[julia-users] How does Julia's @spawnat initialize variables on remote worker process?

[gultistan via julia-users]

Hi,

Below is some output; that I can't completely understand. Specifically, 
where are variables d,e,f after they are initialized? Are they created and 
destroyed dynamically on worker 2? 

julia> a,b,c
(10,20,30)

julia> whos()
Base                          Module
Core                          Module
Main                          Module
a                             Int64
ans                           (Int64,Int64,Int64)
b                             Int64
c                             Int64

julia> fetch(@spawnat 2 whos())
        From worker 2:  Base                          Module
        From worker 2:  Core                          Module
        From worker 2:  Main                          Module

julia> fetch(@spawnat 2 d,e,f = (a,b,c))
(10,20,30)

julia> fetch(@spawnat 2 whos())
        From worker 2:  Base                          Module
        From worker 2:  Core                          Module
        From worker 2:  Main                          Module

julia> whos()

c                             Int64
