摘要： Embodiments of erasure coded storage aggregation are disclosed. The erasure coded storage aggregation includes storing a data file as erasure coded fragments in a plurality of nodes of one or more data centers. The erasure coded storage aggregation further includes monitoring an access frequency of the data file. Based on the comparison between the access frequency and a predetermined threshold, the data file is either reconstructed from the erasure coded fragments and stored in a storage node or retained as erasure coded fragments in the plurality of nodes of the one or more data centers.

摘要： An apparatus, method and computer-readable medium provide for detecting and filtering potential race conditions. In one example, potential race conditions may be detected by determining overlap of memory accesses (e.g., read, write). Potential race conditions may be filtered as potentially benign or harmful race conditions using, for example, heuristics, comparison of output states from execution of instructions or operations in differing sequences or identifying of associated output bugs corresponding to the execution of operations in different sequences.
