Hello
I am a beginner in Julia and have been trying to build an application in
it. Although, I am facing a conceptual doubt.
I am working with 4 worker processes on one node.
> addprocs(4)
I define a variable 'a' on all the processes.
julia> @everywhere a=4
Next, I try to modify the value of 'a' at worker#2
julia> @spawnat 2 a=5
RemoteRef(2,1,16)
julia> fetch(ans)
5
Now, if I print the value of 'a' at all processors, I get :
julia> @everywhere println(a)
4
From worker 2: 4
From worker 4: 4
From worker 5: 4
From worker 3: 4
Why is the modified value of 'a' not reflected here ? Am I missing
something in the logic ?
Thanks so much!
