Fast Audio Thread Synchronization for GPU Data

Explore advanced techniques for fast audio thread synchronization with GPU data in this conference talk from the Audio Developer Conference 2023. Delve into solutions developed for a GPU-based physics simulation instrument, focusing on synchronizing large data models between GUI and audio threads. Learn about wait-free approaches, SPSC queues, and custom data structures that avoid mutexes and memory allocations. Discover strategies for running GPU physics simulations at audio sample rates, addressing memory bandwidth issues, kernel execution latency, and cross-GPU-thread synchronization. Gain insights into OpenCL language limitations and optimizations for reliable GUI and audio thread synchronization in compute-intensive physics simulations. Prerequisite knowledge of C++ programming and thread synchronization primitives is recommended.
