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 facility also contains a petabyte High Performance Storage System (HPSS) that currently stores upwards of 29 petabytes of data. OLCF facilities are accessible through the Energy Sciences Network or ESnet. Resources of the Oak Ridge Leadership Computing Facility are dedicated to a limited number of high-impact, grand challenge scale projects.
The LINPACK performance gives some indication of performance for some real-world problems, but does not necessarily match the processing requirements of many other supercomputer workloads, which for example may require more memory bandwidth, or may require better integer computing performance, or may need a high performance I/O system to ...
However, other systems such as the K computer continue to use conventional processors such as SPARC-based designs and the overall applicability of GPGPUs in general purpose high performance computing applications has been the subject of debate, in that while a GPGPU may be tuned to score well on specific benchmarks its overall applicability to ...
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.
