摘要： An EGR system includes a high-pressure EGR unit and a low-pressure EGR unit. During the steady operation of an internal combustion engine, the high-pressure EGR gas and the low-pressure EGR gas are mixed with each other at a mixture ratio, in which the ratio of the high-pressure EGR gas amount to the entire EGR gas amount is higher than that in a known mixture ratio, and then recirculated back to the internal combustion engine. In the engine speed-up transitional operation period, the opening amount of a high-pressure EGR valve is adjusted to the opening amount that is much smaller than the target opening amount corresponding to the target operation mode. Thus, it is possible to suppress occurrence of the situation where the entire EGR gas amount is excessive in the period in which the low-pressure EGR gas amount does not decrease by a sufficient amount.
摘要翻译： EGR系统包括高压EGR单元和低压EGR单元。在内燃机的稳定运行中，高压EGR气体和低压EGR气体以混合比混合，其中高压EGR气体量与整个EGR气体的比率量高于已知混合比，然后再循环回内燃机。在发动机加速过渡运转期间，将高压EGR阀的开度调整为远小于与目标运转模式对应的目标开度的开度。因此，可以抑制在低压EGR气体量没有减少足够量的时段内EGR排气总量过多的情况的发生。

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.
