Laskentaintensiivisyys

Laskentaintensiivisyys, or computational intensity, refers to the ratio of computational operations to data movement in a computing system. It is a crucial metric in the design and optimization of high-performance computing (HPC) systems, as it helps to identify the balance between computational power and data transfer capabilities. High computational intensity indicates that a system performs a large number of operations per unit of data transferred, which is desirable for applications that are computationally intensive, such as scientific simulations and machine learning. Conversely, low computational intensity suggests that the system spends more time moving data than performing computations, which can be a bottleneck in data-intensive applications. Optimizing computational intensity involves techniques such as improving algorithm efficiency, enhancing data locality, and leveraging advanced hardware features like vector processing units and high-bandwidth memory. By understanding and managing computational intensity, system designers can create more efficient and effective computing solutions tailored to specific workloads.
