Computing Limit – Computerphile
Computing Limit – Computerphile
Just how far can we go with processing speed? Physicist Professor Phil Moriarty talks about the hard limits of computing.

I want to become a expert in harry potter for some reason..
I love inforMeHtion
Discover Computing from the guidance of the Quran by Dr Zaid Kasim Ghazzawi .π
This is awesome
Thanks for the memorable uncertainty principle demonstration. It also works in human communication: the attention span of your audience defines the complexity of the message you can convey.
What a self obsessed fanny.
Video on Fredkin gates…then a video on quantum gates.
Is no one really gonna comment on the fact that we got an Irish professor named Moriarty LOL?!!!
I want to change the way I say information to the way this guy does.
Whoa that’s ridiculously cool
Seeing this guy on Computerphile is so surreal after seeing him in Armored Skeptic’s "Answers for SJWs"
There are quite a few theoretical ways to not only break through most physical limits of computation but also to solve uncomputable functions such as the halting problem or the Busy Beaver function
Not exactly sure what "energy" dissipation corresponds to "information loss". I can conceive a perfect CMOS AND that dumps stored charge on internal nodes to ground through ideal zero resistance "on" transistors at logic transitions. That is information loss without energy dissipation. I think the concept of "entropy" is used differently in physics/thermodynamics and information theory and the two usages are muddled here.
Wow, I got goosebumps at the end of the video when you explain how far away we actually are from the computational limit.
Nice (or accidental?) Erotomania reference? π
Mathematically speaking, this reminds me of inverse functions. The system is reversible if every final position can be paired with at most one initial condition. Which in math terms is like saying the mapping from the initial condition set to the final condition set must be injective (i.e. must be a monomorphism).
13:24 AMD, Cray to build 1.5 exaFlop "Frontier" supercomputer for Oak Ridge National Lab, it arrives at the lab in 2021.
NICE
It’s not just me, there’s something weirdly sexy about this video, right?
If i dont code it i cant understand it…….Seems like einstines statement "If you cant explain it in simple way means you have not understood it "
I have observed the most efficient computer would be a light beam computer; or, an atomic computer utilizing trittium that is utilized in watches.

He’s quite an annoying man.
PS look at the guitar hidden in plane sight in his office, just so we all know what a free spirit he is.
"THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
This guy’s infinite enthusiasm and unbounded love for his subject matter is self-evidently just way off the charts. See what I did there? Infinite and unbounded? Off the charts? Those things are just as true in terms of what he’s talking about as they are of how passionately he tries to get things accross It’s just that he does it all so much more spontaeously and infectiously than I ever could. Simply awesome.
Moore’s Law forever!
Thats no NAND gate its an AND gate
Gates that use field-effect transistors consume energy only when switching. How that energy loss applies in this case?
Thats why you GO BEYOND. There’s always improvements to be made, nothing is ever perfect.
Do we have exoflops now?
ok can he play smoke on the water or metallica Wherver i may roam that be great hahaha
13:10 – 10 to 15, or 10e50? We already have 15 operations per second π
"THE DEATH OF EXPERTISE"
can’t find ElectricEngineeringPhile. does anyone have the youtube link?
I really enjoyed this one. Cheers!
Ointments
This is really really cool! Computation without energy loss would be amazing!
I thought this was gonna be about how computers compute mathematical limits
I have been eating up videos from this channel. Not a clue for most of it but I love it, cheers π
Love this man. Great teacher. Wish I could attend.
This man has a truly awesome gift for information transfer! I envy his students.
Does this only apply to a theoretical quantum computer with qbits? Or is it only a theoretical classical computer?
Dear Computerphie team. I have added accurate English captions as well as Russian captions about a year ago. Could you please review and perhaps publish them, should you be satisfied. Thank you!
Just having a cleaning time at home but these matters never get dull really π
Ill solve:
The computing speed limt
The computing lightspeed
The computing c
Use C!!!!
Perfect fredken gates can exist with superconductors. No resistance, no energy loss to heat, no information loss
My upvote lost most of the information in how much I enjoyed this talk…
But would 10^50 Flops be enough to simulate a universe π€?
But can it run crysis?
Sorry I had to. Imagine gaming in a dual blackhole Intel cpu.
Computer unlimits
But if the limit is for consecutive operations, well, we ran up against engineering limits for those a long time ago and the super computers he mentioned have limits that are based on assuming that a large number of instructions can go on in parallel without communication between them.
