Concurrent Processing. The easy …Parallel Computing. Julia supports these four categories of concurrent and parallel programming: Julia Tasks allow suspending and resuming computations for I/O, event handling, producer-consumer processes, and similar patterns. Tasks can synchronize through operations like wait and fetch, and communicate via Channel s. Parallelism is suitable for computationally intensive tasks. Concurrency can be achieved on a single processor. Parallelism often requires specialized hardware with multiple processors. Concurrency may involve less coordination. Coordinating tasks in parallel can be more complex due to the need for synchronization.
