The history of supercomputers

Cdc-6600-Supercomputer

The history of supercomputers a slideshow @ ExtremeTech.

Have you ever wondered why a supercomputer is called a supercomputer? Is it the number of processors or the amount of RAM? Must a supercomputer occupy a certain amount of space, or consume a specific amount of power?
The first supercomputer, the Control Data Corporation (CDC) 6600, only had a single CPU. Released in 1964, the CDC 6600 was actually fairly small — about the size of four filing cabinets. It cost $8 million — around $60 million in today’s money — and operated at up to 40MHz, squeezing out a peak performance of 3 million floating point operations per second (flops).


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. My first assembly language class was at SMU Engineering School (a summer-semester class, before I’d even started my freshman year) and they had a CDC6600. It was a SWEET machine. Sure, it was a bit elderly by the summer of 1975, but it was easy to program and that 60-bit word was handy.

    They also had a room where you could get assistance in debugging, JCL, etc., (what we now would call a… ‘Helpdesk’), which was named: “House of Ill-Compute”.

    We had the same machine at SUNYAB. Compute times were way-fast, but the turnaround time from submitting the card deck to getting your listing was upwards of 20 minutes. I’d often run the same calculation on my TI-59 and get the answer sooner.

    We had a CDC Cyber 173 (same basic architecture) at SUNYAB. Compute times were way-fast, but the turnaround from submitting the card-deck to getting your listing was often more than 20 minutes. I’d sometimes program the same algorithm into my TI-59 and let it chew on it while waiting. The TI usually won.
