摘要： Systems and methods for dynamically remapping elements of a set to another set based on random keys. Application of said systems and methods to dynamically mapping regions of memory space of non-volatile memory, e.g., phase-change memory, can provide a wear-leveling technique. The wear leveling technique can be effective under normal execution of typical applications, and in worst-case scenarios including the presence of malicious exploits and/or compromised operating systems, wherein constantly migrating the physical location of data inside the PCM avoids information leakage and increases security; wherein random relocation of data results in the distribution of memory requests across the physical memory space increases durability; and wherein such wear leveling schemes can be implemented to provide fine-grained wear leveling without overly-burdensome hardware overhead e.g., a look-up table.

摘要： A collective communication apparatus and method for parallel computing systems. For example, one embodiment of an apparatus comprises a plurality of processor elements (PEs); collective interconnect logic to dynamically form a virtual collective interconnect (VCI) between the PEs at runtime without global communication among all of the PEs, the VCI defining a logical topology between the PEs in which each PE is directly communicatively coupled to a only a subset of the remaining PEs; and execution logic to execute collective operations across the PEs, wherein one or more of the PEs receive first results from a first portion of the subset of the remaining PEs, perform a portion of the collective operations, and provide second results to a second portion of the subset of the remaining PEs.
