Abstract: A storage medium storing an image diagnosis support program for causing a computer to execute process that includes inputting input images to a first model that outputs, according to input images obtained by imaging a subject under the plurality of imaging conditions, an estimation result of a disease name of the, and a degree of contribution to estimation of each of input images for each of the imaging conditions; selecting, among input images, an image imaged under an imaging condition for estimation selected based on the degree of contribution; inputting the image imaged under the imaging condition for estimation to a second model that outputs an estimation result of a lesion part in the image according to the input image; and outputting the estimation result of the lesion part specified based on an output result of the second model.

Abstract: A non-transitory computer-readable recording medium having stored therein an evaluation program for causing a computer to execute a process including: specifying a plurality of partial images included in input image data by inputting the input image data into a detection model, the detection model being a machine learning model trained with a first training data set including a plurality of first training data each associating image data with a partial image which contains an extraction target from the image data; and evaluating the input image data by inputting the plurality of specified partial images into an evaluation model, the evaluation model being a machine learning model trained with a second training data set including a plurality of second training data each associating one or more partial images with an evaluation result of a target being a subject of an image containing the one or more partial images.

Abstract: A storage system includes a plurality of server nodes including a first server node and a second server node paired with the first server node, and a manager node configured to manage the plurality of server nodes, wherein the first server node is configured to transmit a notification to the manager node in response to detecting that the second server node is down, and the notification indicates that the second server node is down, and wherein the manager node is configured to execute a first process related to a second process executed by the second server node in response to receiving the notification.

Abstract: An information processing apparatus transmits a task executing request to a first control node to execute a task including multiple processes among multiple control nodes; and stores management information associating the task executing request transmitted to the first control node with a response result received from the first control node. The task executing request includes: a command to execute the task; a command to respond with a first notification indicating normal completion of the plurality of processes; a command to execute, when execution of at least one of the processes fails, a regaining process that regains statuses of one or more remaining processes successfully executed to statuses before being executed; and a command to response, when the regaining process is normally completed, a second notification indicating normal completion of the regaining process. Accordingly, the load on a control node managing multiple control nodes can be reduced.

Abstract: An information processing apparatus includes a memory; a processor coupled to the memory; and one or more resources, the processor being configured to allow a plurality of the processes to be performed on one of the one or more resources to obtain the exclusion in parallel by optimistic locking control in a first phase, and execute one of the plurality of processes on the resource in a state where the exclusion is obtained by pessimistic locking control in a second phase.

Abstract: A virtualization controller identifies a node that manages a segment to be accessed, and instructs the node to access the segment. A mirror controller of the node instructed to access the segment writes data in the segment managed by the node and in a segment having a mirror relation with the segment managed by the node.

Abstract: A control module that manages a segment to which data is written implements write processing and resynchronization processing using a bitmap managed for each LUN. In other words, the control module stores the bitmap for the managed LUN in a bitmap storage unit. A mirror LUN control unit sets a corresponding portion of the bitmap to 1, controls data write to a target segment and a mirror segment, and resets the bitmap to 0 when the data write to both of the segments is complete. A resynchronization control unit refers to the bitmap storage unit to perform the resynchronization processing.

Abstract: By providing a virtual integrated disk creating unit configured to create a single virtual integrated disk by virtually integrating storage areas of a plurality of storage devices, and a target setting unit configured to set a login target to which a login to the virtual integrated disk from an outside is made, the time to log in to storage areas in multiple storage device provided in another node can be reduced.

Abstract: A storage controller out of a plurality of storage controllers used in a storage system, each of the plurality of storage controllers being configured to control mirror processing of data, the storage controller comprising: circuitry configured to: determine a storage controller of a destination of an input and output request for a volume, out of the plurality of storage controllers, based on mirror device information where identifiers and priorities of the respective storage controllers are stored while being associated with each other for each of mirror processing units, and state information being for each of storage controllers and indicating whether the storage controller is normal or not, and issue the input and output request to the determined storage controller.

Abstract: A processor generates, according to difference information that represents a difference between stationary points in a volume that represents a management unit for a storage area and that is associated with a plurality of generations, aggregate information in which the difference information for the plurality of generations is aggregated. The processor is configured to associate the aggregate information with a state of the volume at an oldest stationary point. The processor is configured to associate update information for a volume that has been updated from a state of the volume at a latest stationary point.

Abstract: The first storage area stores original data of an update target that is to be updated by a host. The controller divides data to be written over the original data of the update target stored in the first storage area into a plurality of pieces of update data and thereby distributes the plurality of pieces of update data for each of successive addresses. The second storage area stores the plurality of update data distributed by the controller. The third storage area stores information in which an update area address, which is an address of the first storage area to be overwritten by the plurality of pieces of update data of the original data of the update target, is associated with a storage destination address, which is an address of the second storage area that has stored the plurality of pieces of update data.
