US Supercomputer Breaks Record of Being Fastest in the World With Two Quintillion Calculations per Second

A supercomputer in the US has taken the throne of being the fastest in the world. The US Department of Energy's Frontier supercomputer at Oak Ridge National Laboratory was declared to be the most powerful supercomputer officially recorded, keeping a promise made by former President Barack Obama about seven years ago. This has moved the world into a new era of computational power. The Frontier supercomputer was also declared to be the first to be capable of one quintillion operations per second. One quintillion is equivalent to a billion billions.

This new scale of operations or exascale is over a thousand times more powerful than the older scale of operations, called the pentascale.

Frontier is more than twice as fast as the previous top rank holder, Japan's Fugaku. But despite the US managing to once more reclaim its place at the top of super advanced computers, rumours remain that China had already broken the so-called exaflop barrier (calculating 1 quintillion floating point operations).

In a benchmarking test dubbed High-Performance Linpack (HPL), the result was validated. At TOP500, a twice-yearly ranking of the world's most powerful supercomputers, the standardised HPL benchmark matters the most.

“The No. 1 spot is now held by the Frontier system at Oak Ridge National Laboratory (ORNL) in the US. Based on the latest HPE Cray EX235a architecture and equipped with AMD EPYC 64C 2GHz processors, the system has 8,730,112 total cores, a power efficiency rating of 52.23 gigaflops/watt, and relies on gigabit ethernet for data transfer,” stated Top 500 group in a release.

The supercomputer “is currently being integrated and tested at the ORNL in Tennessee, USA, where it will be operated by the Department of Energy”, said Top 500.

The Frontier system was built using Advanced Micro Devices' top of the line EPYC processor chips as well as a graphics processing chip that was previously supplied to supercomputers by rival tech giant Nvidia. The system consists of 74 cabinets built by Hewlett Packard Enterprise.

In 2015, the White House announced the launch of the National Strategic Computing Initiative (NSCI), which aims to keep the United States at the forefront of high-performance computing for decades to come. The Then-President Obama had pledged to create massive exascale supercomputers within 10 years.
