Characteristics of Super Computer

Introduction

Typically used in research, artificial intelligence, and big data computing, a supercomputer is an incredibly durable computing system that processes data at speeds measured in floating-point operations per second (FLOPS) to conduct complex computations and simulations. Supercomputers run at their highest possible speed or their optimal computational performance rate. Processing power is the main differentiator between supercomputers and other computing devices.

Computations could be completed at 100 PFLOPS by a supercomputer. The processing speed of a typical general-purpose computer is restricted to tens of teraflops to scores of gigaflops. Supercomputers use a tremendous quantity of energy. They generate so much heat that users must keep them in cool locations.

Evolution of Supercomputers

The first two supercomputers, the IBM 7030 Stretch and Sperry Rand UNIVAC LARC were deliberately designed to be much faster than the fastest business computers on the market when they were originally released in the early 1960s. The development of supercomputing was influenced by the U.S. government's persistent sponsorship of cutting-edge, high-performing computer technology for defense applications in the late 1950s.

Supercomputers were initially produced in modest quantities for government use, but as time passed, the new technology became popular and entered the commercial and industrial sectors. For example, Control Data Corporation (CDC) and Cray Research dominated the commercial supercomputer market from the mid-1960s until the late 1970s. Considered the first commercially successful supercomputer was Seymour Cray's CDC 6600. IBM would dominate the market starting in the 1990s and continuing to the present.

Working of Supercomputers

Supercomputer architectures are made up of several central processing units (CPUs). These CPUs are arranged in memory storage and compute node clusters. Numerous nodes connected to a supercomputer can be used to address challenges in parallel processing.

The largest and most potent supercomputers comprise several parallel processors operating simultaneously. There are two approaches to parallel processing: massively parallel processing and symmetric multiprocessing. In other cases, supercomputers are scattered, which means that rather than locating all of the CPUs in one place, they draw power from numerous PCs spread over multiple locations.

While earlier systems were typically measured in IPS (instructions per second), supercomputers are measured in floating point operations per second, or FLOPS. The more effective the supercomputer is, the higher this value gets.

Supercomputers are computers with numerous CPUs, as opposed to traditional computers. These CPUs are arranged into compute nodes with a memory block and a processor or group of processors (known as symmetric multiprocessing, or SMP). Numerous nodes may be present in a supercomputer at scale. These nodes could collaborate via interconnect communications networks to find a solution to a specific problem.

Notably, data centers require cooling systems and sufficient space to house all of this equipment because of the power consumption of modern supercomputers.

Types of Supercomputers

The classes and types of supercomputers are as follows:

• Tightly connected clusters: These are collections of networked computers that work together to address a common problem. There are four methods for creating clusters to connect these computers. Four clusters are produced: massively parallel clusters, director-based clusters, multi-node clusters, and two-node clusters.
• Supercomputers with vector processors: These machines have CPUs that can handle many data items at once rather than processing each separately. This provides a form of parallelism where all array members are processed concurrently. These supercomputer processors are arranged in arrays to process several data items simultaneously.
• Special-purpose computers: These can only be used for that specific purpose and are not meant for any other usage. They are intended to deal with a particular issue. These systems focus their efforts and resources on solving the presented problem. One example of a supercomputer designed for a specific purpose is the IBM Deep Blue chess-playing machine.
• Commodity supercomputers: Standard (common) personal computers connected by quick, high-bandwidth Local Area Networks (LANs) comprise commodity supercomputers. Next, these computers collaborate to finish a single task through parallel computing.
• Virtual supercomputers: These machines operate and reside primarily on the cloud. Through the combination of numerous virtual machines on processors in a cloud data centre, it provides an incredibly efficient computing platform.

In conclusion, supercomputers demand much room due to using multiple CPUs and a massive wiring system. Additionally, the systems that are connected generate heat.
