The modern doctrine of psychophysical parallelism
is not appreciably different from this theory of the Cartesian school.
Distinction between the sterility of first crosses and of hybrids -- Sterility various in degree, not universal, affected by close interbreeding, removed by domestication -- Laws governing the sterility of hybrids -- Sterility not a special endowment, but incidental on other differences -- Causes of the sterility of first crosses and of hybrids -- Parallelism between the effects of changed conditions of life and crossing -- Fertility of varieties when crossed and of their mongrel offspring not universal -- Hybrids and mongrels compared independently of their fertility -- Summary.
Hybrids from two species which are very difficult to cross, and which rarely produce any offspring, are generally very sterile; but the parallelism between the difficulty of making a first cross, and the sterility of the hybrids thus produced--two classes of facts which are generally confounded together--is by no means strict.
In this way the curious parallelism
to animal motions, which was so striking and disturbing to the human beholder, was attained.
Around a great fire which burned on a large, circular flagstone, the flames of which had heated red-hot the legs of a tripod, which was empty for the moment, some wormeaten tables were placed, here and there, haphazard, no lackey of a geometrical turn having deigned to adjust their parallelism
, or to see to it that they did not make too unusual angles.
The forest was here almost composed of the kauri; and the largest trees, from the parallelism
of their sides, stood up like gigantic columns of wood.
Their success lay in their parallelism
to the course of thought, which found in them an unobstructed channel; and the wonders of which they were the visible conductors seemed to the eye their deed.
which occur in the so-called Apology of Xenophon are not worth noticing, because the writing in which they are contained is manifestly spurious.
To bridge the gap, this proposal tackles a grand challenge: How do we design an algorithmic foundation that enables the development of all necessary pillars of big and fast data analysis This proposal considers three pillars: 1) Parallelism
: There is a fundamental tension between data parallelism
(for scale) and pipeline parallelism
(for low latency).
correct the parallelism
in items joined by both/and, either/or, neither/nor, or not only/but also; and
Seven Concurrency Models in Seven Weeks: When Threads Unravel is for expert programmers who want to understand the issues with traditional threads and locks development, and want to exploit a computer's GPU parallelism
to produce better-quality code.
Among his topics are parallel forms of parallelism
, applications of parallelism
by task, first-order and second-order meta-algorithmics, and building more robust systems.
