Thread Count Scaling Part 1. Introduction

Published: 10 May 2024

Tags: optimization, performance, multithreading, c++

Denis Bakhvalov introduces a case study on thread count scaling for multithreaded applications, analyzing performance across different benchmarks to understand their efficiency on multicore systems. The study reveals that most benchmarks show suboptimal scaling, highlighting the complexities of multithreading.

Some highlights:

• Benchmarks include Blender, Clang, Zstandard, CloverLeaf, and CPython, each tested with varying thread counts.

• The best-performing benchmark, Blender, achieved a 6x speedup with 16 threads, far from ideal linear scaling.

• Clang and Zstd experienced performance degradation beyond 11 threads, indicating challenges in multithreaded optimization.
