Nebenläufigkeitskontrolle
Nebenläufigkeit refers to the ability of a system to handle multiple tasks or computations in a way that their execution can overlap in time. This does not necessarily mean that tasks are executing simultaneously, but rather that their progress can interleave. A system exhibiting Nebenläufigkeit can switch between different tasks, making progress on each before moving to another, creating the illusion of concurrent execution. This is often achieved through techniques like time-sharing, where a single processor rapidly switches between different processes or threads. In contrast to parallel execution, where multiple tasks are truly running at the exact same moment on different processing units, Nebenläufigkeit focuses on managing the order and interleaving of tasks, especially in single-processor environments or when the number of tasks exceeds the available processors. This concept is fundamental to modern operating systems and concurrent programming, enabling responsive user interfaces and efficient resource utilization. It allows a computer to appear to be doing many things at once, even if it's technically only performing one operation at any given microsecond. The design and implementation of systems with Nebenläufigkeit are crucial for achieving performance and responsiveness in applications that involve multiple independent operations.
