  • Patent number: 10522241
    Abstract: Methods and systems for accelerated input data conversion include partially parsing an input data set to convert the data set from a first format to a second format in an intermediate output having at least one unparsed portion to quickly perform a majority of the conversion. The partial parsing operates on portions of the input data set having a size less than a threshold size and leaves portions of the input data having a size greater than the threshold size unparsed. The intermediate output is parsed to convert at least one unparsed portion from the first format to the second format in a final output to complete the conversion such that a combined parsing time of the partial parse of the input data set and the parse of the intermediate output is accelerated relative to a single-stage parsing.

  • Patent number: 10518608
    Abstract: A vehicle air-conditioner safety device includes a controller which, in a case in which an abnormality has occurred in a heating device that heats coolant with a heater, determines whether or not the abnormality is a restorable abnormality or a non-restorable abnormality. When the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed. Heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred. Heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality.

  • Publication number: 20190341929
    Abstract: Methods and systems for storing data include compressing data inflated from a first compression format into a second format using a processor and verifying contents of the data concurrently with compressing the data. Compression is aborted responsive to a failure of the content verification, but an output of the compression is stored to a tape drive until the compression is aborted. The tape drive is rolled back to a file start position after the compression is aborted and compression of any remaining uncompressed data is skipped after the compression is aborted. The data is stored to the tape drive after rolling the tape drive back.

  • Patent number: 10419020
    Abstract: Methods and systems for storing data includes inflating received data having a first compression format. Blocks are created from the inflated data for a second compression format. The blocks are compressed in the second format using a processor. The contents of the blocks are verified concurrently with compressing the blocks. Compression is aborted if the verification of the contents fails. An output of the compression is stored if verification of the contents succeeds and storing the received data if verification of the contents fails.

  • Publication number: 20190213043
    Abstract: A method, system and computer program product for optimally allocating objects in a virtual machine environment implemented on a NUMA computer system. The method includes: obtaining a node identifier; storing the node identifier in a thread; obtaining an object identifier of a lock-target object from a lock thread; writing a lock node identifier into the lock-target object; traversing an object reference graph where the object reference graph contains an object as a graph node, a reference from the first object to a second object as an edge, and a stack allocated to a thread as the root node; determining whether a move-target object contains the lock node identifier; moving the move-target object to a subarea allocated to a lock node if it contains the lock node identifier, and moving the move-target object to the destination of the current traversal target object if the lock node identifier is not found.

  • Publication number: 20190188113
    Abstract: Described is a computer-implemented method of reordering condition checks. Two or more condition checks in computer code that may be reordered within the code are identified. It is determined that the execution frequency of a later one of the condition checks is satisfied at a greater frequency than a preceding one of the condition checks. It is determined that there is an absence of side effects in the two or more condition checks. The values of the condition checks are propagated and abstract interpretation is performed on the values that are propagated. It is determined that the condition checks are exclusive of each other, and the condition checks are reordered within the computer code.
