Abstract
In one embodiment, a system includes memory ports distributed into subsets identified by a subset index, where each memory port has an individual wait time based on a respective workload. The system further comprises a first address hashing unit configured to receive a read request including a virtual memory address associated with a replication factor and referring to graph data. The first address hashing unit translates the replication factor into a corresponding subset index based on the virtual memory address, and converts the virtual memory address to a hardware based memory address referring to graph data in the memory ports within a subset indicated by the corresponding subset index. The system further comprises a memory replication controller configured to direct read requests to the hardware based address to the one of the memory ports within the subset indicated by the corresponding subset index with a lowest individual wait time.
