What are the challenges of exascale computing?
Perhaps the most significant challenge for exascale computing is bounding the energy required for computation. DOE/NNSA has set a power budget for an exascale platform at roughly 20 megawatts. This is a typical power load for a modern large data center.
Why do we need exascale computing?
Exascale computers provide unprecedented processing power and memory so that researchers can perform very large-scale simulations. The ECP is also investing in 24 application areas that are critical to the DOE mission in basic sciences, applied energy and national security.
How does exascale computing works?
Exascale computing refers to computing systems capable of at least one exaflop or a billion billion calculations per second (1018). That is 50 times faster than the most powerful supercomputers being used today and represents a thousand-fold increase over the first petascale computer that came into operation in 2008.
What is a petaflop equal to?
What is a petaFLOPS? One petaFLOPS is equal to 1,000,000,000,000,000 (one quadrillion) FLOPS, or one thousand teraFLOPS. 2008 marked the first year a supercomputer was able to break what was called “the petaFLOPS barrier.” The IBM Roadrunner shocked the world with an astounding Rpeak of 1.105 petaFLOPS.
What is the most powerful supercomputer in the world?
Fugaku
Since June 2020, the Japanese Fugaku is the world’s most powerful supercomputer, reaching initially 415.53 petaFLOPS and 442.01 petaFlops after an update in November 2020 on the LINPACK benchmarks. China currently dominates the list with 188 supercomputers, leading the second place (United States).
What’s faster than a petaflop?
A gigaflop is a billion floating-point operations per second, a teraflop is one trillion, and a petaflop is a quadrillion. FLOPS particularly matter when you are talking about high-performance computing.
