A method is provided to progressively load and further process data in a hierarchical lock-free structure. The method includes generally four steps: (a) defining the hierarchical lock-free structure, (b) loading the data into the hierarchical lock-free structure; (c) processing the loaded data, and (d) repeating steps (b) and (c) such that progressively more data are loaded and become available for processing. The hierarchical lock-free structure includes a first level of data including data segments, wherein each of the data segments forms a second level of data. The structure is such that each of the data segments in the second level of data becomes available for further processing when the data segment is referenced in the first level of data. Thus, during the loading step (b), a reference is set in the first level of data to each of the data segments in the second level of data as the data segment is loaded. Then, the processing step (c) process each of the data segments in the second level of data to which a reference is set in the first level of data.
