The Scheduler Saga

Explore the inner workings of the Go scheduler in this 31-minute conference talk from GopherCon 2018. Delve into the M:N multiplexing of goroutines on system threads, examining mechanisms for scheduling, unscheduling, and rebalancing goroutines. Learn how the scheduler supports the netpoller and memory management systems for goroutine stack resizing and heap garbage collection. Evaluate the effectiveness and performance of the scheduler as speaker Kavya Joshi guides you through topics such as N1 scheduling, thread reuse, run queues, concurrency, work stealing, and cooperative preemption. Gain insights into the behind-the-scenes machinery that powers Go programs, efficiently runs goroutines, and coordinates network I/O and memory management.
