    Actually, this is 100 P- DL -FLOPS (DL=deep learning meaning 8-bit with shared exponent). Although the second generation (and presumably third gen) TPU can also do 16-bit floating point (and maybe FP32) for training, the quoted (i.e., not-to-be-exceed) number is the deep learning flops for inference/recall...

    In contrast, a typical supercomputer generally describes their performance for IEEE 64-bit double precision floating point (FP64)

    No doubt the later generations of TPUs will support some reasonable level of performance of 16bit (and maybe 32-bit) FP, but not likely at the peak rate for 8-bits.

    I also doubt they would even bother to support FP64 on a deep learning chip since FP64 is mostly used for discrete time dynamical simulations and other forms of finite element analysis where you want to limit error accumulation due to precision issues.

    The value proposition of 'C' was that you could efficiently program near the metal.

    Instruction sets and micro-architectures co-evolved with 'C' along those dimensions of efficiency. All those extra operators idioms like "+=" and "++" were inherited from its predecessor B** (well actually, adapted from "=+" because of the lexical ambiguity) to match accumulator style instructions common in contemporary instruction sets and to reduce compiler complexity (using these kind of idioms, even a memory/perf constrained compiler with limited optimization capabilities could get close to metal performance). As compiler technology advanced and people wanted to write higher level code, C (and C++) continued to have these operator features as boat anchor legacy.

    STL and templates basically were an idea to bring generic programming concepts to C. Initially implemented by the c-front pre-processor, initial implementations were forced to live with the limitation of available primitive linker and debugger capabilities which were created for C and other languages w/o these new capabilities. The early problems with templates stems mostly from practical implementations having legacy linkers and debuggers as boat anchors.

    The truth is that efficiently implementing the programming idioms of the day is important for any language to remain relevant. Because of legacy, retro-fitting new idioms into older frameworks is sometimes painful, but it the easy way to allow you to incrementally use new features whilst still using old code bases.

    ** I believe Thompson put those extra operators into 'B' with Ritchie's approval, so maybe it was Kernighan who complained about too many operators and got rid of B's comparison assignment operators (e.g., '=' and '=>=') in 'C'

  11. Re:Timekeeping. on Yale Physicists Find Signs of a Time Crystal (yale.edu) · · Score: 1

    Do DTCs break time symmetry because of their local (in time) -based oscillations that are not atomic, but rather sub-atomic?

    *Crystals* break local symmetries. It has nothing to do with atomic vs sub-atomic. Normally the laws of physics don't respect a specific orientation, or phase, but in a crystal, for some reason a system can be in a state that prefers a particular set of orientations or phases, that is what we call a crystal.

    Why do we have a constant velocity along the time axis in this universe (under non-relativistic conditions)?

    If you want to be pedantic, dt/dt (the change in the rate of time over the change in the rate of time) is always constant. "We" only assume that other observers see our time the same as "we" do. It turns out not to be the case (even in non-relativistic conditions), everyone's view of time is different because there is no preferred reference frame to measure it.

    Maybe we oscillate between Big Bangs and Big Crunches over the billions off years... Oh yeah, there is no time before the Big Bang, which started the clock. Bah! I'll stick to crystals.

    We clearly do not have enough understanding of physics to decide this question, but if you believe in the so called lambda-CDM model of the universe, by definition physics can't describe a time "before" the big bang. If, however, I had to hazard a guess, I'd say lambda-CDM model isn't going to last very long. There are already significant discrepancies and ongoing observation surveys that are looking for dark matter and dark energy signatures are likely to find interesting data that will require new updated models...

  13. Re:Timekeeping. on Yale Physicists Find Signs of a Time Crystal (yale.edu) · · Score: 3, Interesting

    The difference between an oscillator and a time crystal, is that an oscillator generally has a resonant spatial structure (usually a spatial crystal or atomic band-gaps) that captures energy (near a resonate frequency or harmonic) and converts it to work near a preferred oscillation frequency. Since the oscillation is actually physical transition with inefficiencies mean that there is a limited 'Q' factor

    A time crystal on the other hand is an emergent temporal sub-harmonic structure. Since a time crystal does not require a spatial structure to convert energy into work there is the potentiality for them to have a much better 'Q' factors.

    The interesting thing about time crystals is that locally they break time-symmetry like spatial crystals break local spatial symmetry.

    Spatial crystals break local spatial symmetry so spatial interactions (translational or rotational) between particles and stable spatial crystals can change momentum of the particles in stable ways because of conservation of momentum (which is basically of how typical electronic oscillators work) being an emergent property of spatial symmetry (Noether's theorem)

    Time crystals break local temporal symmetry so temporal interactions between particles and stable time crystals can directly change the energy of the particles in stable ways because of conservation of energy being an emergent property of temporal symmetry.
