THE COMPUTER CLUSTERS WITH FAST SYNCHRONIZATION OF MESSAGES AND WITH FAST DISTRIBUTED COMPUTING BY THE NETWORK HARDWARE
The network structure and methods for the rapid interaction of computers in a distributed composite cluster are proposed. The composite cluster is organized hierarchically and consists of a group of simple clusters, one of which gives tasks to simple clusters. Simple clusters perform tasks synchronously and asynchronously. In the simple cluster, a group of processors also acts synchronously or asynchronously, using fast barrier synchronization. The activities of simple cluster computers are controlled by a leading computer. The composite cluster quickly performs the processes of synchronization of messages sent, processes to resolve conflicts of computer access to network tools, distributed logical operations, the distributed definition of max and min , distributed addition and subtraction operations. These operations do not require message delay to complete. The duration of operations does not depend on the number of cluster computers participating in them. To do this, computers send messages simultaneously, creating a group message in which the bits of the same name are combined in time. Acceleration of the above mentioned distributed computing and synchronization are achieved with intensive computer access to the cluster network, which distinguishes the proposed solutions from the existing practice of using a computer network. The proposed operations allow creating faster algorithms for real-time tasks, including tasks for managing the cluster.
