Being more explicit about the data movement is generally my preference as well, but it sounds like you might be able to get away with the `CachingPool` here.

Something like this might work for you:

```julia
foo(k) = bar(nm, k) # capture nm in a closure
pool = CachingPool(workers())
@sync for worker in workers()
    @async while length(queue) > 0
        idx = pop!(queue)
        results[idx] = remotecall_fetch(foo, pool, ks[idx])
    end
end

```
