About this site

An interactive history of scientific supercomputing — from hand-cranked differential analyzers to exascale machines training AI models of protein structure and climate. The site is a set of independent pages: a chronological timeline, several genealogies (machines, companies, people, languages), and a few institutional deep-dives (NSF centers, national labs). What each page covers and where the information came from is below.

What each page is

The main machine family tree: an SVG genealogy spanning 11 lineages — US mainframes and supercomputers, UK machines, China, Japan, India, Sweden, and the Soviet Union and special-purpose machines (Anton, Elbrus) — from the 1940s IAS machine to 2024's El Capitan.
A genealogy of scientific codes and numerical methods across nine domains: nuclear physics/Monte Carlo, weather/climate, fluid dynamics, molecular dynamics, quantum chemistry/DFT, N-body/cosmology, radio astronomy, genomics/biology/AI, and cryptography — from 1931's differential analyzer to 2022's post-quantum cryptography standards.
The five original NSF supercomputer centers (NCSA, SDSC, PSC, CTC, JvNC) — who founded them, where, and the sequence of machines each one operated from the mid-1980s to today.
US national laboratory supercomputing programs — ORNL, LLNL, ANL, LANL, SNL, NERSC, plus NCAR and NSA — and the flagship machines each has run since the 1960s–90s through the current exascale era.
An industrial genealogy of HPC vendors: IBM, Remington Rand/UNIVAC, CDC, Cray, Thinking Machines, Intel, NEC, Fujitsu, NVIDIA, and HPE, plus a wave of 1980s–90s "mini-supercomputer" and MPP challengers (Convex, Alliant, Kendall Square Research, MasPar, nCUBE, Meiko) that didn't survive but shaped the architectures that did.
A genealogy of the people behind supercomputing, split into the engineers who built the machines and the scientists who invented the methods — architects, programmers, and domain specialists across nuclear/Monte Carlo, climate, CFD, DFT, molecular dynamics, cosmology, and genomics.
A genealogy of programming languages relevant to scientific computing — assembly and systems languages, Fortran and its scientific-computing descendants, structured/object-oriented languages, scripting languages, functional languages, and declarative/symbolic languages.
A genealogy of minicomputers and workstations — the machines that sat between mainframes and personal computers and brought interactive, departmental-scale computing to labs and universities.
A genealogy of personal computers across eight lineages — Altair/CP/M, Apple, Commodore, IBM PC/Wintel, Atari, NeXT/BeOS, Acorn/ARM, and Tandy/RadioShack — from the 1975 Altair 8800 to the 2020 MacBook Air M1.
A photographic gallery of supercomputers from ENIAC to Frontier, with specs, location, and significance for each. Images are pulled live from Wikipedia.
A flat, chronological list of named computational breakthroughs — algorithms, codes, and results — across the same domains as Research, each with the machine it ran on and why it mattered.
Photo-gallery companion to Minis & WS, with specs and significance for each machine.
Photo-gallery companion to PCs, with specs and significance for each machine.

Sources

This site was put together by an AI assistant (Claude) from publicly available reference material, not from original archival research. Treat it as a popular, educational overview rather than a citation-grade history — the per-machine Wikipedia links and per-milestone paper links on each page are the best starting point if you want to verify or dig deeper into any specific claim.

  • Wikipedia — the primary reference for individual machines, people, algorithms, and companies. Most nodes across the genealogy pages link directly to their Wikipedia article; the Machines, Mini Gallery, and PC Gallery pages pull thumbnail images live from the Wikipedia REST API.
  • Peer-reviewed papers — the Timeline and Research pages link to original papers (with DOIs where available) for landmark results, e.g. Springel et al. on the Millennium Simulation, Jumper et al. on AlphaFold2.
  • Top500.org — supercomputer rankings and performance figures (Top500, HPCG, HPL-AI, Graph500) referenced throughout the Machines, Companies, NSF Centers, and Labs pages.
  • Official institutional sources — national laboratory (ORNL, LLNL, ANL, LANL, SNL), NSF center, and NERSC/NCAR websites and public fact sheets for machine specs, deployment dates, and program history.
  • Vendor documentation and press materials — Cray, IBM, HPE, Intel, NVIDIA, Fujitsu, and NEC technical specifications and announcements for hardware details.
  • General domain knowledge — the model's own training-derived knowledge of computing and scientific history, used to fill in narrative context, significance, and connections between entries, then cross-checked against the sources above where possible.
