摘要： Parallel processing of data may include a set of map processes and a set of reduce processes. Each map process may include at least one map thread. Map threads may access distinct input data blocks assigned to the map process, and may apply an application specific map operation to the input data blocks to produce key-value pairs. Each map process may include a multiblock combiner configured to apply a combining operation to values associated with common keys in the key-value pairs to produce combined values, and to output intermediate data including pairs of keys and combined values. Each reduce process may be configured to access the intermediate data output by the multiblock combiners. For each key, an application specific reduce operation may be applied to the combined values associated with the key to produce output data.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for clustering for parallel processing. One of the methods includes providing virtual machines with an interface to a shuffle service, the shuffle service executing external of the virtual machines. The method includes receiving data records through the interface, each data record having a key and a value. The method includes partitioning the data records, using the shuffle service, according to the respective keys. The method includes providing a part of the partitioned data records through the interface to the virtual machines, wherein data records having the same key are provided to the same virtual machine. Each of the virtual machines can execute on a host machine and each of the virtual machine is a hardware virtualization of a machine.
