You think WE'VE got sync problems?

Recommended Posts

Fascinating NYTimes article on

-  the need for nanosecond sync precision between distant computers connected via internet;

-  why NASDAQ is spearheading the effort (and has it working);

-  how it's useful for things as widely afield as World Cup Soccer;

-  how this has been a goal since the 1960s!

Cool article.  1/100 Billionth of a second is a huge leap in accuracy.  For comparison, Dante uses PTP (also used by some stock exchanges currently) which is accurate to 1 Microsecond (1/1,000,000 of a second).

I have always wondered why we don't use the Schumann resonance as the heartbeat of the world. We could easily adjust for the variables given that they are global.   I'll bet some of you did not know the world produces a beat every 7.8 ms

Not to mention it would be a part of US.... what we feel naturally (we cant hear that low but we sure can feel it!)

Not to be a PITA but 7.8 ms is 128 Hz, easily hearable. I think it's 7.8 Hz or a pulse every 128 ms. OK, now I've gotten my Sunday PITA cravings out of the way.

Best Regards,

It‘s 7.8 Hz, as Larry stated. There is no indication that this beat occurs at precise intervals, or even frequencies. And it varies depending on the time of year and on certain weather phenomena, such as lightning

Wouldn't the resonant frequency of the planet change with things like cyclic gravitational changes (i.e., lunar), density shifts from polar ice melting and subsequent evaporation, and even the burning of carbon extracted from under ground? 

 

Besides, we're talking a requirement for nanosecond precision among computers. 7.8 Hz seems precise only to a hundred ms.

Many of these high frequency traders are so obsessed with speed that they'll even position their offices close to the stock exchanges so as to minimize the travel time their internet connection has to go for a trade to be executed! Teeny tiny teeny tiny fractions of a second matter to these guys.

Ya, Michael Lewis talks about all this in his very-readable book, Flash Boys:

http://michaellewiswrites.com/#flash-boys

 

By "all this" I mean high-frequency trading. But back in the days a few years ago before the latest round of "even faster" "needs." There was some pushback against Lewis's book and apparently he did make a couple basically small mistakes, but a couple friends who are experts at this stuff (as in: one writes automated trading code, another is a biz professor) think a lot of the pushback was basically interested parties trying to discredit the book because it exposed some kinda crappy --but fascinating-- behavior. Here's what Lewis wrote about some of the response to the book. He's a very entertaining writer, btw:

And to keep this kinda close to JWS, there's a film being made from the book:

Jay, thanks for the link to the article!

FWIW, the point of ns precision is so trades can be accurately time-stamped, and then executed in order no matter how much latency exists between the trader and the exchange.

 

Will it work? Will sharks find a way to game the system? Yes and yes...

Actually it's two different problems :) The first one is the synchronization accuracy. The second one is a trusted timestamping mechanism that can't be played by the users. I can imagine some cryptographic approaches, but it's a hard problem and huge resources will be devoted to subvert it.

Maybe the small mistakes were intentional so as to mislead any potential competitors.

Awesome! I'll look forward to seeing this movie. 
I have a Math Degree plus a heavy background in Computer Science, so any of these technical trading kind of news do interest me.

Thanks Mono! That's pretty cool!

I highly recommend the book. Lewis is a former bonds salesman at Solomon Brothers (which he wrote about in Liar's Poker); that made him famous so he has some knowledge of the biz and good access to people. Also, he's an AMAZING writer. Insightful, dramatic, really funny. Several of his books have become movies (Moneyball, The Blind Side, The Big Short), but really, his books are super readable.
