Free stale GPU residency entries and optionally flush the model cache

Scans the residency registry and removes entries whose backend no longer reports the associated device buffer as present. Such stale entries arise when a backend is unloaded or the device is reset between sessions. Optionally flushes all cached matrix factors (QR, Cholesky, SVD) from the session model cache.

Usage

amatrix_gc(cache = FALSE)

Arguments

cache

Logical. If TRUE, also remove all model-cache entries. Default FALSE.

Value

Invisibly, a list with two integer elements:

dead_entries

Number of stale residency slots removed.

cache_entries_cleared

Number of model-cache entries flushed (0 when cache = FALSE).
