one 16 byte read every 2 cycles or about 1.6Ghz * 128 = 204.8Gbps :-)

Someday, I'll have a real sig.
So the actual speed was faster.
Why not TeraGoatsesPerSecond to measure the hole bandwidth so that we can more easily visualize it?
And, at least the size is standard.
This is not a dream, not a dream...we are transmitting from the year 1-9-9-9.
130Gbps and they still use jpeg to (badly) compress their graphs.
When there exists a business model that profits from rolling out these to the home users.
That's almost as fast as the movie industry is generating crappy movies to download!
This competition becomes less and less relevant as it was meant to drive better ways to utilize the network and find application to use that bandwidth. For utilization, as long as you got enough CPU and parallization then you can fill the pipe - last few years of this competition has been just doubling up CPU, find a big long pipe, pump it thru, wash/rinse and repeat. And for applications, VOD stuff and the likes cannot be done because of last mile, not because of lack of technology. I'm not sure if the competitions achieved what they wanted last few years.
So how long would it take for me to use up my monthly quota of 10Gig with bandwidth like that... ;)

Probably one of those RAM "hard drives" I saw on a slashdot article a while back. IIRC they have 4GB capacity max right now (four 1 gig sticks of ram)
e wsID=1176
While googling in an attempt to find what I was thinking about, I found this article from a year ago about a HUGE one of these bought by the US government for 'database crosschecking' (Spying on people in real time, for those of you wearing your tinfoil hats)

Enjoy.
It would be nice to know what each group of hardware is doing in this setup. What purpose do all the different servers have on the system? Also, there is a lot of storage on this setup, however it's spread all over the place. They have 4x300GB hard drives in each of the 30 Dual Opterons, one 36.4GB hard drive in each of the 40 HP servers, 24 hard drives on the Sun server, more hard drives on the IBMS, and even more on the Nexsan SATABeast. Any idea what each cluster of servers does?

You get random access to the whole movie for 24h hours for about $4
A good deal I think and regularly watch a movie.
There are places where the networks are not touching,and there are places where they are-Boeing's Lori Gunter
They claimed they had a throughput of several DVD movies per second. How is that for video on demand!
I can't answer the question until I know WHICH several movies.
God, i realy hope a spammer doesnt grab one of these....
I had a (very small) amount of code in the Argonne entry, and they were writing to disk. (In fact, I hear that's why Argonne's number was low - the disks they were supposed to write to were doubled-booked, so they had to find a replacement set of destination servers and it wasn't nearly as good as the original plan)
/dev/zero on one machine to /dev/null on another, or maybe even writing to a big ram disk, but now it's end to end - how fast can you get data off a remote server and on to the disks on the show floor, so it's obviously about clusters of servers, multiple data streams, and multiple destination servers.
The bandwidth challange used to be about copying from
