High Performance and Quantum Computing

- Overview

High-performance computing (HPC) is synonymous with the term "supercomputer," which many people may be more familiar with. A supercomputer is more than just a classic computer with high-end components, although you should certainly expect to see the highest-end components in use. 

The difference between supercomputers and ordinary computers lies in their ability to process large amounts of data and help solve complex scientific problems. They are composed of interconnected nodes and require extensive infrastructure and expertise to operate, such as facilities like Argonne National Laboratory, which uses its supercomputers to conduct groundbreaking research.

Instead, supercomputers are many powerful processors and many large memory modules interconnected into one physical, large classical computer. Imagine adding a memory module to a desktop or laptop, but on a much larger scale.

Technically speaking, HPC is not limited to purpose-built supercomputers. The term can also be applied to large groups or "clusters" of hundreds or even thousands of independent computers. 

Each server or "node" in the cluster is connected through the network to every other node in the cluster. The aggregation of processing power and memory is conceptually similar to a supercomputer, with the main difference being that the components are distributed, potentially located around the world. 

Whether using supercomputers or clusters, the goal of HPC is to solve the most complex computing tasks by using all those powerful processors and all those memories in parallel. 

Classic computers are serial in nature, dividing workloads into tasks and then executing them sequentially. HPC is essentially no different; however, it leverages its architecture to perform larger tasks and more tasks simultaneously. 

Extremely complex problems and massive cubes can then be processed a million times faster than the most powerful single server. Interestingly, the power of quantum computers is that they are inherently parallel and can essentially process all quantum information simultaneously.

Here are some examples of supercomputers:

• AI Research SuperCluster (RSC) by Meta
• Google Sycamore
• Summit by IBM
• Microsoft's cloud supercomputer for OpenAI
• Fugaku by Fujitsu
• Lonestar6 by the Texas Advanced Computing Center (TACC) at the University of Texas

- The Future of High Performance Computing

High-performance computing (HPC) utilizes supercomputers and parallel processing techniques to quickly complete time-consuming tasks or complete multiple tasks simultaneously. Technologies such as edge computing and artificial intelligence (AI) can broaden the capabilities of HPC and provide high-performance processing power for various fields.

In the age of Internet computing, billions of people use the Internet every day. Therefore, supercomputer sites and large data centers must simultaneously provide HPC services to massive Internet users. We must upgrade our data centers with fast servers, storage systems, and high-bandwidth networks. The aim is to leverage emerging new technologies to advance web-based computing and web services. 

The general computing trend is to take advantage of shared network resources and the vast amount of data on the Internet. Trends in parallel, distributed and cloud computing with clusters, MPPS (massively parallel processing), P2P (peer-to-peer) networks, grids, clouds, web services, IoT, and even quantum computing. 

Data has become a driving force for business, academic, and social progress, driving significant advances in computer processing. According to UBS, the data universe is expected to grow more than 10 times from 2020 to 2030, reaching 660 zettabytes. This is equivalent to 610 iPhones (128GB) per person. HPC presents new opportunities to address emerging challenges in these areas as organizations embrace a "data-everywhere" mentality. 

HPC is a discipline in computer science in which supercomputers are used to solve complex scientific problems. As HPC technologies have grown in computing power, other academic, government, and commercial organizations have adopted them to meet their needs for fast computing. 

Today, HPC dramatically reduces the time, hardware, and cost required to solve mathematical problems critical to core functionality. As a mature field of advanced computing, HPC is driving new discoveries in disciplines such as astrophysics, genomics, and medicine; it is also driving business value in unlikely industries such as financial services and agriculture.

- Supercomputing Technology

Supercomputing technology is a form of high-performance computing that uses multiple computers working together in parallel to solve complex problems and calculate large data sets. 

Supercomputers are made up of many components, including:  

• Interconnects
• Memory
• Processor cores
• I/O systems
• More than one central processing unit (CPU)

Supercomputing often uses high-speed interconnects and massive CPU resources. They can consist of hundreds or even thousands of nodes that work in parallel.

Supercomputers play an important and growing role in various fields of national importance. They are used to solve challenging scientific and technical problems. "Supercomputer" is an umbrella term for computing systems capable of supporting high-performance computing applications requiring large numbers of processors, shared or distributed memory, and multiple disks. 

A supercomputer is a computer with the architecture, resources, and components to enable massive computing power. Today's supercomputers consist of tens of thousands of the fastest processors capable of performing billions and trillions of calculations or calculations per second. 

Supercomputer performance is measured in floating point operations per second (FLOPS) rather than millions of instructions per second (MIPS). As of today, 500 of the fastest supercomputers in the world run Linux-based operating systems. 

Supercomputers are primarily designed for businesses and organizations that require large amounts of computing power. Supercomputers combine the architectural and operational principles of parallel and grid processing, where a process executes simultaneously on thousands of processors or is distributed among them. 

Supercomputing technology has indelibly changed the way we approach the world's complex problems, from weather forecasting and climate modeling to keeping our nation safe from cyberattacks. All the most powerful supercomputers in the world now run on Linux.

- The Current State of Quantum Computing

Quantum computing is a fundamentally different approach to computing than the type of computing we do today on laptops, workstations, and mainframes. It won't replace these devices, but by leveraging the principles of quantum physics, it will solve specific and often very complex problems of statistical nature that current computers struggle to solve. 

Currently, quantum computing is only relevant to those working in advanced computer development and research, advanced encryption, or extremely advanced high-speed networks, and those who need to process data sets that would be difficult for existing supercomputers to process. For example, if you wanted to accurately simulate the world's weather, the size of the relevant data sets would bring even the most powerful supercomputers to their knees. Quantum computers are designed to take on such tasks because of their massive and near-instantaneous multitasking capabilities.

Encryption is a major area of ​​interest, as the security industry believes that quantum computers can decrypt any existing encrypted archive almost instantly. IBM has been a leader in the development of quantum hardware, releasing quantum-resistant cryptographic algorithms in the hope of protecting data until quantum encryption is developed.

In networks, we are talking about quantum pairs that work together over infinite distances and can be used for faster-than-light communication. We are just beginning to explore the potential of this use of quantum technology, and while this could have huge implications for space exploration, the military, and transportation (remote control systems), as well as telepresence (surgery and other areas where latency may be an issue), the use There are still more than ten years to go.

Applying quantum computing to the analysis of large-scale data sets will change the nature of supercomputers. However, viable quantum computers with sufficient operating capabilities remain elusive in the future, with their feasibility expected to be decades away. However, recent changes in how we think about quantum computers will bring that date closer, as these computers better leverage existing computing technology and put quantum computing on an equal footing with other technologies.

Widespread implementation of quantum computing may still be years away. However, explore the differences between classical and quantum computing to see if the technology will become more widespread.

Quantum computers have four fundamental functions that differ from today's classical computers: (1) quantum simulation, in which quantum computers model complex molecules; (2) optimization (i.e., solving multivariate problems at unprecedented speed); (3) quantum Artificial intelligence, with better algorithms, can transform machine learning in different industries like pharma and automotive; (4) Prime factorization, which can revolutionize encryption. 

There are four types of quantum computers currently under development that use: 

• light particles
• trapped ions
• superconducting qubit
• Nitrogen vacancy centers in diamonds

Quantum computers will enable many useful applications, such as being able to simulate many changes in chemical reactions to discover new drugs; developing new imaging techniques for healthcare to better detect problems in the body; or speeding up our design of batteries, new materials and flexibility The speed of electronics."

- The Way Forward: Bringing HPC and Quantum Computing Together

Classical computing has been the norm for decades, but in recent years, quantum computing has continued to advance rapidly. The technology is still in its early stages, but has existing and many more potential uses in artificial intelligence/machine learning, cybersecurity, modeling and other applications. Widespread implementation of quantum computing may still be years away.

When approaching the design, development and integration of quantum computing solutions, it is important to keep in mind that for the foreseeable future, quantum computers will act as computing accelerators requiring substantial classical computing support. 

Whether using supercomputers or clusters, the goal of HPC is to solve the most complex computing tasks by using all those powerful processors and all those memories in parallel. Classic computers are serial in nature, dividing workloads into tasks and then executing them sequentially. 

HPC is essentially no different; however, it leverages its architecture to perform larger tasks and more tasks simultaneously. Extremely complex problems and massive cubes can then be processed a million times faster than the most powerful single server. 

Interestingly, the power of quantum computers is that they are inherently parallel and can essentially process all quantum information simultaneously. 

HPC resources, such as quantum computers, can be accessed via the cloud. However, the Internet can cause latency issues. In other words, data transfer becomes a bottleneck, slowing down calculations. 

This bottleneck can occur if HPC and quantum computing resources are connected through a network. So part of the drive to integrate quantum computers into HPC centers is to eliminate this latency and facilitate the fastest possible data transfer.

The ultimate goal of a self-contained quantum computer is a laudable goal, but it's still far in the future. For now, the goal should be seamless interaction between quantum computers and existing HPC infrastructure.

To maximize the chance of a successful collaboration, it is best for the quantum computer to be on premises. That is, the quantum computer should be located at the HPC center.
