Explore multi-threading in Julia with PARTR in this 26-minute conference talk from JuliaCon 2019. Dive into the evolution of threading in Julia, covering past implementations, current features, and future developments. Learn through practical examples including parallel merge sort, Prime Sieve of Eratosthenes, and prefix scan, with performance comparisons between parallel and single-threaded implementations. Gain insights into PARTR's relationship with threading, scheduling dynamics, thread spawning limits, and alternative threading models. Address key questions about distributed computing, low-level details, composition with pmap, scheduler priorities, and BLAS native threads. Enhance your understanding of Julia's multi-threading capabilities and their practical applications in high-performance computing.
