Why is exascale computing important?
We must attain advancements in the applied sciences in order to improve decision-making and expand our understanding of the universe. Exascale computing, otherwise known as exascale supercomputing, is necessary to accelerate this understanding. Scientists and engineers can apply the data analysis powered by exascale supercomputing to push the boundaries of our current knowledge and further promote revolutionary innovations within sciences and technology.
As exascale computing becomes more prevalent around the world, there is an increasing demand for supercomputing capacities to expand and increase to maintain global leadership in science and technology sectors. With the addition of artificial intelligence (AI), machine learning (ML), and modeling and simulation, exascale computers are now exponentially more powerful than they ever have been.
Exascale computing is driving rapid advancement in the technology and science architectures of our societies. The sheer power of these machines demands responsible use—societies all over the world are experiencing dynamic shifts in their moral structures and expectations of sustainability. With exascale computing, we are beginning to discover solutions to problems that were previously believed to be impossible.
How does exascale computing work?
Exascale computing systems analyze and solve for 1,000,000,000,000,000,000 floating point operations per second (FLOPS), simulating methods and interactions of the fundamental forces within the universe.
These supercomputers are created from the ground up to handle the massive demands of today’s simulation, converged modeling, AI, and analytics workloads. Exascale supercomputers deliver reliable performance by supporting a mix of CPUs and GPUs, even from different generations, multisocket nodes, and other processing devices in a singular integrated infrastructure.
As workloads evolve rapidly, computing architecture is critical to supporting your organization’s needs. Supercomputers are buildable, with multiple silicon processing choices, and with a single management and app development infrastructure.
We need computers capable of answering the world’s most complex research questions. Exascale computers have the capacity to solve for these questions through the movement of data between processors and storage quickly, without slowdowns—despite the massive amount of hardware and components used to build them.
Exascale computing vs. quantum computing
Exascale computing is a type of ultra-powerful supercomputing, with systems performing billions of computations per second utilizing an infrastructure of CPUs and GPUs to process and analyze data. This type of compute is operated by digital systems, in conjunction with the most powerful hardware in the world.
Quantum computing does not fall under conventional compute methods, as quantum systems utilize binary codes to be active in the same moment. This process is built on allowing super-positioning and entanglement of coding to occur simultaneously, effectively analyzing and solving for problems, enabled by laws of quantum theory in physics.
Currently, exascale computing is capable of processing and solving problems, informing and delivering technological developments at a much higher rate than quantum computing. However, quantum computing is currently on a trajectory to far surpass exascale compute capacity. Quantum compute also requires much less energy consumption to power similar workloads as exascale supercomputers.
What is an exascale computer?
An exascale computer is a massive computer system stored in cabinets within warehouses or research buildings. These computers are usually owned by governments but can be owned by large conglomerates. Essentially, exascale supercomputers have such an incredibly high cost to build that scientists and researchers typically use grants to rent them.
Computer systems that are capable of exascale compute generate massive amounts of heat due to the level of processing that occurs. They must have special cooling devices within the systems and racks—or be housed in extremely cold climates—to maintain the highest level of function. They are digital computers with the highest capacity and most powerful hardware, which differentiates them from other supercomputers or quantum computers.
Exascale computers simulate fundamental laws of physics, such as granular interactions between atoms, in order to build our knowledge of the universe and everything in it. Several industries utilize this capability to better understand, predict, and build the future of the world. For example, when researchers at the National Oceanic and Atmospheric Administration (NOAA) attempt to improve their weather predictions, they examine every potential interaction of rain, wind, clouds, and other atmospheric phenomena to establish the implications of each element, down to the atomic level.
These calculations are done through basic math equations for every interaction between every single force within a given environment, in a given moment, down to the millisecond. These simple interactions quickly form trillions of combinations, calculated and analyzed by trillions of compiled math equations. Only an exascale computer can calculate at this rate. The calculations form an image or a simulation of what every interaction looks like, which can be studied to advance our understanding of the universe. Exascale supercomputers quite literally build our knowledge, helping us meet the challenges of tomorrow.
