It does this by constructing a RemoteRef on each worker process and then using put!   to put the data onto each process.  These RemoteRef's are stored in an array.  The main function then calls some other functions on the worker processes  using the data in the RemoeRefs  and then returns the result, which was collected on the main process.  I can post the code if it would be helpful.      What I have observed is, that over successive calls to this main function, the total amount of memory used by each one of the worker processes grows.    Is there a way to avoid this?  I have tried using take!  , but it just increased the total memory allocated  measured using  time .    Thank you very much for your help and I am sorry if this is a really easy question whose answer is in the User Manual  I've read it several times today, and I can't find anything .    - Gregory Plumb     Isaiah    3 31 15   Not sure if this applies to your case, but there are some known issues with memory management of parallel constructs. See e.g. https:  github.com JuliaLang julia issues 8912 and others linked from there.      Ben Arthur    3 31 15   also https:  github.com JuliaLang julia issues 6567
