HPE Frontier at the Oak Ridge Leadership Computing Facility is the world's first exascale supercomputer. Exascale computing refers to computing systems capable of calculating at least 10 18 IEEE 754 Double Precision (64-bit) operations (multiplications and/or additions) per second (exa FLOPS)"; [1] it is a measure of supercomputer performance.
As Moore's law nears its natural limits, supercomputing will face serious physical problems in moving from exascale to zettascale systems, making the decade after 2020 a vital period to develop key high-performance computing techniques. [8] Many forecasters, including Gordon Moore himself, [9] expect Moore's law to end by around 2025.
The encoding scheme stores the sign, the exponent (in base two for Cray and VAX, base two or ten for IEEE floating point formats, and base 16 for IBM Floating Point Architecture) and the significand (number after the radix point). While several similar formats are in use, the most common is ANSI/IEEE Std. 754-1985.

Noun adjuncts (nouns qualifying another noun) also generally come before the nouns they modify: in a phrase like book club, the adjunct (modifier) book comes before the head (modified noun) club. By contrast, prepositional phrases , adverbs of location, etc., as well as relative clauses , come after the nouns they modify: the elephant in the ...

Within an English-language book, the table of contents usually appears after the title page, copyright notices, and, in technical journals, the abstract; and before any lists of tables or figures, the foreword, and the preface. Printed tables of contents indicate page numbers where each part starts, while digital ones offer links to go to each ...
An English-language modernist group founded in 1914 that poetry based on description rather than theme, and on the motto, "the natural object is always the adequate symbol" [94] Ezra Pound, H.D., Richard Aldington: Dada: Touted by its proponents as anti-art, the Dada avant-garde focused on going against artistic norms and conventions [95]
