Module documentation for 0.4.0
from GHC 7.10 onwards for distributed programming using lightweight
serializable closures. This package implements a serializable
closure abstraction on top of static pointers. Serializable closures
can be shipped around a computer cluster. This is useful for
implementing intuitive and modular distributed applications. See
this blog post for a hands on introduction
and this paper for the original motivation.
In GHC 8 and above, remoting a computation on another node using this library goes along the lines of
data NodeId -- Assume we're given a spaw primitive. spawn :: NodeId -> Closure (IO ()) -> IO () -- A computation to remote on another node. hello :: String -> IO () hello name = putStrLn ("Hello, " ++ name) main = do name <- getLine spawn "someAddress" (static hello `cap` name)
distributed-closure does not implement sending/receiving/spawning
closures - that’s left for higher-level frameworks. Only closure
creation, composition and (de)serialization.
