I've explained in more detail in a StackOverflow post but essentially what I'm trying to do is have an integer variable that several processes can access and, if one returns an integer smaller than that variable, can update. The general approach is something like this:  x   Channel Int64  1  put! x,n    everywhere function f item,chan      going   true     count   0     while going          going   false           perform some operations         if  count   fetch chan  && !conditions_met                  conditions_met checks the other termination conditions             going   true             count +  1         end     end      count +  1      if  count   fetch chan           take! chan          put! chan,count      end      return count end  y    parallel  min  for i in collection     f i,x  end  Am I correct in my logic? Is this something I should be able to do?     michael    Mar 10   At the suggestion of  axsk I tried this again but using a SharedArray instead of a channel and it seems to be working now. I am curious as to why my approach didn't work, if anyone cares to explain.   I'm on v0.4.3       michael    Mar 11   Going off of an answer on StackOverflow using RemoteRef instead of Channel works as well. The answerer points out the reason why the latter doesn't work.
