Amdahl's Law
Concept**Amdahl's Law** describes a fundamental limit on performance improvement in parallel or optimized systems: “the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used.”[3882ee73-d7fa-4f61-9805-76c7e17a2ebd] In practice, this means that accelerating only the parallelizable or optimized portion of a workload cannot eliminate time spent in sequential, synchronization, scheduling, or other non-optimized parts of the system.
