Abstract: A method of supporting persistence of a computing device is provided. The computing device performs a stop procedure upon power failure. In the stop procedure, the computing device schedules out a running process task, stores a state of the process task to a process control block of a memory module including a non-volatile memory, flushes a cache for the processor, and flushes a pending memory request.

Abstract: Provided is an apparatus for accelerating a graph neural network for efficient parallel processing of massive graph datasets, including a streaming multiprocess (SM) scheduler and a computation unit, wherein the SM scheduler obtains a subgraph and an embedding table per layer, determines a number of SMs to be allocated for processing embeddings of a destination-vertex based on a feature dimension and a maximum number of threads in each of the SMs, and allocates the determined number of SMs to each of all destination-vertices included in the subgraph, and the computation unit obtains, by each of the SMs, embeddings of a destination-vertex allocated to each SM, obtains, by each SM, embeddings of at least one or more neighbor-vertices of the destination-vertex using the subgraph, and performs, by each SM, a user-designated operation using the embeddings of the destination-vertex and the embeddings of the neighbor-vertices.

Abstract: A computational storage supporting graph machine learning acceleration includes a solid state drive (SSD) configured to store a graph data set; and a field-programmable gate array (FPGA) configured to download, to a memory, a graph machine learning model programmed in a form of a data flow graph by a host, wherein a hardware logic built in the FPGA performs access to the SSD through a peripheral component interconnect-express (PCIe) switch.
