OK, it seems a workaround may be to use something like eval(Base.Main, :(()->CPU_CORES)) in place of the standard anonymous function.
Below, Lemon.getCores(pid) doesn't work, Apple.getCores(pid) does work. Is there a better way? This workaround seems awkward and overly complicated. module Lemon export getCores getCores(pid) = remotecall_fetch(pid, ()->CPU_CORES) end module Apple export getCores getCores(pid) = remotecall_fetch(pid, eval(Base.Main, :(()->CPU_CORES))) end Still not sure whether using anonymous function,()->CPU_CORES, is a good way to return a global variable from a worker? I also noted that eval'ing in Main, Base and Base.Main all seemed to work. I'm not really sure about the differences between these modules. Can someone explain? -- Greg
