摘要： Systems, methods and computer program products for operation history management for high performance computing programs optimization. Exemplary embodiments include a method including in response to saving an operation history creating a pseudo-change file that includes marks above and below an operation area in order to specify an operation object, creating a change history by storing context differences between contents of a file before an operation and the pseudo-change file, including the context differences in an operation history list, in response to applying the operation history applying the context differences to an objective operation file to acquire the pseudo-change file, determining the application area based on a position of the marks above and below the operation area from the pseudo-change file; and acquiring edited results by applying the context differences from the operation history to the objective application file.

摘要： To improve communication efficiency during the updating of a replica, and to reduce the amount of memory required for the updating of a replica. The present invention is a computer for maintaining consistency of replica contents by interchanging data modification with another computer. The computer includes: a replica including shared data; a receiver for receiving, from another computer, a modification request for data included in the replica; and a controller for controlling, regardless of a receiving order of the modification request, for each receipt of the modification request, a timing of update execution for the replica in accordance with the received modification request by using information included in the modification request. The timing of replica updating in accordance with the received modification requests can be determined, regardless of the order in which the modification requests are received, that is, the order of the transmission from other computers. Therefore, communication efficiency can be improved and the amount of required memory can be reduced.

摘要： An apparatus and method for enabling disassembly of packets into their components and for assignment of main storage areas without software intervention in the reception processing of a communications network. Direct partition is enabled by hardware without intervention of software by adding control information directly accessible by the receiving DMA feature 6 to each communications packet. The transmitting DMA feature 6 transfers the contents of the DMA command queue to the communications control unit 7 before transferring the data in computer storage 10 to the communications control unit 7. This information is added to the top of each packet before being passed to the receiving end. The receiving DMA feature 6 transfers each whole packet not to a single reception buffer but to different reception buffers in element data units by use of both this information and the information in the DMA command queue at the receiving end. Communications software makes use of each reception buffer as it is without copying it onto another area.
