full set of cartesian indices to do their lookup (see [`IndexStyle`](@ref) to
introspect which is which).

When iterating over all the indices for an array, it is
better to iterate over [`eachindex(A)`](@ref) instead of `1:length(A)`.

Module [`Distributed`](@ref man-distributed) must be explicitly loaded on the master process before invoking [`addprocs`](@ref).
It is automatically made available on the worker processes.

Note that workers do not run a `~/.julia/config/startup.jl` startup script, nor do they synchronize
their global state (such as global variables, new method definitions, and loaded modules) with any
of the other running processes. You may use `addprocs(exeflags="--project")` to initialize a worker with
a particular environment, and then `@everywhere using <modulename>` or `@everywhere include("file.jl")`.

Other types of clusters can be supported by writing your own custom `ClusterManager`, as described
below in the [ClusterManagers](@ref) section.
