Comp 422: Parallel Programming

Comp 422: Parallel Programming. Lecture 8: Message Passing (MPI). Explicit Parallelism. Same thing as multithreading for shared memory. Explicit parallelism is more common with message passing. User has explicit control over processes. Good: control can be used to performance benefit.
