"High-performance computing (HPC) uses supercomputers and computer clusters to solve advanced computation problems."
The hardware and software components used in an HPC system, including processors, memory, interconnects, storage, operating systems, and programming models.
Parallel Computing: Parallel computing is the process of executing multiple instructions at the same time on different processors or cores to improve the speed of computation.
Distributed Computing: Distributed computing is a computing system in which a large number of computers communicate and work together to perform a specific task.
Cluster Computing: Cluster computing refers to a group of connected computers that work together as if they are a single computer.
Grid Computing: Grid computing is the use of a network of computers to perform a large, complex task.
Supercomputing: Supercomputing refers to the use of very powerful and expensive computers to perform large-scale calculations and solve complex problems.
Hardware Architecture: Hardware architecture is the design and implementation of computer hardware, including processors, memory, and I/O devices, that are optimized for high-performance computing.
Memory Hierarchies: Memory hierarchies are the different levels of memory in a computing system, ranging from CPU registers to hard disk storage.
Interconnects: Interconnects refer to the physical connections between different components of a computing system, such as processors and memory.
I/O Architecture: I/O architecture is the design and implementation of input/output devices that are optimized for high-performance computing.
Performance Metrics: Performance metrics are measures used to evaluate the performance of a HPC system, such as speed, power consumption, and scalability.
Benchmarking: Benchmarking is the process of comparing the performance of a HPC system to a set of standardized tests.
Software Architecture: Software architecture is the design and implementation of software that is optimized for high-performance computing.
Parallel Algorithms: Parallel algorithms are algorithms that are designed to run on multiple processors or cores simultaneously.
Task Parallelism: Task parallelism is the process of dividing a large task into smaller subtasks that can be executed in parallel on multiple processors.
Data Parallelism: Data parallelism is the process of dividing a large data set into smaller parts that can be processed in parallel on multiple processors.
Message Passing Interface (MPI): MPI is a standard for message passing between processors in a parallel computing system.
OpenMP: OpenMP is a standard for shared memory parallelism in a computing system.
Distributed Shared Memory (DSM): DSM is a technique for sharing memory between processors in a distributed computing system.
Heterogeneous Computing: Heterogeneous computing refers to the use of different types of processors or cores in a computing system, such as GPUs and CPUs.
Multithreading: Multithreading is the process of dividing a single task into multiple threads that can be executed in parallel on a single processor or core.
Distributed Computing: Data is distributed across multiple nodes in a network and are processed in parallel to achieve high levels of performance.
Cluster Computing: Similar to distributed computing, but with a local network of computer clusters, working together to process large amounts of data.
Grid Computing: Shares computing resources across different geographical locations to work together as a single virtual system.
Cloud Computing: A resource-sharing model that provides on-demand access to a wide range of computational resources such as CPU time, storage, and applications that are easily scalable.
Quantum Computing: Uses the principles of quantum physics to process information with exponentially higher speed and efficiency, and is ideal for optimizing complex simulations and large-scale computations.
SMP (Symmetric Multi-Processor): Refers to the use of multiple processors that share the same memory and resources to perform parallel processing.
NUMA (Non-Uniform Memory Architecture): Unlike SMP, NUMA provides each processor with its own memory, allowing processors to access data asynchronously, thereby reducing waiting times for data transfer.
MPP (Massively Parallel Processing): Is a computing architecture where multiple processors are connected together and work together to solve a common problem.
GPU (Graphics Processing Unit): Utilised for parallel processing of data, GPUs are designed to perform heavy computational workloads, delivering excellent throughput performance that CPU-based architectures cannot match.
FPGA (Field Programmable Gate Array): An architecture that uses a pre-designed array of programmable digital logic blocks that can be arranged according to the specific computation requirements obtained from the host computer.
SIMD (Single Instruction, Multiple Data): Executes the same instructions on multiple data elements, thus improving parallel performance.
MIMD (Multiple Instruction, Multiple Data): Is a parallel processing system where multiple processors can execute multiple instructions on different data sets simultaneously.
VP (Vector Processor): Uses vector instructions to operate on entire arrays or vectors of data in a single operation, and is commonly used in scientific and engineering applications.
ASIP (Application-Specific Instruction Processor): Refers to a processor that is optimised for a specific application (such as machine vision or signal processing) using specific instruction sets.
DSP (Digital Signal Processor): A specialised processor that is designed to efficiently process digital signals in real-time, making them ideal for audio, video, and image processing.
