The Wolfram Language automatically sets up the infrastructure for parallel computing on standard systems, and provides a variety of tools for sharing and synchronizing definitions across all kernels participating in a parallel computation.

Broadcasting Computations & Definitions

ParallelEvaluate —evaluate an expression on all parallel subkernels

DistributeDefinitions — distribute definitions to all parallel subkernels

ParallelNeeds — load the same package into all parallel subkernels

ClearDistributedDefinitions — clears previously distributed definitions

Continuously Shared Variables & Functions »

SetSharedVariable — set symbols to share values across subkernels

SetSharedFunction — set functions to share downvalues across subkernels

UnsetShared — stop sharing variables or functions

$SharedVariables  ▪  $SharedFunctions

Low-Level Kernel Setup

LaunchKernels — launch subkernels

AbortKernels — abort running computations on all subkernels

CloseKernels — close down subkernels

$KernelCount — number of currently running parallel subkernels

ParallelKernels — list of currently running parallel subkernels

$KernelID — unique ID for each parallel subkernel

$DefaultParallelKernels — default list of kernels to launch
