Is it possible to set up Julia for distributed computing in Windows cluster? How?  Is there a way to delete a variable once created? Not just free mem making x 0.   Thank you.  M.     Tony Kelman    8 12 15   Good question. I have not tried to do this, it's been about 6 years since I last used a Windows cluster.  Built-in, it looks like the only remote cluster manager available by default in base Julia communicates over ssh - http:  docs.julialang.org en latest manual parallel-computing  man-clustermanagers  Is your cluster using Windows HPC Server? How would you usually create parallel jobs and communicate between workers? Are you using Microsoft MPI? There is an open pull request for adding support for Microsoft MPI to MPI-jl  see https:  github.com JuliaParallel MPI-jl issues 51 and https:  github.com JuliaParallel MPI-jl pull 52 , but I don't think it's actually been tested across multiple machines yet. Maybe support for Windows HPC Server could be added to the ClusterManagers-jl package? Would have to check the documentation both for ClusterManagers-jl https:  github.com JuliaParallel ClusterManagers-jl and Windows HPC Server https:  technet.microsoft.com en-us library ff919397.aspx to see what would be needed.  I don't think there's an easy way to delete a variable binding. You can call workspace   which really just moves the current content of your Main module to Main.LastMain.      Marcio Sales    8 13 15   Hi Tony,  Thanks for your answer. To be honest, at first I was thinking about a simple way to connect 2 or 3 computers and run julia scripts in parallel, but great if someone brings a buildin solution to the grid problem.  There's this putty open source server, but I read somewhere that even that would require changing the ClusterManagers-jl. Has anyone tried that with any success?  M.      Sisyphuss    8 13 15   Is `x nothing` a good idea, since `nothing` has no meaning and could be tested `x  nothing`?      Marcio Sales    8 13 15  Translate message to English    x would still be listed.      Sisyphuss    8 13 15   Yes. It has the same effect as `x 0`. It just give a safer value to `x`.      Marcio Sales    8 13 15   Makes sense. Thanks.
