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.
摘要翻译：一种在并行计算迭代法计算机中获取检查点的方法和系统，并有效利用获取的数据进行恢复。在重复迭代方法的并行计算中获取检查点时，每个节点在不停止计算的情况下独立地获取与计算并行的检查点。由此，可以并行地执行计算和检查点采集两者。在计算没有施加I / O瓶颈的情况下，检查点获取时间重叠，执行时间减少。在该方法中，获取包括在采集处理期间的不同时间点的值的检查点数据。通过将使用目的限制在迭代法收敛计算中，在收敛目的地不依赖于初始值的问题中接受检查点数据中不同时间点的值的混合。

摘要： A system including multiple nodes performing radio communication, wherein each node stores routing information, uses it to determine a transmission path, and performs cut-through transmission by transmitting and receiving packets to and from a node on the determined path through transmission and reception radio waves given a directivity by controlling their phases. In the system, time synchronization and transmission and reception of packet communication records are performed during a certain time period by carrying out the cut-through transmission while controlling phases of the radio waves so that all of the nodes form one or more closed loops. The node transmits and receives packets in accordance with routing information and a time frame assigned to each of the nodes as a time when each node is allowed to transmit and receive a packet, updates the routing information, and shares it with each node.

摘要： A system including multiple nodes performing radio communication, wherein each node stores routing information, uses it to determine a transmission path, and performs cut-through transmission by transmitting and receiving packets to and from a node on the determined path through transmission and reception radio waves given a directivity by controlling their phases. In the system, time synchronization and transmission and reception of packet communication records are performed during a certain time period by carrying out the cut-through transmission while controlling phases of the radio waves so that all of the nodes form one or more closed loops. The node transmits and receives packets in accordance with routing information and a time frame assigned to each of the nodes as a time when each node is allowed to transmit and receive a packet, updates the routing information, and shares it with each node.
