High Performance Computing (1/8) – Introduction

The term of High Performance Computing (HPC) refers to the utilization of a highly advanced computer system to perform complex and large-scale data processing in a short amount of time. The main goal of HPC is to enhance computational work and handle tasks that require high computational power and large memory. Supercomputers are examples of HPC implementation on computers specifically designed for high performance and parallel processing, such as Frontier owned by the US and Fugaku in Japan.

Here are some key aspcets related to HPC that need to be considered in the implementation process:

1. Parallel Processing
HPC often invloves parallel processing, where tasks are divided into small parts and executed simultaneously by multiple processing units. This can be done using multiple processors or even interconnected computer clusters.

2. Large Storage Capacity
HPC applications often require large and fast data storage. Therefore, HPC systems are often equipped with distributed storage or shared storage to handle large volumes of data.

3. High-Speed Communication
Efficient communication between various processing units is crucial in HPC systems. This involves the use of specialized high-speed networks to connect each computer node.

In practice, HPC is represented by supercomputer products, which are computers with extraordinary processing power and performance that, today, are owned by several countries. Supercomputer are often used to solve large-scale problems in industries that were previously unsolvable by conventional computers.

Application of HPC

Below are examples of applications that can illustrate how HPC significantly contributes to the understanding and solving of complex problems in various fields, ranging from scieentific research to technology development and problem-solving in industries.

1. Molecular Simulation in Drug Discovery
Molecular dynamics simulations involve simulating the movement of atoms and molecules over a specific time scale. In drug discovery research, HPC is essential to understand the interaction between drugs and biological targets, assisting researchers in predicting how drug molecules will interact with the highly complex structures of biological targets. This process requires highly intensive calculations and high computing power.

2. Weather Modeling for Accurate Weather Prediction
Weather modeling requires highly complex calculations to understand and forecast weather conditions. HPC is used to stimulate atmospheric and oceanographic dynamics, producing accurate short-term and long-term weather predictions. Ultimately, this can aid in disaster planning and mitigation and support various industries such as agriculture and transportation.

3. Aircraft Design Simulation and Aerodynamics Optimization
The aviation industry also utilizes HPC for numerical simulation and aircraft design optimization. Complex aerodynamic modelling can be performed to identify energy-efficient designs and minizime air resistance. This contributes to the development of more efficient and environmentally friendly aircraft.

4. Reservoir Modeling for Optimal Oil and Gas Production
HPC is employed in the oil and gas industry to simulate complex reservoirs. This modeling helps energy companies optimize oil and gas production from underground reservoirs, predict fluid behaviour, and plan drilling operations efficiently.

5. Particle Accelerator Experiments
In particle physics research, experiments in particle accelerators can be highly complex. HPC simulations assist scientists in modeling particle interactions and depicting experimental results. This is valuable for fundamental research, such as studying the basic structure of matter and natural phenomena.

6. Natural Disaster Simulation and Emergency Response
HPC simulations can be used to predict and understand the impacts of natural disasters such as earthquakes, tsunamis and storms. This is crucial for emergency response planning, evacuation, and post-disaster recovery. By modeling scenarios of various disasters, authorities can develop mitigation strategies and risk management.

7. Training Deep Learning Models
Deep learning algorithms like neural networks often require training on very large datasets in terms of quantity. This training process involves adjusting and tuning parameters numbering in the millions or even billions within the neural network architecture. HPC can accelerate the training process by performing parallel computations on many processing units.

8. Robotics and Autonomous Vehicle Simulation
In the development of robotics and autonomous vehicles, simulation is crucial for testing and training artificial intelligence algorithms. HPC can also support real-time simulations that involve complex interactions among virtual agents.

HPC on supercomputers, with all its advantages, enables us as humans to conduct simulations and process data on a large scale and complexity that is impossible to achieve with conventional computers. This opens the door to innovation, a deeper understanding of natural phenomena, and solutions to various complex problems. They can accomplish tasks that require up to millions or even billions of operations per second!
