# Basic Usage¶

To start using ParallelAccelerator in your own program, first import the package with using ParallelAccelerator, and then put the @acc macro before the function you want to accelerate. A trivial example is given below:

julia> using ParallelAccelerator

julia> @acc f(x) = x .+ x .* x
f (generic function with 1 method)

julia> f([1,2,3,4,5])
5-element Array{Int64,1}:
2
6
12
20
30


You can also use @acc begin ... end, and put multiple functions in the block to have all of them accelerated. The @acc macro only works for top-level definitions.
