Module type JoinMapRed.S

module type S = sig .. end

type init 

The type of data sent by server to clients at startup.

type input 

The type of input values passed to agents.

type output 

The type of overall result.

val client : JoinHelper.configuration -> unit

client cfg uses the cfg to connect to the server, and registers itself to receive computations (i.e. executions of JoinMapRed.Problem.map).

val server : JoinHelper.configuration ->
       init ->
       ('a, input) JoinPool.Simple.enum ->
       output -> output

server cfg i e z sets up a server using the passed configuration, and dispatches tasks to registered clients using a pool.

The result is reduce k1 v1 (reduce k2 v2 (... (reduce kn vn z))) where:

• reduce is a shorthand for JoinMapRed.Problem.reduce;
• the (ki, vi) couples are the values returned by the client agents (outcomes of JoinMapRed.Problem.map applications for xi), the vi being combined through JoinMapRed.Problem.combine for equal keys;
• the xi are the values successively returned by e.
