How fast was the first Cray supercomputer?

TECH STORY: The Cray Y-MP was the world’s first supercomputer to sustain over 1 gigaflops. Considered a follow-on to the X-MP, the initial system had eight parallel vector processors, denser circuits, and a larger central memory. The Y-MP reached a peak speed of 2.67 gigaflops.

What happened Cray Computer?

Seymour Cray later formed Cray Computer Corporation (CCC) in 1989, which went bankrupt in 1995. Cray Research was acquired by Silicon Graphics (SGI) in 1996. business from SGI and adopted the name of its acquisition. The company was acquired by Hewlett Packard Enterprise in 2019 for $1.3 billion.

Who invented CDC 6600?

Seymour Cray

How does a Cray 1 compare to a modern supercomputer?

If you mean how does a Cray 1 (the 1975 computer) compare to a modern supercomputer – The Cray 1 had a ‘peak FLOPS’ (i.e. the number of floating point operations it could theoretically perform in a second) of 160 Million Flops*. Summit, the IBM-built supercomputer on the top of the current list has a peak of about 200,000 trillion flops.

How much power does a supercomputer use?

The efficiency of supercomputers continued to increase, but not dramatically so. The Cray C90 used 500 kilowatts of power in 1991, while by 2003 the ASCI Q used 3,000 kW while being 2,000 times faster, increasing the performance per watt 300 fold.

What is the most successful supercomputer in history?

Four years after leaving CDC, Cray delivered the 80 MHz Cray-1 in 1976, and it became the most successful supercomputer in history.

How many flops does a computer have?

Summit, the IBM-built supercomputer on the top of the current list has a peak of about 200,000 trillion flops. So, a modern top-of-the line computer is theoretically about 1 billion times faster. However, that isn’t quite the whole story.
