[julia-users] parallel loop with mutable types

[Jon Norberg]

I have: 

type parms
  r::Float64
  K::Float64
end

k=Array(parms,20)

for i =1:20 k[i]=parms(1.1,2.2) end

addprocs(1)

nprocs() -> 2

@parallel for i=1:20 k[i].r=2.0 end

gives error:

julia> @parallel for i=1:20 k[i].r=2.0 end
fatal error on 2:
julia> ERROR: parms not defined

Do I need to share the k array or somehow let the parallel code know how to 
handle an array of type parms?

Thanks for any help here!
