Type-Bound Procedures

Name	Attributes	Description
copy_cpu_gpu	pass(self)	Copy data from (maps global singleton) CPU to (maps_fnl_object) GPU.
destroy	pass(self)	Free device data owned by the helper.
initialize	pass(self)	Initialize MPI handler data.

Subroutines

copy_cpu_gpu

Copy data from the (realm-local) CPU maps to (maps_fnl_object) GPU.

subroutine copy_cpu_gpu(self, maps, verbose)

Arguments

Name	Type	Intent	Attributes	Description
self	class(maps_fnl_object)	inout		The maps.
maps	type(maps_object)	in		Realm-local CPU maps; was the maps singleton.
verbose	logical	in	optional	Flag to activate verbose mode.

Call graph

destroy

Free device data owned by the maps FNL helper.

subroutine destroy(self)

Arguments

Name	Type	Intent	Attributes	Description
self	class(maps_fnl_object)	inout		The FNL helper.

Call graph

initialize

Initialize maps from the (realm-local) CPU maps. Requires mpih_fnl (adam_fnl_mpih_global) initialized and maps populated before calling.

subroutine initialize(self, maps)

Arguments

Name	Type	Intent	Attributes	Description
self	class(maps_fnl_object)	inout		The maps, FNL backend.
maps	type(maps_object)	in		Realm-local CPU maps; was the maps singleton.
