Try comparing these two function:

function serial_example()
    A = [[1.0 1.001];[1.002 1.003]
    z = A 
    for i in 1:1000000000
        z *= A
    end
    return z
end

function parallel_example()
    A = [[1.0 1.001]; [1.002 1.003]]
    z = @parallel (*) for i in 1:1000000000
        A
    end
    return z
end
