A parallel computer operates to reduce data held by a plurality of nodes. Each node constituting a parallel computer transfers the data divided into n to other nodes, and each node summarizes the respective 1/n data and operates, then a plurality of nodes transfer the respective operation result to a summarizing node. Since all the nodes execute operation for divided data respectively, reduction processing time can be decreased. And more nodes (network adapters) can participate in data transfer through the first and second data transfers, high-speed transfer processing can therefore be implemented, and transfer time can be decreased.
摘要:
A network system broadcast data from one node to a plurality of other nodes, which can decrease the time required for broadcast. A transfer source node divides the transfer data to be broadcasted, and transfers each divided data separately from the network adapters of the transfer source node to the network adapters of the other nodes, and the other nodes transfer the received data to the network adapters of the other nodes other than the transfer source node. Since more nodes (network adapters) can participate in data transfer in the second data transfer, high-speed transfer processing can be implemented, and the transfer processing time for broadcast can be decreased.

Fe alloy containing Si more than 4.0 wt % is produced by a thin plate casting process. The producing condition depends upon rapid solidification of Fe alloy from a molten condition at cooling rate of more than 1.degree. C./sen to less than 10.sup.5 .degree. C./sec.The obtained thin cast plates are subjected to a hot rolling of more than 30% at the temperature range of 600.degree. to 800.degree. C., and to the cold rolling to a determined thickness, followed pickling. By the above mentioned conditions, operations of the industrial scale may be practiced without cracks on the surface in the cold rolling excellent magnetic characteristics may be provided by passing the annealing after the cold rolling.

A protective relaying system in which the electric stations at both ends of a district of a power system to be protected optically transmit and receive reciprocally the information of the electric stations. A first protective relay device responds to both the electrical quantities from the opposite side terminal and electrical quantities of its own side terminal, and a second protective relay device responds only to the electrical quantities of its own side terminal. The respective protective relay devices are controlled by virtue of error detection circuits and signal discontinuity detection circuits connected to the optical transmission line to thereby discriminating the mere failure in the optical transmission line from the concurrent failures in both the optical transmission line and the transmission line so as to rapidly eliminate the failures.
