High-Performance Computing

What is High-Performance Computing?

High-performance computing (HPC) refers to the use of supercomputers and parallel processing techniques to solve complex computational problems. Unlike traditional computing, HPC systems are designed to handle tasks that require immense processing power, memory, and storage. These systems consist of interconnected nodes working together to perform billions of calculations per second, measured in FLOPS (Floating Point Operations Per Second). HPC is the foundation for solving problems in fields like climate modeling, genomics, and financial risk analysis.

Key Features of High-Performance Computing

1. Parallel Processing: HPC systems divide tasks into smaller sub-tasks that run simultaneously across multiple processors, significantly reducing computation time.
2. Scalability: HPC systems can scale horizontally (adding more nodes) or vertically (enhancing node capacity) to meet growing computational demands.
3. High-Speed Interconnects: These systems use specialized networking technologies to ensure rapid data transfer between nodes.
4. Massive Storage Capabilities: HPC systems are equipped with high-capacity storage solutions to handle large datasets efficiently.
5. Customizability: HPC architectures can be tailored to specific workloads, such as GPU-based systems for machine learning or CPU-intensive systems for simulations.
