Gpu-based method for optimizing rich metadata management and system thereof

A graphic processing unit (GPU)-based method for optimizing rich metadata management, wherein the method comprises:

• converting rich metadata information into at least one of traversal information and search information of a property graph;
• providing at least one application programming interface according to at least one of a traversal process and a search process;
• setting relationships among entity nodes in the property graph by mapping;
• activating a GPU thread group;
• allotting video memory blocks;
• storing the property graph in a GPU as a mixed graph, wherein the mixed graph corresponding to the property graph includes graph architectures and service oriented architectures, in which the graph architectures are stored in a control and status register format and the service oriented architectures are stored as property arrays;
• activating a traversal program;
• performing detection and gathering on stored property arrays for iteration;
• and
• providing a result of the iteration to a search engine.

A graphic processing unit (GPU)-based device for optimizing rich metadata management, wherein the device comprises a central processing unit (CPU) processor and a GPU, wherein the CPU processor comprises a mapping module, a search engine and a management module, and the GPU comprises a traversal module and a storage module, wherein:

• the mapping module is configured to convert rich metadata information into a property graph, wherein edges of the property graph are relationships among at least one of users, jobs and data files as entity nodes of the property graph, and wherein properties of the property graph include properties of at least one of the entity nodes and properties of the relationships among the three entity nodes;
• the search engine is configured to convert the rich metadata into traversal search information of the property graph according to the search information of the rich metadata by calling an application programming interface;
• the management module is configure to:
• allot video memory of the storage module;
• and
• send the traversal search information to the traversal module;
• the traversal module is configured to:
• detect and gather the traversal search information of the property graph by iteration;
• and
• send frontier queue data formed through the iteration to the search engine;
• and
• the storage module is configured to store the rich metadata information as arrays.
