Provided is an apparatus for accelerating graph neural network (GNN) pre-processing, the apparatus including a set-partitioning accelerator configured to sort each edge of an original graph stored in a coordinate list (COO) format by a node number, perform radix sorting based on a vertex identification (VID) to generate a COO array of a preset length, and perform uniform random sampling on some nodes of a given node array, a merger configured to merge the COO array of the preset length to generate one sorted COO array, a re-indexer configured to assign new consecutive VIDs respectively to the nodes selected through the uniform random sampling, and a compressed sparse row (CSR) converter configured to the edges sorted by the node number into a CSR format.

Method and apparatus for accelerating GNN pre-processing

A data storage device includes one or more nonvolatile memory devices each including a plurality of unit storage spaces; and an address recommending circuit configured to recommend a unit storage space among the plurality of unit storage spaces to process a write request, wherein the address recommending circuit applies feature data to a neural network to recommend the unit storage space, and wherein the feature data is generated based on request information for the write request, a target address corresponding to the write request, an address of data stored in the plurality of unit storage spaces.
