Dynamic concurrency throttling on NUMA systems and data migration impacts

Janaina Schwarzrock et al.

Summary: Many parallel applications struggle to scale with an increasing number of threads, necessitating strategies to optimize performance and energy consumption by adjusting thread numbers. The use of Dynamic Concurrency Throttling (DCT) can introduce overheads, particularly in Non-uniform Memory Access systems, affecting data migration and overall application performance.
