Abstract: A wall block includes a first end portion, a second end portion, and an intermediate portion extending between the interconnecting the first and second end portions. The first end portion includes a first face and first and second opposing side surfaces. The second end portion includes a second face and third and fourth opposing side surfaces. The first and second side surfaces taper toward each other extending in a direction from the first face toward the second face. The third and fourth side surfaces taper toward each other extending in a direction from the second face toward the first face.

Abstract: A wall block comprising first and second opposing, parallel side walls extending lengthwise and first and second opposing, parallel end walls extending between respective ends of the side walls is disclosed. The first and second side walls are longer than the first and second end walls. At least first and second trapezoidal shaped projections extend outwardly from the first side wall, where the first and second projections are configured to be received in slots of adjacent blocks in a wall. A block assembly comprising a trunk block and a face block is also disclosed, where at least one trapezoidal shaped slot is configured to receive a trapezoidal shaped projection of the trunk block. A wall comprising at least a first course comprising a plurality of face blocks and a plurality of trunk blocks is further disclosed.

Abstract: A cache manager monitors storage capacity levels of a cache node storing data as cache entries. Upon determining a storage capacity threshold is reached, the cache manager begins evicting cache entries. In evicting the cache entries, the cache manager identifies a reduction level, and configures one or more time steps. The cache manager evicts cache entries within the one or more time steps until the reduction level is achieved.
