Suppose I have a smallish number of functions that I have defined in a cell in ijulia (I'm using JuliaBox).
I'd like to be able to call the main function in parallel n times. The annoyance is that the main makes calls to the dozen or so helper functions I have defined.
Do I have to put @everywhere in front of all of these helper functions, or is there some shorter syntax that would work?
e.g. is there a command that would share all functions defined at the global level to all of the processes? Or is there a way to share a list of functions (rather than putting @everywhere in the function declaration).

A return type can be specified in the function declaration using the :: operator. This converts the return value to the specified type. This function will always return an Int8 regardless of the types of x and y .
Method Tables Every function in Julia is a generic function. A generic function is conceptually a single function, but consists of many definitions, or methods. The methods of a generic function are stored in a method table. Method tables (type MethodTable ) are associated with TypeName s.
The "splat" operator, ... , represents a sequence of arguments. ... can be used in function definitions, to indicate that the function accepts an arbitrary number of arguments. ... can also be used to apply a function to a sequence of arguments.
When I want to do this in the notebook I usually wrap the entire cell containing helper functions in @everywhere like this:
@everywhere begin
... put functions we want to share across all processes here
end
