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.
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. The cost was estimated in 2019 to be US$500 million. [3]
Hewlett Packard Enterprise El Capitan is an exascale supercomputer, hosted at the Lawrence Livermore National Laboratory in Livermore, California, United States, that became operational in 2024. It is based on the Cray EX Shasta architecture. El Capitan displaced Frontier as the world's fastest supercomputer in the 64th edition of the Top500 ...
As of November 2024, Frontier is the second fastest supercomputer in the world. It is based on the Cray EX and is the successor to Summit (OLCF-4). Frontier achieved an Rmax of 1.102 exaFLOPS , which is 1.102 quintillion floating-point operations per second, using AMD CPUs and GPUs .
National standard format is yyyy-mm-dd. [161] dd.mm.yyyy format is used in some places where it is required by EU regulations, for example for best-before dates on food [162] and on driver's licenses. d/m format is used casually, when the year is obvious from the context, and for date ranges, e.g. 28-31/8 for 28–31 August.
As of 2024, the United States has the highest number of systems with 173 supercomputers; China is in second place with 63, and Germany is third at 40. The 59th edition of TOP500, published in June 2022, was the first edition of TOP500 to feature only 64-bit supercomputers; as of June 2022, 32-bit supercomputers are no longer listed.
In May 2024, Musk predicted that AI will make most jobs obsolete, requiring a high universal income. [22] In June 2024, the Greater Memphis Chamber announced xAI is planning on building Colossus, the world's largest supercomputer in Memphis, Tennessee. [23] After a 122-day construction, the supercomputer went fully operational in December 2024.
The last modification date stamp (and with DELWATCH 2.0+ also the file deletion date stamp, and since DOS 7.0+ optionally also the last access date stamp and creation date stamp), are stored in the directory entry with the year represented as an unsigned seven bit number (0–127), relative to 1980, and thereby unable to indicate any dates in ...
