package parany
val run :
?preserve:bool ->
?core_pin:bool ->
?csize:int ->
int ->
demux:(unit -> 'a) ->
work:('a -> 'b) ->
mux:('b -> unit) ->
unitrun ~csize:10 16 ~demux:f ~work:g ~mux:h will run in parallel on 16 cores the g function. Inputs to function g are produced by function f and grouped by 10 (the chunk size csize). If not provided, csize defaults to one. The performance-optimal csize depends on your computer, the functions you are using and the granularity of your computation. Elements which are fast to process may benefit from a csize greater than one. The demux function f must throw Parany.End_of_input once it is done. Outputs of function g are consumed by function h. Functions f and g are run by different unix processes. Function g is run by several processes at the same time (16 in this example). Only function mux is run by the same process that called Parany.run. ~core_pin is an optional parameter which defaults to false. Core pinning can improve performance but should not be used on computers with many users or running several parany computations at the same time. ~preserve is an optional parameter which defaults to false. If set to true, results will be accumulated by h in the same order that function f emitted them. However, for parallel performance reasons, the jobs are still potentially computed by g out of order.
