Overview

Concurrency & Multi-Threading

Concurrency is about dealing with lots of things at once, but parallelism is about doing lots of things at once.

• Concurrency works on a single core that handles one or more tasks at the same time with interleaving executions
  • it's a fake parallelism, but fast enough to act like a parallelism.
• Multi-Threading starts new threads from the same process; Threads can be handled by multiple core when available
  • Still work concurrently when only single core available.
  • If number of threads exceeds number of cores, the remaining are scheduled as concurrent

What's Involved

• Task-based Asynchronous Model
  • Task Creation & Invocation
  • Task Cancellation
  • Waiting for Task
• Data Sharing & Synchronization
• Thread-safe Collections
• Task coordination
• Paralle Utilities(Paralle class & PLINQ)
