Module OpamParallelSource

Parallel execution of jobs following a directed graph

Sourcemodule type VERTEX = sig ... end
Sourcetype dependency_label = unit
Sourcemodule type G = sig ... end
Sourceexception Aborted

When one job fails due to an exception, other running jobs are interrupted and reported with this sub-exception in the Errors list

Simply parallel execution of tasks

Sourceexception Errors of int list * (int * exn) list * int list

In the simple iter, map and reduce cases, ints are the indexes of the jobs in the list. First list is return code of sucessfull commands, second those which raised expcetions, and third one those which were canceled.

Sourceval iter : jobs:int -> command:('a -> unit OpamProcess.job) -> ?dry_run:bool -> 'a list -> unit
Sourceval map : jobs:int -> command:('a -> 'b OpamProcess.job) -> ?dry_run:bool -> 'a list -> 'b list
Sourceval reduce : jobs:int -> command:('a -> 'b OpamProcess.job) -> merge:('b -> 'b -> 'b) -> nil:'b -> ?dry_run:bool -> 'a list -> 'b

More complex parallelism with dependency graphs

Sourcemodule type SIG = sig ... end
Sourcemodule Make (G : G) : SIG with module G = G and type G.V.t = G.V.t
Sourcemodule type GRAPH = sig ... end
Sourcemodule MakeGraph (V : VERTEX) : GRAPH with type V.t = V.t
