Discussion Overview

The thread discusses the announcement of the world's first petaflop supercomputer, focusing on its capabilities, implications for computational tasks, and humorous takes on its significance. The conversation includes technical aspects, speculative ideas about prime numbers, and reflections on the evolution of computing power.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Humor

Main Points Raised

  • Some participants note that Japan is credited with creating the first petaflop supercomputer, though its official ranking among the fastest supercomputers is still pending.
  • There are humorous remarks about the implications of such computing power, including jokes about sending numerous credit card applications to pets.
  • Participants question the existence of a "largest prime number," with some suggesting that finding such a number would require an extraordinarily complex computer.
  • Some contributions discuss the historical context of computing power, comparing petaflops to earlier milestones like teraflops.
  • Technical discussions arise regarding the feature sizes of transistors in modern supercomputers and the implications for processing speed and efficiency.
  • One participant humorously suggests that the largest prime number is a function of time, introducing a complex mathematical argument involving limits and Einstein's theories.

Areas of Agreement / Disagreement

Participants express a mix of humor and technical curiosity, with no clear consensus on the existence of a largest prime number or the implications of petaflop computing power. The discussion remains unresolved on several speculative points.

Contextual Notes

Some statements rely on assumptions about the nature of prime numbers and computational limits, while others reflect personal anecdotes about the evolution of technology. The discussion includes references to outdated posts and links that may not function properly.

The largest prime is a function of time. Setting the current time to t_0, we get \epsilon(t_0) = 2^{43112609} - 1, where \epsilon > 0 is the largest prime. Now apply A. Einstein's speed limit of 300 km/s to get a upper limit for the current time (which is no longer what the current time was when I began this post), in terms of the current space. We find that for each \epsilon, there is a \delta > 0 such that |f(x) - f(y)| < \epsilon. (See Introduction to Elementary Quantum Field Theory for Poets, by Gumm, page 486257). Now we use the standard mathematician's subterfuge of allowing zero to approach \delta from behind. This sneak attack will insure that \delta is circumspect while we let \epsilon \rightarrow 0. Thus the largest prime is zero.

Fortunately the adoption of the "one,two,many,lots" counting system allows to simply state that the largest prime has the value "lots" - in fact all primes except "many" have the value "lots"

The switching time is more a question of the capacitance of the junction which fortunately drops with feature size. Even desktop PCs now have <45nm features.

MosFets are more widely used, aren't they? There must be a rough way to characterize delay time with feature size. Something like t = f(RC+t_drift), using lumped values. What to do with power disipation--hold it constant with die area? And is there a lower bound on bias voltage for mosfets? It hadn't occurred to me to ask if there were a lower limit on flipping channel. Deposition thinkness would effect both R and C. Has it remained fairly constant as of late?
