I just read this thread from @tkf who provides neat packages for Julia parallel patterns.

> Hi, thanks for your quick intro to Dagger.jl! I’ve been wanting to look into it. I think now I can see that how it is out-of-core friendly. BTW, I think it was a bit of exaggeration when I said “scheduler”. It was just a mechanism to hook different implementation of reduce (sequential, threaded, distributed, unordered variant of them, etc.) into the for loop syntax. So it’s not a scheduler in the sense of e.g., partr. Just as a fair warning(?), I don’t think halve is tested outside of my pack…
