High-performance computing (HPC) as a term arose after the term "supercomputing". [3] HPC is sometimes used as a synonym for supercomputing; but, in other contexts, "supercomputer" is used to refer to a more powerful subset of "high-performance computers", and the term "supercomputing" becomes a subset of "high-performance computing".
Frontier is anticipated to be operational in 2021 and, with a performance of greater than 1.5 exaflops, should then be the world's most powerful computer. [91] Since June 2019, all TOP500 systems deliver a petaflop or more on the High Performance Linpack (HPL) benchmark, with the entry level to the list now at 1.022 petaflops. [92]
The Blue Gene/P supercomputer "Intrepid" at Argonne National Laboratory (pictured 2007) runs 164,000 processor cores using normal data center air conditioning, grouped in 40 racks/cabinets connected by a high-speed 3D torus network. [1] [2] A supercomputer is a type of computer with a high level of performance as compared to a general-purpose ...
OLCF's fastest computer, Frontier, is a 1.102 ExaFLOPs HPE OLCF-5 supercomputer with a CPU/GPU hybrid architecture. The combination of CPUs and GPUs will allow Titan and future systems to overcome power and space limitations inherent in previous generations of high-performance computers.
The CoCom and its later replacement, the Wassenaar Arrangement, legally regulated, i.e. required licensing and approval and record-keeping; or banned entirely, the export of high-performance computers (HPCs) to certain countries. Such controls have become harder to justify, leading to loosening of these regulations.
The SGI high-performance computer is a 5.34-petaflops system, meaning it can carry out 5.34 quadrillion calculations per second. The data storage system for Cheyenne was integrated with NCAR's existing GLobally Accessible Data Environment (GLADE) file system.
