Simultaneous Multithreading (SMT)
Simultaneous Multithreading (SMT) is a technology that allows a single processor core to execute multiple threads concurrently. By sharing the core's resources, such as execution units and caches, SMT improves overall performance and resource utilization, especially in workloads with many threads.
SMT is commonly used in modern processors, including those from Intel and AMD. It enhances the efficiency of multithreaded applications by allowing them to run more smoothly, reducing idle time and increasing throughput. This technology is particularly beneficial in environments where tasks can be parallelized, such as in data centers and high-performance computing.
