  "message": "[CPU] Block root op chain fusion in non-root anchored tiling. (#24098)\n\nWhen tiling from a non-root anchor op at VectorInnerParallelTiles level,\nthere are two paths, because the intention is for tiling dimensions that\nnot captured by rootOp:\n(a) Start from an anchor op before the root op.\n(b) Start from an anchor op after the root op.\n\nIn both cases, we should not fuse rootOp and the consumers/producers for\n(a)/(b).\n\nThe revision aims to fix the case that reduction dimension is not tiled\non the root op which fused the root op unintended; it results in numeric\nissues as expected. This can happen when the reduction dimension is much\nless than native vector sizes.\n\nSigned-off-by: hanhanW \u003chanhan0912@gmail.com\u003e",
