High-performance technical computing (HPTC) is the application of high performance computing (HPC) to technical, as opposed to business or scientific, problems (although the lines between the various disciplines are necessarily vague). HPTC often refers to the application of HPC to engineering problems and includes computational fluid dynamics, simulation, modeling, and seismic tomography (particularly in the petrochemical industry).

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there have existed supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS).
High-performance computing (HPC) uses supercomputers and computer clusters to solve advanced computation problems.
David A. Bader is a Distinguished Professor and Director of the Institute for Data Science at the New Jersey Institute of Technology. Previously, he served as the Chair of the Georgia Institute of Technology School of Computational Science & Engineering, where he was also a founding professor, and the executive director of High-Performance Computing at the Georgia Tech College of Computing. In 2007, he was named the first director of the Sony Toshiba IBM Center of Competence for the Cell Processor at Georgia Tech. Bader has served on the Computing Research Association's Board of Directors, the National Science Foundation's Advisory Committee on Cyberinfrastructure, and on the IEEE Computer Society's Board of Governors. He is an expert in the design and analysis of parallel and multicore algorithms for real-world applications such as those in cybersecurity and computational biology. His main areas of research are at the intersection of high-performance computing and real-world applications, including cybersecurity, massive-scale analytics, and computational genomics. Bader built the first Linux supercomputer using commodity processors and a high-speed interconnection network.

The NCHC is also responsible for the operation of the 20 Gbit/s Taiwan Advanced Research and Education Network (TWAREN), the national education and research network of Taiwan. The NCHC supports local academia and industry with hardware and software, advanced research and application development, and professional training.
The Oak Ridge Leadership Computing Facility (OLCF), formerly the National Leadership Computing Facility, is a designated user facility operated by Oak Ridge National Laboratory and the Department of Energy. It contains several supercomputers, the largest of which is an HPE OLCF-5 named Frontier, which was ranked 1st on the TOP500 list of world's fastest supercomputers as of June 2022. It is located in Oak Ridge, Tennessee.
The United States Department of Defense High Performance Computing Modernization Program (HPCMP) was initiated in 1992 in response to Congressional direction to modernize the Department of Defense (DoD) laboratories’ high performance computing capabilities. The HPCMP provides supercomputers, a national research network, high-end software tools, a secure environment, and computational science experts that together enable the Defense laboratories and test centers to conduct research, development, test and technology evaluation activities.
The IBM HPC Systems Scientific Computing User Group (ScicomP) is an international organization open to all scientific and technical users of IBM systems. At yearly meetings application scientists and staff from HPC centers present talks about, and discuss, ways to develop efficient and scalable scientific applications. These meetings provide an opportunity to give feedback to IBM that will influence the design of future systems. ScicomP is a not-for-profit group and is not affiliated with IBM Corporation.
Windows HPC Server 2008, released by Microsoft on 22 September 2008, is the successor product to Windows Compute Cluster Server 2003. Like WCCS, Windows HPC Server 2008 is designed for high-end applications that require high performance computing clusters. This version of the server software is claimed to efficiently scale to thousands of cores. It includes features unique to HPC workloads: a new high-speed NetworkDirect RDMA, highly efficient and scalable cluster management tools, a service-oriented architecture (SOA) job scheduler, an MPI library based on open-source MPICH2, and cluster interoperability through standards such as the High Performance Computing Basic Profile (HPCBP) specification produced by the Open Grid Forum (OGF).

Supercomputing in India has a history going back to the 1980s. The Government of India created an indigenous development programme as they had difficulty purchasing foreign supercomputers. As of November 2020 when ranking by number of supercomputer systems in the TOP500 list, India is ranked at number 89 in the world, with the PARAM Siddhi-AI being the fastest supercomputer in India.
Several centers for supercomputing exist across Europe, and distributed access to them is coordinated by European initiatives to facilitate high-performance computing. One such initiative, the HPC Europa project, fits within the Distributed European Infrastructure for Supercomputing Applications (DEISA), which was formed in 2002 as a consortium of eleven supercomputing centers from seven European countries. Operating within the CORDIS framework, HPC Europa aims to provide access to supercomputers across Europe.
