Device (arrayjit.Arrayjit.Backend

Parameters

module Device_types : Backend_intf.Device_types

module Alloc_buffer : 
  Backend_intf.Alloc_buffer
    with type buffer_ptr := Device_types.buffer_ptr
     and type stream := Device_types.stream

Signature

include module type of struct include Device_types end

include Backend_intf.Device_config

include Backend_intf.Buffer

type buffer_ptr = Device_types.buffer_ptr

include sig ... end

type dev = Device_types.dev

Interface to a device driver.

val sexp_of_dev : dev -> Sexplib0.Sexp.t

type runner = Device_types.runner

Interface to a stream driver.

val sexp_of_runner : runner -> Sexplib0.Sexp.t

type event = Device_types.event

An event tracks if a stream finished computing past a particular point in its schedue. These values are used internally for scheduling across streams of the backend, and can be used for explicit scheduling.
