Data Partitioning for Multiprocessors with Memory Heterogeneity and Memory Constraints

[摘要] The paper presents a performance model that can be used to optimally distribute computations over heterogeneous computers. This model is application-centric representing the speed of each computer by a function of the problem size. This way it takes into account the processor heterogeneity, the heterogeneity of memory structure, and the memory limitations at each level of memory hierarchy. A problem of optimal partitioning of ann-element set overpheterogeneous processors using this performance model is formulated, and its efficient solution of the complexity O(p3× log2n) is given.
