A multiprocessor system includes a plurality of nodes (601, 690, 699) and at least one memory (680), wherein each node (601, 690, 699) includes at least one processor (600, 696), a first cache (620, 692) private to the node (601, 690, 699), a second cache (640, 694) at a higher level than the first cache (620, 692), and a cache location buffer (CLB) (610) private to the node (601, 690, 699), wherein, for at least one node of the plurality of nodes(601, 690, 699), at least one of the first cache and the second cache included in the at least one node includes at least one cache location that is capable of storing a compressed data unit of varying size, the CLB included in the at least one node (601, 690, 699) is configured to store a plurality of CLB entries, each of the CLB entries including a plurality of location information values.
