Backends (arrayjit.Backends)

A collection of the execution backends

module Schedulers : sig ... end

val finalize : 
  'buffer_ptr 'dev 'runner 'event. (module Ir.Backend_intf.Backend
                                     with type buffer_ptr = 'buffer_ptr
                                      and type dev = 'dev
                                      and type event = 'event
                                      and type runner = 'runner) ->
  ('buffer_ptr, ('buffer_ptr, 'dev, 'runner, 'event) Ir.Backend_intf.stream)
    Ir.Backend_intf.context ->
  Base.unit

Frees the arrays that are specific to the context -- not contained in the parent context. Note: use finalize to optimize memory, it is not obligatory because all arrays are freed when their buffer_ptrs are garbage-collected.

Note: this type will get simpler with modular explicits.

val fresh_backend : 
  ?backend_name:Base.string ->
  ?config:Ir.Backend_intf.config ->
  Base.unit ->
  (module Ir.Backend_intf.Backend)

Creates a new backend corresponding to backend_name, or if omitted, selected via the global backend setting. It should be safe to reinitialize the tensor system before fresh_backend.
