Excerpt
Excerpt A large-scale data processing system and method includes one or more application-independent map modules configured to read input data and to apply at least one application-specific map operation to the input data to produce intermediate data values, wherein the map operation is automatically parallelized across multiple processors in the parallel processing environment. A plurality of intermediate data structures are used to store the intermediate data values. One or more application-independent reduce modules are configured to retrieve the intermediate data values and to apply at least one application-specific reduce operation to the intermediate data values to provide output data. |

The prior art covers distributed parallel map/reduce processing of generalized "data". The current application's "expression from a sequential program" can be seen as one example of data to be processed. Application claim 1's "compute cluster" is equivalent to prior art claim 1's "interconnected processors", and application claim 1's "execution engine" is equivalent to prior art claim 1's "master process".
