    摘要： A method and system to acquire checkpoints in making iteration-method computer calculations in parallel and to effectively utilize the acquired data for recovery. At the time of acquiring a checkpoint in parallel calculation that repeats an iteration method, each node independently acquires the checkpoint in parallel with the calculation without stopping the calculation. Thereby, it is possible to perform both of the calculation and the checkpoint acquisition in parallel. In the case where the calculation does not impose an I/O bottleneck, checkpoint acquisition time is overlapped, and execution time is reduced. In this method, checkpoint data including values at different points of time during the acquisition process is acquired. By limiting the use purpose to iteration-method convergence calculations, mixture of the values at the different points of time in the checkpoint data is accepted in the problem that a convergence destination does not depend on an initial value.

    摘要： An internal combustion engine that selectively switches from a first combustion in which an amount of an exhaust gas recirculation gas within a combustion chamber is more than the amount of the exhaust gas recirculation gas when an amount of soot generated reaches a peak amount to generate substantially no soot, that is, a low temperature combustion, and a second combustion in which the amount of the exhaust gas recirculation gas within the combustion chamber is less than the amount of the exhaust gas recirculation gas when the amount of soot generated reaches the peak amount. The switching is selectively performed, such that, a stable low temperature combustion corresponding to the air fuel ratio is performed by shifting the area for performing the low temperature combustion to the high load side as the air fuel ratio is reduced.
