Plotted here is logarithmic parallelization vs linear speedup. If exactly 50% of the work can be parallelized, the best possible speedup is 2 times. If 95% of the work can be parallelized, the best possible speedup is 20 times. According to the law, even with an infinite number of processors, the speedup is constrained by the unparallelizable ...
In computer science, a scale factor is a number used as a multiplier to represent a number on a different scale, functioning similarly to an exponent in mathematics. A scale factor is used when a real-world set of numbers needs to be represented on a different scale in order to fit a specific number format .
There are a number of technical challenges in building a large-scale quantum computer. [91] Physicist David DiVincenzo has listed these requirements for a practical quantum computer: [92] Physically scalable to increase the number of qubits; Qubits that can be initialized to arbitrary values; Quantum gates that are faster than decoherence time
[50] [23] Some upper limit on speed may eventually be reached. Jeff Hawkins has stated that a self-improving computer system would inevitably run into upper limits on computing power: "in the end there are limits to how big and fast computers can run. We would end up in the same place; we'd just get there a bit faster. There would be no ...
The sudden success of deep learning in 2012–2015 did not occur because of some new discovery or theoretical breakthrough (deep neural networks and backpropagation had been described by many people, as far back as the 1950s) [i] but because of two factors: the incredible increase in computer power (including the hundred-fold increase in speed ...
In computer operating systems, memory paging (or swapping on some Unix-like systems) is a memory management scheme by which a computer stores and retrieves data from secondary storage [a] for use in main memory. [1] In this scheme, the operating system retrieves data from secondary storage in same-size blocks called pages.
The intensity of a pixel is expressed within a given range between a minimum and a maximum, inclusive. This range is represented in an abstract way as a range from 0 (or 0%) (total absence, black) and 1 (or 100%) (total presence, white), with any fractional values in between.
Optical drive technology was still limited in spindle speed, so playing an audio track from the game CD meant that the system could not access data again until it stopped the track from playing. Looping , the most common form of game music, was also a problem as when the laser reached the end of a track, it had to move itself back to the ...
