triton.experimental.gluon.language.amd.rdna4.CachePolicy

class triton.experimental.gluon.language.amd.rdna4.CachePolicy(self, temporal: str = 'regular')

Cache hints for gfx12 (RDNA4 and CDNA5) memory accesses, taken by the buffer ops and, on CDNA5, the async_copy and tdm ops.

The hints are performance-only and never affect coherence. The coherence scope of an access comes from the op’s scope= argument instead.

Parameters:

temporal (str) – How long the data is expected to stay in the caches (TH): "regular", "none" (not expected to be reused), "high" (expected to be reused) or, for loads only, "last_use" (the last read of the data, which the caches can drop). "last_use" can’t be combined with the "sys" scope.

__init__(self, temporal: str = 'regular') → None
