[julia-users] The simple @parallel example from the docs not working

[Marius Millea]

Kinda new to Julia so not sure where to post this but I'll start here. The 
simple example from the docs involving @parallel and SharedArray doesn't 
seem to work. I would think I should end up with a=1:10, but instead it all 
zeros.

       @parallel for i=1:10
         a[i] = i
       end
       end

This is using a nightly build of v0.5.0 which I figured I should since this 
exact example is included in the 0.5.0 docs but not the 0.4.5 ones. In any 
case, from what I can gather this *should* also work on 0.4.5, and I've 
tried it and the results is identical as above. If I just put these 
commands in a script it also doesn't work. One note, if I just execute each 
command on its own line, rather than grouping them with the begin, then it 
works. 

Any ideas whats going on?
