Class Details¶

class Ufo.BaseScheduler(**kwargs)¶

Bases:: GObject.Object, Gio.Initable
Abstract:: No
Structure:: Ufo.BaseSchedulerClass

The base class scheduler is responsible of assigning command queues to filters (thus managing GPU device resources) and decide if to run a GPU or a CPU. The actual schedule planning can be overriden.

classmethod error_quark()¶

Return type:: int

abort()¶

get_resources()¶

Raises:: GLib.Error
Returns:: the currently associated Ufo.Resources object.
Return type:: Ufo.Resources

Get the current Ufo.Resources currently associated with self.

run(task_graph)¶

Parameters:: task_graph (Ufo.TaskGraph) –
Raises:: GLib.Error

set_gpu_nodes(gpu_nodes)¶

Parameters:: gpu_nodes ([Ufo.GpuNode]) – A list of Ufo.GpuNode objects.

Sets the GPU nodes that self can only use. Note, that the Ufo.GpuNode objects must be from the same #UfoArchGraph that is returned by Ufo.BaseScheduler.get_resources().

set_resources(resources)¶

Parameters:: resources (Ufo.Resources) – A Ufo.Resources object

Assigns resources to self for specific use cases.

do_abort() virtual¶

do_run(graph) virtual¶

Parameters:: graph (Ufo.TaskGraph) –
