About

Parallel computing in Mathematica is based on launching and controlling multiple Mathematica kernel (worker) processes from within a single master Mathematica, providing a distributed-memory environment for parallel programming. Questions about starting, scheduling, waiting for and finishing processes in parallel and exchanging data between processes should use this tag.

A lot of parallelization is done autmatically (Parallelize, ParallelEvaluate, ParallelTry, ...). Many common data-handling functions also have parallel twins (ParallelMap, ParallelTable, ParallelSum, ...)

Some useful knowledge about parallel computation:

Some example questions:

If you are looking for performance optimization consider using the tag too.
