A fluid-heating device for heating fluid with a heater includes: a heating portion that is molded so as to cover the surrounding of the heater; and a support body integrally cast into the heating portion, the heating portion being molded in a state in which the heater is supported by the support body in a die for molding the heating portion.

Fluid-heating device and manufacturing method thereof

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.

Methods and systems for managing data redundancy include registering certified commands, input files, output files, and arguments in an execution history list after execution of said certified commands. An existing output file is provided in response to execution of a first certified command that matches an entry in the execution history list. A file is deleted if the file is reproducible from another file using a second certified command. The deleted file is registered in a reproducible file list. The deleted file is reproduced upon request using the second certified command.

File system for genomic data

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.

Object optimal allocation device, method and program

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.

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.

A fluid-heating device for heating fluid includes: a heater having a heat generating part, the heat generating part being configured to generate heat upon application of current; an electric component configured to control the application of the current to the heater; a tank having an opening portion, the tank being configured to accommodate the heat generating part; a top-plate portion configured to close the opening portion of the tank, the top-plate portion being configured to form a fluid chamber through which the fluid flows; and a first communication port and a second communication port configured to allow the fluid to flow through the fluid chamber; wherein the electric component is provided on an outer side of the fluid chamber along the top-plate portion.

A fluid-heating device for heating fluid includes a heater unit configured to have a heater and a heating portion, the heating portion being formed as to cover surrounding of the heater, wherein the heating portion has an inner heat exchange surface formed on an inner surface of a through hole penetrating through an inner side of the heater and an outer heat exchange surface formed on an outer-wall portion of an outer side of the heater, the inner heat exchange surface being configured to perform heat exchange with the fluid, and the outer heat exchange surface being configured to perform the heat exchange with the fluid.

A system and method suppresses occurrence of stalling caused by data dependency other than register dependency in an out-of-order processor. A stall reducing method includes a handler for detecting a stall occurring during execution of execution code using a performance monitoring unit, and for identifying, based on dependencies, a second instruction on which a first instruction is data dependent, the stall based on this dependency. A profiler registers the second instruction as profile information. An optimization module inserts a thread yield instruction in an appropriate position inside execution code or an original code file based on the profile information, and outputs optimized execution code.

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.

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.

A method, an apparatus, and a computer program product for optimizing variable size arguments in a programming language are provided. The method includes finding, in a target program, a call site having a variable-length argument. The method also includes generating a converted code for a callee of the call site, the generating including converting the variable-length argument to a plurality of arguments. The method further includes translating the call site to a call code for calling the converted code with the plurality of arguments instead of the variable-length argument.
