I have several servers that I'm planning to use to run some simulations in Julia. The problem is, I can only add remote processes to a single server. If i try to add the processes to the next server I get an error. This is what I'm trying to do and what I get
addprocs(["user@host1"], tunnel=true, dir="~/julia-483dbf5279/bin/", sshflags=`-p 6969`) addprocs(["user@host2"], tunnel=true, dir="~/julia-483dbf5279/bin/", sshflags=`-p 6969`) id: cannot find name for group ID 350 Error [connect: host is unreachable (EHOSTUNREACH)] on 3 while connecting to peer 2. Exiting. Worker 3 terminated. ERROR (unhandled task failure): EOFError: read end of file in read at stream.jl:810 in message_handler_loop at multi.jl:844 in process_tcp_streams at multi.jl:833 in anonymous at task.jl:67 The host is reachable and I can connect to it via ssh. I found on Github [1] that the processes on different nodes need to be able to communicate without ssh tunneling. All my serves are behind a firewall, so this is not possible. Is there any alternative for adding multiple processes to different servers? I'm using the latest nightly build of Julia, which is on version 4.0. https://github.com/JuliaLang/julia/issues/6256
