Insight into Erlang's Scheduler Functionality

The article authored by Sapan Diwakar provides an in-depth examination of how the Erlang scheduler operates to manage processes and maintain the system's resilience and high concurrency. The scheduler is described as a crucial component that uses preemptive, priority-based scheduling to give the illusion of simultaneous process execution. Erlang processes are contrasted with OS processes and threads, emphasizing Erlang's lightweight processes that have their own memory and communicate via message passing. The piece delves into the concepts of reductions, priority levels, and multi-core running, and discusses the importance of these features in the scheduling mechanism. It ends with performance optimization tips and recommendations for further reading on Erlang's scheduler.
