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.

- The Future of Quantum Computing

Quantum technologies offer game-changing opportunities across materials, food and climate change – and are seeing significant developments and increases in funding every year. What actions can businesses, governments and experts take to prepare to maximize the positive potential of this new form of computing and communication? 

Quantum computing is a multidisciplinary field that includes aspects of computer science, physics and mathematics, using quantum mechanics to solve complex problems faster than classical computers. 

The field of quantum computing includes hardware research and application development. By exploiting quantum mechanical effects such as superposition and quantum interference, quantum computers can solve certain types of problems faster than classical computers. 

Some applications where quantum computers could provide this speed boost include machine learning (ML), optimization and simulation of physical systems. The ultimate use case could be portfolio optimization in finance or simulation of chemical systems, solving problems that are currently beyond the reach of the most powerful supercomputers on the market.

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 Current State of Quantum Computing

Quantum computing uses specialized technology - including computer hardware and algorithms that take advantage of quantum mechanics - to solve complex problems that classical computers or supercomputers can't solve, or can't solve quickly enough. 

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).

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.

- 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.
