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.
Aurora is an exascale supercomputer that was sponsored by the United States Department of Energy (DOE) and designed by Intel and Cray for the Argonne National Laboratory. [2] It was briefly the second fastest supercomputer in the world from November 2023 to June 2024.
Hewlett Packard Enterprise Frontier, or OLCF-5, is the world's first exascale supercomputer.It is hosted at the Oak Ridge Leadership Computing Facility (OLCF) in Tennessee, United States and became operational in 2022.
In 2004, two years after the book was published, Peter Culicover wrote: The Cambridge grammar of the English language (CGEL) is a monumentally impressive piece of work. Already published reviews of this work do not overstate its virtues: 'a notable achievement'; 'authoritative, interesting, reasonably priced (for a book of this size ...
Construction grammar (often abbreviated CxG) is a family of theories within the field of cognitive linguistics which posit that constructions, or learned pairings of linguistic patterns with meanings, are the fundamental building blocks of human language.
All books were moved to subpages of Wikipedia:Books/archive at the end of June where they remained for a month to allow users to keep books in userspace and allow for refunds after namespace deletion. On 3 August 2021, all books were deleted. For details of how to restore a book after deletion, see: Wikipedia:Books/archive
