Abstract: Test data may be generated by classifying a plurality of medical records of patients into a plurality of groups, based on at least an execution characteristic of a processing program that processes the medical records, and generating test data including at least a part of the plurality of medical records based on proportions of the number of the medical records classified into the plurality of groups.

Abstract: A blockchain processing method and system for verification of deleted data for blockchains. An item of data is deleted from a block of a blockchain by: identifying the block of the blockchain storing the item of data; deleting the item of data from the identified block without deleting a hash value associated with the deleted item of data from the identified block; and adding metadata to a new block of the blockchain identifying the deleted item of data. The metadata includes a block identifier (ID) of the identified block as a location of the deleted item of data as well as the hash value associated with the deleted item of data. The block ID may comprise a root hash in a block header of the identified block, a universally unique identifier (UUID) allocated to the identified block, or an offset from the new block to the identified block.

Abstract: A technique of operating a system is provided that processes data with one or more data processing modules provided in parallel. A synchronization token is input into at least one data processing module that is in an operational state from the one or more data processing modules provided in parallel, in response to a request to change allocation of the data. The allocation of the data is changed to the one or more data processing modules provided in parallel, after the synchronization token is input. In response to the synchronization token having arrived at a data processing module at a later stage, the at least one data processing module, that stopped the processing, starts processing data after the synchronization token is input to the at least one data processing module.

Abstract: Traffic data while the system is in operation is collected for a certain time as a preprocess. Typical patterns are extracted from the collected traffic data. Next, stream programs are created for the individual typical patterns and stored for the future reference. Next, the IDs of alternative tasks for transition among different stream programs are stored. In actual system operation, the system measures traffic data regularly or at any time, compares the resultant patterns with the typical patterns, and selects a stream program corresponding to the closest typical pattern as the next phase. Program shutdown time when shifting from the stream program in the present phase to the next phase can be reduced by gradually shifting empty tasks in the present phase to the next stream program as alternative tasks in consideration of the cost of switching between tasks, the cost of transferring data among resources, and so on.

Abstract: A method, system, and article of manufacture for solving ordinary differential equations described in a graphical model with nodes as blocks and dependencies as links using the processing of a computer with a plurality of processors. The method includes: generating segments of block with or without duplication for each block with an internal state and for each block without any output by traversing the graphical model from each block with an internal state to each block without any output; merging the segment to reduce duplication; compiling and converting each segment from the merged results in an executable code; and individually allocating the executable code for each segment to a plurality of processors for parallel execution.

Abstract: A system processing an application in a hybrid system includes a database comprising a plurality of libraries, each library comprising sub-program components, wherein two or more of the components are combined by an end user into a stream flow defining an application. The system also includes a plurality of resources configured to process the stream flow, architecture of at least one of the plurality of resources being different from architecture of another of the plurality of resources. The system also includes a compiler configured to generate a resource assignment assigning the plurality of resources to the two or more of the components in the stream flow, at least two of the two or more of the components in the stream flow sharing at least one of the plurality of resources according to the resource assignment.

Abstract: A method, system and computer program product for optimizing performance of an application running on a hybrid system. The method includes the steps of: selecting a first user defined operator from a library component within the application; determining at least one available hardware resource; generating at least one execution pattern for the first user defined operator based on the available hardware resource; compiling the execution pattern; measuring the execution speed of the execution pattern on the available hardware resource; and storing the execution speed and the execution pattern in an optimization table; where at least one of the steps is carried out using a computer device so that performance of said application is optimized on the hybrid system.

Abstract: A printer according to the invention includes a keyboard provided with a cursor key and a mode selection key for selecting a double-width mode, a display for displaying inputted data, a cursor displayed on the display and shifted by operating said cursor key for indicating a position of the data to be processed, a double-width mark displayed on a digit adjacent to a double-width character on the display in the double-width mode, and a controlling means for controlling the double-width mark to be displayed in conjunction with the double-width character and for controlling the cursor when shifted by operating the cursor key to indicate only a double-width character while avoiding a double-width mark.
