AllocationRecorder

Qualified name: algan.utils.memory\_utils.AllocationRecorder

class AllocationRecorder

Bases: object

Captures every ManualMemory allocation into a scope tree.

get_tensor is the arena’s single allocation entry point, so recording there covers every current and future buffer with no per-site annotation. That is what lets the memory tables be regenerated by measurement rather than maintained by hand.

Methods

clear	Drop scopes left open by an aborted render.
note_alloc
note_temp
pop_scope
push_scope
scopes	Every recorded scope with name, outermost first.

Attributes

current

clear()

Drop scopes left open by an aborted render.

ManualMemory.reset runs while an OOM is still unwinding, so any open scope holds a truncated event stream that stops at the failing allocation. Detaching those keeps a partial measurement from being mistaken for a complete one – which would bias a calibrated coefficient downwards, the one direction that causes OOMs. They stay on abandoned for diagnostics.
