   Rather an odd start

   Concurrency (or maybe rather parallelism (Harper)) is…

   when ’Harper’ refers to

   • Bob Harper, Parallelism is not concurrency

   The first thing to understand is parallelism has nothing to do with concurrency.

   Is this distinction standard?

   Concurrency is concerned with nondeterministic composition of programs (or their components). Parallelism is concerned with asymptotic efficiency of programs with deterministic behavior. Concurrency is all about managing the unmanageable: events arrive for reasons beyond our control, and we must respond to them.

   But then is ’concurrency’ being used this way in ’Concurrency in monoidal categories’ at The Adjoint School 2023?
