Remote Code Load
From Erlang Community
[edit] Problem
Remote Load New Code to All Nodes
[edit] Solution
Solution attribution: this example is buried in erlang rpc multicall doc.
%% Find object code for module Mod
{Mod, Bin, File} = code:get_object_code(Mod),
%% and load it on all connected nodes including this one;
%% the next time the code is called it will be using the new version
{Replies, _} = rpc:multicall(code, load_binary, [Mod, Bin, File,]),
%% if this node were the "master/admin" node
%% then to push to everything but this node use:
%% {Replies, _} = rpc:multicall(nodes(), code, load_binary, [Mod, Bin, File,]),
%% and then maybe check the Replies list.

[edit] Discussion
This sort of change is tedious within other network infrastructures. see erlang.org rpc multicall doc for further details.
