The invention discloses a method and a system for distributing data in a high-performance computer cluster. The high-performance computer cluster comprises a central control node and M computing nodes, wherein M is an integer more than or equal to 2, and the appointed data is distributed to the M computing nodes by the central control node. The method comprises the following steps: dividing the M computing nodes into m layers, wherein m is the integer more than or equal to 2; dividing the appointed data into k parts, wherein k is the integer more than or equal to 2; distributing the k parts of data to a first layer of computing nodes as sub-nodes of the central control node by the central control node; obtaining at least one part of the data by each computing node in the first layer; distributing the at least one part of data, which is distributed by a father node of the computing nodes, to the sub-computing nodes of the computing nodes; and asking the other computing nodes for the rest of the appointed data by the computing nodes, thereby obtaining all the appointed data. By utilizing the method and the system, the data can be quickly distributed to all the computing nodes in the high-performance computer cluster.

The invention discloses an NFC control-based intelligent household appliance, which comprises a household appliance and a mobile terminal, wherein the household appliance is provided with an NFC module and / or an electric control board; the electric control board is provided with an MCU module and a WIFI module; the MCU module exchanges data with the NFC module and the WIFI module respectively; the mobile terminal is loaded with an APP for being connected with a cloud-end database, downloading networking resources and communicating with the NFC module for exchanging distribution network data; and the NFC module is a medium for wireless communication between the mobile terminal and the MCU module. Quick distribution network is realized through the mobile terminal, the NFC module and the electric control board; the NFC module mainly plays roles of simplifying the distribution network process and shortening the distribution network time during the whole system; the structure is simple and reasonable; the operation is simple and quick; and the distribution network success rate is high.

A P2P network dynamic load balancing method based on prediction and area division belongs to the field of network file transmission; including obtaining node resource utilization; judging whether the node resource utilization exceeds the high load area threshold, if yes, execute step e, if not, execute step c; Predict the next access volume according to the current file access situation of the node; determine whether the file becomes a hot file, if so, execute step e, if not, execute step a; broadcast to the surrounding nodes to obtain the load information of the surrounding nodes; determine whether it is in a high Load area, if so, execute the high-load area load balancing module, if not, execute the low-load area load balancing module; the server creates a copy of the hotspot file, and proceeds to step a; the present invention can well realize the load balancing of the actual system network.

The invention discloses an upgrade method, device, equipment and storage medium without interrupting service. According to the existing upgrade method, the software upgrade action of the upgrade service is coupled with the software upgrade action of the hyper-converged system, and the upgrade service cannot be as expected. For the problem of providing new upgrade services, by decoupling the upgrade and maintenance work of the upgrade service from the upgrade and maintenance work of the hyper-converged software, after the upgrade and reloading of the upgrade service software, it can be completed without interrupting the upgrade service in the early stage. For the upgrade of the upgrade service software, configure the local Yum repository on the upgrade control node and provide the Yum repo based on the HTTP protocol as an online software source in the hyper-converged system cluster; then configure the Yum of each node in the hyper-converged system cluster. The repo points to the repo address where the online software source is located, which avoids distributing the ISO to each node, and can relatively reduce the software distribution time during the upgrade process.

The invention provides a data dissemination method in a wireless sensor network, and is particularly suitable for scenes for performing program wireless updating on a sensor network node. The method comprises the following steps of: dividing high-capacity dissemination data into data blocks of fixed sizes, and dividing the data blocks into a preset number of data packets with fixed lengths, wherein each data packet corresponds to a unique sequence number; and receiving the data packets received by a node according to a bit vector mark, and requesting to retransmit the lost packets, wherein nodes at different distances away from a data source in a network can synchronously transmit the data blocks with different numbers to form pipeline transmission and regularly send and receive the data by a time division multiple access (TDMA) method according to a time slot; when a conflict is detected, a time slot table is dynamically adjusted and exchanged, so that subsequent conflicts can be reduced, and redundant data receiving is also reduced; and a plurality of sending nodes can send the data packets according to different starting sequence numbers, so that the data dissemination time can be shortened, and energy consumption in a data dissemination process can be reduced.
