The logic that controls synchronization of data between nodes should be implemented on the application level. - ``NumericTable`` does not accumulate information about data coming in streaming way. All necessary computations are done on the level of the |product| algorithm and/or application software. The library supports the following data layouts: - Heterogeneous, Array Of Structures (AOS) - Heterogeneous, Structure Of Arrays (SOA) - Homogeneous, dense - Homogeneous matrix, dense - Homogeneous symmetric matrix, packed - Homogeneous triangular matrix, packed - Homogeneous, sparse CSR The optimal data layout for homogeneous and heterogeneous numeric tables highly depends on a particular algorithm. You can find algorithm-specific guidance in the Performance Considerations section for the appropriate algorithm.
